This document summarizes a study conducted in Nairobi, Kenya between January and March 2005 regarding waste incineration practices that release persistent organic pollutants into the environment. The study focused on medical and municipal waste burning, which is a major method of waste disposal in Nairobi. The study found that burning waste openly and through industrial incinerators is common due to a lack of proper waste management systems and legal guidelines. However, waste burning releases dioxins and furans and poses health and environmental risks. The study recommends alternative non-incineration waste treatment technologies and improved regulations to promote more responsible waste management in Kenya.

This document summarizes a study conducted in Nairobi, Kenya that investigated waste incineration practices which release dioxins and furans into the environment. The study found that burning is the dominant method of waste disposal in Nairobi, including through industrial incinerators and open burning. Burning waste is preferred due to a lack of proper waste management by the city and unclear legal guidelines. However, burning waste is a source of unintended persistent organic pollutants like dioxins that can harm human health and the environment. The report recommends alternative non-burning waste treatment technologies and improved regulations to address this challenge.

This report estimates the scale of global food waste for the first time using comprehensive new data collection and modelling. It finds that approximately 931 million tonnes of food is wasted yearly, with household food waste making up around 570 million tonnes of this total. The report also finds that per capita food waste generation is broadly similar across high, middle and low income countries. This challenges previous narratives that concentrated consumer food waste in developed nations. Additionally, the report develops a new methodology for countries to measure food waste at the household, food service and retail levels in order to track progress towards UN Sustainable Development Goal 12.3 of halving food waste by 2030. This will allow for consistent global reporting and evidence-based food waste reduction

This document provides an assessment report on Kenya's transition to a green economy. It finds that Kenya has already taken steps toward greening its economy through policies supporting renewable energy, sustainable natural resource use, and green economy mainstreaming. Quantitative modeling of green investment scenarios in key sectors like agriculture, energy, manufacturing and transport show that in the short-term, GDP growth would not be substantially different than under a business-as-usual scenario. However, in the long-term, a green economy could yield 12% higher GDP by 2030 alongside a cleaner environment and higher productivity. Green investments could also lower energy use and carbon emissions compared to business-as-usual. The report concludes that Kenya's transition to a green economy has the

Municipal solid waste generation is predicted to grow from 2.3 billion tonnes in 2023 to 3.8 billion tonnes by 2050. In 2020, the global direct cost of waste management was an estimated USD 252 billion. When factoring in the hidden costs of pollution, poor health and climate change from poor waste disposal practices, the cost rises to USD 361 billion. Without urgent action on waste management, by 2050 this global annual cost could almost double to a staggering USD 640.3 billion.
The report’s modelling shows that getting waste under control by taking waste prevention and management measures could limit net annual costs by 2050 to USD 270.2 billion. However, projections show that a circular economy model, where waste generation and economic growth are decoupled by adopting waste avoidance, sustainable business practices, and full waste management, could in fact lead to a full net gain of USD 108.5 billion per year. We need to act now in order to avoid the worst scenario. The report provides guidance and suggested actions for Multinational development banks, national governments, municipalities, producers and retailers, the waste management sector as well as citizens.

It discusses the origins and goals of the Health Care Without Harm campaign, which aims to eliminate medical waste incineration due to health and environmental concerns. It notes the lack of comprehensive information previously available on non-incineration options. The preface describes how the campaign was formed and what it has learned over time, including that most healthcare waste is similar to household waste and can be reduced, reused or recycled rather than treated. It establishes the goals of the resource as encouraging waste minimization approaches and providing information to evaluate non-incineration technology options while raising questions about their impacts.
This document compares two processes for energy utilization of wet waste biomass streams: supercritical water oxidation (SCWO) and sub-critical hydrothermal conversion (HTC). SCWO generates heat and phosphorus while HTC generates diesel oil and nitrogen. The environmental performance of the two processes was analyzed using life cycle assessment for treating turkey slaughtering waste and sewage sludge. The analysis found that both processes can be environmentally attractive options if they replace fossil fuel use and capture landfill gas, with SCWO performing better when heat is recovered and HTC performing better if landfill gas is not recovered.

This document summarizes the status and perspectives of waste incineration in China. It discusses that currently over 60 waste incineration plants are operating in China, with plans to build around 400 new plants over the next decade. However, waste incineration currently plays a minor role in waste disposal in China due to the high costs and low calorific value of municipal solid waste from its high organic content and water. The document also reviews the composition and management of municipal solid waste in China.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Kunio yoshikawa innovative japanese waste to-green product technologies econo...Tung Huynh
The document discusses three innovative Japanese technologies for converting waste into valuable products:
1) Waste-to-coal technology uses hydrothermal treatment to convert municipal solid waste and medical waste into coal substitute fuel.
2) Waste-to-fertilizer technology treats sewage sludge and food waste through hydrothermal and mechanical processes to produce liquid fertilizer and solid fuel.
3) Waste-to-electricity technology gasifies chicken manure in a fixed bed updraft gasifier to generate syngas used for electricity production, while also producing biochar fertilizer.
The document provides design details for a solar maximum power point tracking (MPPT) controller for use in an off-grid solar street lighting system. Key points:
1. The controller uses a flyback converter topology and MPPT algorithm to extract power from the solar panel at its maximum power point and regulate the output voltage to charge lead-acid batteries.
2. An evaluation shows the MPPT algorithm can track the solar panel's maximum power point with less than 5% error under changing lighting conditions, improving efficiency over a simple linear regulator.
3. A circuit description, layout, bill of materials, and performance test results are provided for a 30W prototype solar controller designed around an NCP1294 controller
This study piloted pyrolysis and gasification of abattoir solid wastes and reviewed using the wastes in boilers. Pyrolysis and gasification of dried paunch waste and DAF sludge were technically successful, producing char and syngas. However, waste processing fees of $65-90/tonne would be required for commercial viability. Co-combusting dewatered wastes in boilers could reduce costs. Thermal processing of wastes offers significant greenhouse gas reductions compared to current disposal methods.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

About the International POPs Elimination Project
On May 1, 2004, the International POPs Elimination Network (IPEN http://www.ipen.org ) began a
global NGO project called the International POPs Elimination Project (IPEP) in partnership with the
United Nations Industrial Development Organization (UNIDO) and the United Nations Environment
Program (UNEP). The Global Environment Facility (GEF) provided core funding for the project.
IPEP has three principal objectives:
• Encourage and enable NGOs in 40 developing and transitional countries to
engage in activities that provide concrete and immediate contributions to country
efforts in preparing for the implementation of the Stockholm Convention;
• Enhance the skills and knowledge of NGOs to help build their capacity as effective
stakeholders in the Convention implementation process;
• Help establish regional and national NGO coordination and capacity in all regions
of the world in support of longer-term efforts to achieve chemical safety.
IPEP will support preparation of reports on country situation, hotspots, policy briefs, and regional
activities. Three principal types of activities will be supported by IPEP: participation in the National
Implementation Plan, training and awareness workshops, and public information and awareness
campaigns.

EXECUTIVE SUMMARY
This report outlines the findings of a study carried out in and around the city of
Nairobi, Kenya by ENVILEAD. The study was carried out between the months of
January and March 2005, about the patterns of practice that are likely to release
persistent organic pollutants (POPs) into the environment as part of the
International POPs Elimination Project (IPEP’s) initiatives.
The focus of the study was the practice of medical and municipal waste burning,
which research has shown to be a potential source of unintentional POPs (U-
POPs). The study’s objective was to investigate the anatomy of this practice,
identify the key issues involved and make recommendations for the way forward.
It was established that burning is the dominant method of waste disposal in the
city, and this is done through industrial incinerators and in the open air. The main
reason for this preferred method of disposal is its convenience in the absence of
a functioning system of waste management (by the City Council) and in the
absence of adequate legal guidelines on the disposal of solid waste by the
government. This practice is however also associated with several other factors
such as lack of awareness on the part of the public, economic pressures and the
general paucity of administrative capacity in Less Organized Countries (LOCs).
The study was able to establish that the area around the Dandora dumpsite, the
city’s biggest waste burning site, is highly contaminated with POPs. This was
established from the results of U-POPs levels in eggs sampled from the site in a
different study. There is also a high likelihood of other sites, such as the Kenyatta
National Hospital (KNH) incinerator, whose maximum temperatures range
between 600°C and 700°C and has no Air Pollution control Devices (APCD), and
open-air burning site and Kitengela open burning site being U-POPs hotspots.
The study came up with the following key recommendations for the way forward:
Additional research needs to be undertaken in order to gather more detailed
information regarding this pattern of practice. Among the additional research
required is in the area of relationship between the socio-economic dynamics
and the practice, quantification of the levels of dioxin (as well as other organic
pollutants and heavy metals) emissions from the identified sites, and
establishment of the impacts of the same on public health;
The legal framework for the safe disposal of solid waste, based on Best
Available Techniques (BAT) and Best Environmental Practices (BEP), should
to be addressed;
The plastics industry, as a major contributor of difficult-to-manage waste,
needs to be fully engaged in the search for solutions in the city’s waste
management programme;
Greater effort should be placed in the development of alternative technologies
for safe waste disposal, which should be affordable and sustainable;
8. 2
A popular appreciation of the science of ecology needs to be created in the
country, as a means of ensuring sustained grassroots support for
environmental conservation efforts.
INTRODUCTION
Background
Just as the generation of waste involves a complex interplay of social, cultural,
economic and technological processes, the proper management of waste cannot
be divorced from the same processes. While it is necessary, for conceptual
purposes, to view waste management as a clear and distinct category of activity
in society, in practice any successful waste management strategy has to address
such diverse issues as patterns of consumption, incentive systems (the
economics of waste management), waste handling technology, and legal
frameworks. In its broadest sense, the issue of waste management is an aspect
of the search for sustainable development strategies.
This report seeks to provide an overview of the critical issues regarding the
management of municipal and medical waste in Nairobi, especially in respect of
the potential danger of generating unintentional POPs (U-POPs) in the process
of burning such waste. The study’s broader objective is to assist in the
development of a comprehensive waste management strategy for the city and
other urban areas in the country, in the context of the provisions of the Stockholm
Convention on Persistent Organic Pollutants (POPs). Annex C of the Stockholm
Convention, identifies waste incinerators, including co-incinerators of municipal,
hazardous or medical waste or of sewage sludge, as source categories with high
potential to release U-POPs into the environment.
Municipal and medical waste was selected for study because of its large quantity
as a percentage of the total waste generated1
, and the complex nature of issues
involved in the proper management of these two types of waste. Nairobi City
Council (2002) admits that it is unable to manage waste effectively in the city,
and of particular concern was the proliferation of informal medical facilities, some
of which are located within residential areas.
The Environmental Management and Coordination Act (1999), is well placed to
manage waste, including POPs-contaminated waste, it gives provisions for
setting of standards, licensing of waste disposal sites and control of hazardous
waste. However, lack of enforcement mechanism is the biggest challenge facing
waste management in Kenya (Nairobi City Council, 2002).
1
A report by NEMA reveals that Nairobi generates approximately 2000 tonnes of waste per day. Of this,
68% is municipal waste generated from households (East Standard 2004)
9. 3
Kenya as a country is in the process of developing a National Health Care Waste
Management Plan. The National AIDS Control Council has just received funds
from the World Bank toward the cost of Kenya’s HIV/AIDS Disaster Response
Project, part of the funds are to be used in the development of a National Health
Care Waste Management Plan (Daily Nation, 2005).
The lack of enforcement of the relevant environmental law, among other key
factors, has led to a chaotic situation in which almost anything goes as far as the
handling of waste is concerned. A recent report by KIPPRA on solid waste
management in Kenya shows that only 25% of the solid waste generated daily in
the city of Nairobi is currently collected (UNEP 2005).
The focus of the study was waste burning, which any casual observation reveals
to be the preferred waste disposal option for the Nairobi residents, which is a
consequence of failure on the part of the City Council, and Government, to
institute organized systems waste handling. The study looked at open air burning
types and industrial incinerators.
Burning and POPs Generation
Polychlorinated dibenzo-p-dioxins (PCDD) and Polychlorinated dibenzofurans
(PCDF), Hexachlorobenzene (HCB) and Polychlorinated Biphenyls (PCBs) are
unintentional persistent organic pollutants (U-POPs), formed and released from
thermal processes involving organic matter and chlorine as a result of incomplete
combustion or chemical reactions. These U-POPs are commonly known as
dioxins because of their similar structure and health effects (Tangri 2003).
These U-POPs are both of natural and anthropogenic origin. They resist
photolytic, biological and chemical degradation. They are bio-accumulative,
widespread geographically and are toxic to life. The concentration of U-POPs of
anthropogenic origin has greatly increased over the years. Toxics Link Report
(2000) identifies several potential sources of these U-POPs, among them being
medical waste incineration and open burning of domestic waste.
According to USEPA estimates, municipal solid waste incineration and medical
waste incineration are among the top sources of dioxins released into the air.
They make up for 1,100gm TEQ/year and 477gm TEQ/year respectively (USEPA
1998). Of all source categories, combustion sources account for nearly 80% of
air emissions.

Luscombe and Costner (2003) show how incinerators endanger public health
and the environment in general. They identify the toxic pollutants in incinerator
gases and residues, and enumerate the human health and environmental
damage of the various chemicals in the incinerator releases. Connett (1998)
shows how municipal waste incineration is a poor solution to the waste
management problem. He lists the toxic emissions of incineration and shows how
dioxins, furans and other by-products of combustion impact human health and
the environment.
Objectives of Study
The overall goal of the study was to understand the (social, economic and
technological) dynamics of the practice of waste burning in the city and to find out
how this might contribute to the release of U-POPs into the environment. Other
critical issues, such as the public health impact of the pattern of practice, were
left for the next phase of the study.
The specific objectives of the study were:
i. to assess the extent of waste burning/incineration within Nairobi
ii. to establish the City Council of Nairobi’s role in the prevalence of open
burning and incineration as the preferred methods of waste disposal
iii. to identify the location of waste burning/ incineration sites in the city
iv. to find out how chlorine-containing waste (such as PVC plastics) is
disposed
v. to assess the level of awareness of the general public about the adverse
consequences of waste incineration

vi. to examine Government regulatory mechanisms for disposal of chlorine-
containing waste
vii. to explore suitable BAT and BEP for waste management in Kenya.
Significance of Study
Article 5 of the Stockholm Convention requires parties, Kenya included2
, taking
measures to reduce or eliminate releases from unintentional production of POPs.
These measures include:
i. reduction of annual total releases derived from anthropogenic sources of
U-POPs, with the goal of their continuing minimization and where feasible,
ultimate elimination;
ii. the development of an action plan (NIP) by parties. Kenya’s NIP should be
ready by 25th
December, 2006; and
iii. to promote BEP and incorporate BAT in the NIP.
The study’s findings will be incorporated in Kenya’s NIP of the Stockholm
Convention with a view to assisting in the realization of the above measures.
METHODOLOGY
To achieve the objectives of this study, both primary and secondary data was
used. Primary data comprised local views, perceptions and opinions related to
the waste disposal sites among local community members. Various Government
and other resource persons also provided valuable primary data for the study.
The state of the incinerators and dumpsites as well as the disposal methods
were studied through observation by the researchers. Additional data was
gathered through taking photographs of the sites and interviewing workers
(where applicable) at the different sites visited.
Secondary data was obtained from both published and unpublished information
on waste burning in Kenya and elsewhere in the world. Previous studies carried
out on medical and municipal waste disposal at the global, regional, national and
local levels were reviewed. Descriptive analysis was used to summarize the
collected data.
Scope of the Study
The study was a preliminary investigation, intended to open the way for further
detailed investigations of the same sites and other similar sites in the country.

Preparation for the Study
Staff recruitment and training: Two research assistants were recruited and
trained for fieldwork.
Stakeholders’ identification: Various stakeholders were identified and
approached for their views on the issue under investigation. These stakeholders
included:
i. Members of public within Nairobi
ii. Health care professionals
iii. The Occupational Health Officer, Ministry of Health
iv. National Environmental Management Authority (NEMA)
v. Kenya Association of Manufacturers
vi. Major Supermarkets in town
vii. Private waste handlers
viii. City Council of Nairobi
Locations of Interest
For the study of medical waste management, researchers chose to visit a few
health care institutions based in Nairobi. These were: Kenyatta National Hospital
(KNH), Nairobi Hospital, Mater Hospital and Forces Memorial Hospital. For the
study of municipal waste management, the researchers visited the Nairobi City
Council’s dump site at Dandora as well as several residential estates in Nairobi
including: Jericho, Kariobangi, Huruma, Ngomongo, Baba dogo, Muthurwa,
Shauri moyo, Kimathi, Buruburu, Lucky Summer and Korogocho all in Eastlands;
Westlands, Kangemi, Uthiru and Kikuyu along Waiyaki Way in the West side of
Nairobi, and Kitengela to the south of the city.
AREA OF STUDY
Nairobi is the largest town in Kenya and also the country’s capital city. It covers
an area of 696 km² and currently has a population of 2,143,254 and population
density 3,079 per square kilometre (GoK, 2000).
At 1.5 0
south of the equator, Nairobi is a tropical city. Its altitude of 5,000 to
6,000 feet means that the climate is temperate. Rainfall is divided between two
rainy seasons: the short rains fall in November and early December, and the long
rains between April and mid-June. Because it is virtually on the equator, Nairobi
has a constant twelve hours of daylight per day all year round. The sun rises at
6.30 - 7.00a.m and sets again at 6.30 - 7.00 p.m.
13. 7
The average day-time temperature varies only slightly throughout the year,
ranging from 85°F (29°C) in the dry season to 75°F (24°C) during the rest of the
year. At night, however, temperatures can drop to as low as 48°F (9°C), though
rarely lower.
Founded as a last halt before the Highlands for railway engineers in the early
1900s, Nairobi, which was then just a few shacks and tracks, now covers 696
square kilometres. This figure includes 120 square kilometres of the Nairobi
Game Park and all of Jomo Kenyatta International Airport. Central Nairobi barely
makes up five square kilometres.
LITERATURE REVIEW
Tangri (2003), notes that despite intensive scrutiny over many years, much
remains unknown about the releases of pollutants from waste-burning activities.
Waste burning produces hundreds of distinct hazardous by-products of which
only a handful of them have been studied thoroughly. Hundreds remain
unidentified. Connett (1998) identifies some of the toxic emissions of incineration.
These include: hydrogen chloride, nitric oxide, heavy metals, dioxins, furans and
other U-POPs, fly ash, bottom ash, stack gas, fugitive emissions plus other
residues.
Polythene bags and plastics, including PVC items, make up approximately 225
tonnes out of the 2000 tonnes of solid waste generated daily in Nairobi (KAM,
2003). This represents about 11% of total waste generated daily, while 75%
comprises biodegradable waste that can be composted. The remaining
percentage is made up of other recyclable materials such as textiles, metal and
glass making up 2.7%, 2.6% and 2.3% respectively. Open burning of municipal
waste is widely used by the residents of Nairobi, as a means of disposing solid
waste.
The following facts regarding plastics were identified from literature:
• According to KAM, consumers and end users are the ones who cause
environmental pollution from plastics;
• Not all plastics emanate from the local industry, some is imported;
• The plastics sector currently constitutes approximately 150 industries, and
has an annual growth rate of 6%;
• Currently, there are about 70 firms that recycle plastics locally; and
• Plastics contribute 28% of all cadmium found in municipal solid waste and
approximately 32% of all lead; substances that are highly toxic to humans
and the environment in general.

Health Effects
Because of the persistent and bio-accumulative nature of dioxins and furans,
these chemicals exist throughout the environment. Human exposure is mainly
through consumption of fatty foods, such as milk. USEPA (2000) in Tangri (2003)
notes that 90-95% of human exposure to dioxins is from food, particularly meat
and dairy products. This is because dioxins accumulate in fats and oils3
. Their
health effects depend on a variety of factors, including the level of exposure,
duration of exposure and stage of life during exposure.
Some of the probable health effects of dioxins and furans include the
development of cancer, immune system suppression, reproductive and
developmental complications, endocrine disruption (GAIA, 2003; Connett, 1998;
Luscombe and Costner, 2003). The International Agency for Research on
Cancer (IARC) has identified 2,3,7,8 – TCDD as the most toxic of all dioxin
compounds.
Environmental and Socio-economic Effects
The accumulation of dioxins and furans in the environment owing to waste
incineration activities can reach levels that render resources unfit for human
consumption. Connett (1989), cited in Connett (2003), reports of an incident in
Netherlands where 16 dairy farmers downwind of a huge incinerator in
Rotterdam could not sell their milk because it contained three times higher dioxin
levels than anywhere else in Netherlands.
Even low doses of dioxins are very toxic. In 1998, the WHO lowered its
recommended Tolerable Daily Intake (TDI) of dioxins from 10 picograms TEQ
per kilogram of bodyweight per day (pg/kg/day) to a range of 1-4 pg/kg/day (Van
Leeuwen and Younes 1998). According to studies conducted in Netherlands,
prenatal exposure to typical daily intake of dioxins and PCBs has effects on
neurodevelopment and thyroid hormones. Deficits of up to four points in IQ and
increased susceptibility to infections in 42 month old children exposed to typical
daily intakes of dioxins/PCBs were observed (Patandin 1999).
Incineration produces residues that require treatment and/or disposal, most often
in a landfill. Incinerator ash - either as bottom ash or fly ash – is highly toxic.
Tangri (2003) observes that handling of this ash raises serious concerns
because workers are often exposed to the ash, sometimes with little or no
protective gear.
In India just like in Kenya, Toxic Link (2000), notes that incineration is
rudimentary and most incinerators are single chambered with a smoke stack.
Major reasons for dioxin emissions from such waste incinerators are:
3
WHO (1999) points out that dioxins are highly persistent for they breakdown very slowly and have a half-
life in human body of about 7 years.
15. 9
• almost all of them burn mixed waste;
• due to lack of enforcement and monitoring, most of the hospitals are
incinerating their plastic waste and also waste treated with chlorinated
disinfectant;
• many of the incinerators still have single chambers, in spite of the fact that the
installation of double (secondary) chambers is needed to eliminate volatile
substances by better combustion; and
• most of the incinerators do not operate under stipulated temperature. Under
the regulations, primary chambers should operate at 850º C and secondary
chambers should operate at 1000º C or more.
Tangri (2003) has enumerated several problems particular to transferring
incineration technology to the developing countries. These problems include:
• lack of monitoring - no ability to regularly monitor stack emissions or
incinerator ash toxicity;
• lack of technical capacity to test releases - not able to conduct tests for
dioxins and other pollutants;
• lack of secure landfills for ash - toxic incinerator ash dumped in, at best,
an unlined pit, where it runs the risk of contaminating groundwater. Access
to the ash land not controlled;
• corruption4
;
• shortage of trained personnel - necessary number of trained Manpower to
manage incinerator operations;
• budgetary constraints - hinder maintenance and replacement of key
incinerator functions; and
• differing physical conditions and lack of robustness of technology - where
incinerator technology imported from the west is not appropriate to the
Southern conditions.
Other Pollutants from Incineration
In addition to dioxins, polychlorinated biphenyls (PCBs) and Hexachlorobenzene
(HCB), incinerators are sources of other halogenated organic compounds, toxic
metals and greenhouse gases to name but a few5
. Toxic metals released from
incineration activities include: Mercury, Lead, Cadmium, Arsenic, Chromium,
Beryllium, Antimony, and Manganese. Stanners and Bourdeau (1995), cited in
Tangri (2003), give a worldwide atmospheric emissions estimate of trace metals
from waste incineration; this is summarized in the Table 1 below:

Where there is corruption the likelihood of installing substandard equipment for kickbacks is high.

Public Opposition to Incineration
Waste incineration is unpopular in many countries. In the USA, for example,
since 1985, over 300 trash incinerator proposals have been defeated or put on
hold due to public opposition, and several large engineering firms have pulled out
of the incinerator business altogether (Connett 1998). In Michigan, all but one of
the 290 medical waste incinerators in the state closed down rather than attempt
to meet federal emissions limits imposed in 1997 (Tangri 2003). Tangri (2003)
reports that in 2001 alone, major incinerator proposals were defeated by public
opposition in France, Haiti, Ireland, Poland, South Africa, Thailand, UK,
Venezuela.
Even in poor countries such as Bangladesh, public opposition to incinerators has
yielded changes. A proposal by an American company to build a power station
which would burn trash shipped-in from New York City to Khulna in Bangladesh
was defeated by public opposition (Connett 1998). In 2000, GAIA was launched.
GAIA members work both against incineration and for the implementation of
alternatives Tangri (2003).
Kenya Eggs Study
A study in early 2005 on egg-sampling by ENVILEAD and Arnika (under the
Dioxin, PCBs and Waste Working Group of IPEN) found eggs collected around
the Dandora dumpsite in Nairobi, Kenya, to have dioxin levels over 6 times
higher than the EU dioxins limits for eggs. In addition, the sampled eggs
17. 11
exceeded the proposed WHO limits for PCBs by more than 4-fold (Fig. 2). It is
estimated that the Dandora open dumpsite handles 803,000 tons of waste per
year (National inventory of POPs, 2004).

STUDY FINDINGS
Basic Findings
The study made several basic findings that will be important in the search for
waste management solutions in Nairobi and elsewhere in the country. Among
these are:
a. The nature of consumer demand: In the Kenyan market, where more than
half the nation’s population lives below the poverty line, plastic constitutes a
very attractive option as the material of choice for numerous domestic,
medical and industrial products. The business organizations that researchers
were able to visit, such as supermarkets and plastics’ manufacturers,
confirmed cost attractiveness of plastic to local consumers. There is therefore
a basic market-based challenge to the problem of waste management,
18. 12
comprising rational economic action linking consumers, manufacturers and
traders.
b. Legal framework and administrative capacity: Waste is a necessary
outcome of any production and consumption process. But in the real world,
the quantity of waste a society produces has implications on the resources
the society requires for managing the same. It is therefore necessary,
especially where resources for waste management are very limited, to
institute measures that reduce the overall quantity of waste generated, with a
special focus on products such as plastics that are especially problematic in
safe disposal.
Proper waste management requires enforcement of the existing legal
provisions. The study established that Kenya has a sound legal framework
(EMCA, 1999) for guiding the utilization of BEP and BAP in waste
management. However, the law is not enforced to the letter. It was
established that most health institutions, including KNH, do only rudimentary
segregation of waste. Of the hospitals visited, only Nairobi Hospital and Mater
Hospital had a thorough waste segregation system.
The existence of suitable legal guidelines is however only one part of the
requirements for a proper system of waste management. The other part has
to do with administrative capacity to enforce such law. The study established
that the City Council, which has the legal responsibility for managing solid
waste in the city, has an alarming lack of administrative capacity for this role.
For example, the Dandora dumpsite, which is supposed to be under the
management of the Council, is a veritable health and ecological time-bomb
for Nairobi and its environs.
General Findings
The following were the study’s general findings:
I. The level of public awareness on the adverse effects of waste burning
activities and U-POPs among the residents is pathetically low. A majority
of the study’s respondents could not link any ill-health to incineration
activities and U-POPs as a major health threat;
II. All the main health institutions in Nairobi such as KNH, Nairobi Hospital,
Mater Hospital, and Forces Memorial Hospital either have their own
incinerators or hire the services of one. In addition however some of the
institutions are involved in open air burning. For instance, the biggest
hospital in Kenya (KNH) burns some of its waste mostly consisting paper,
plastics, clothing etc – usually considered to be of low risk - in an open pit
in front of the incinerator;
19. 13
III. Open burning of municipal waste is widely used by the residents of
Nairobi, as a means of disposing solid waste. In a survey of two blocks’
area around Pumwani in Eastlands, Nairobi, eight small open air waste
burning sites were counted, all of which had assorted plastics;
IV. The incinerator at Kenyatta National Hospital, which is situated just a few
metres upwind from the residential homes of low cadre staff of the hospital
and medical students’ hostels, operates at temperatures between 350°C
and 650°C and has no APCD. The incinerator emits noxious fumes that
are carried to the homes and hostels, causing considerable distress to the
residents;
Plate: Kenyatta National Hospital open dumpsite:
At the background are hospital staff quarters
V. The dioxin-rich bottom ash from incinerators around Nairobi is normally
deposited at the Dandora dumpsite;
VI. The Dandora dumpsite constitutes the most prominent, and challenging,
manifestation of problems arising out of the waste-burning pattern of
practice in Nairobi;
VII. The level of waste recovery, reuse and recycling is grossly inadequate.
For example, only 1% of plastics are recycled (KAM, 2003);
VIII. The legal framework regulating waste burning activities is sound.
However, the enforcement of the law is weak; and
IX. The Nairobi City Council lacks the capacity to manage the waste
generated in the city effectively;
Table 2 below shows a number of major companies in Nairobi that dump their
mixed waste in Dandora dumpsite. It is therefore necessary for the private sector
to be involved in the search for waste management solutions as they are major
contributors of waste.

Findings on Health Effects and Exposure Pathways
The study was not able to carry out a comprehensive investigation into the health
consequences of the incinerators and open air burning sites visited. There were
however complaints about chest complications and serious smoke irritation for
those living downwind from the KNH incinerator, as well as from those living
around the Dandora dumpsite.
The main exposure pathways for any contamination from the sites visited in the
study are:
• Inhalation of the pollutants-infested smoke and fly ash carried across by the
wind;
• Consumption of animal products such as meat, milk and eggs from animals
feeding within and around the sites;
• River water from a river flowing next to the Dandora dumpsite and serving
numerous people downstream on its way to the Indian ocean; and
• Ground water reserves affected by leachate from the Dandora dumpsite.
It is worth noting that some categories of people are at higher risks of exposure
to dioxins than others. These include children, infants, some workers, people
21. 15
who eat fish as a main staple of their diet and people who live near dioxin release
sites. CHEJ (1999) observes that these groups are likely to be exposed to at
least 10 times as much dioxin as the general population.
CHALLENGES TO THE STOCKHOLM CONVENTION:
RESPONSIBLE PARTIES - KENYA
POPs and Scientific Development
The existence of POPs worldwide is one of the best illustrations of the
Frankenstein nature of scientific and technological development. While progress
in science and technology has greatly increased humanity’s power to modify its
environment for its benefit in ways previously unimagined, the same progress
has created threats of similar magnitude to humanity and the planet as a whole.
The last century has been called an “era of chemicals”, where more than 18
million chemicals were synthesized and about 100,000 of them came into
commercial use (Toxics Link 2000).
It was not until the publication of Rachel Carson’s book, “The Silent Spring”, that
the general public’s attention was drawn to the dark side of the chemical
revolution. The Stockholm Convention is in many respects an effort to interpret
Carson’s thesis into social action. The broader framework of the Stockholm
Convention’s objectives should be viewed as completing the loop of knowledge
in chemistry, through developing the institutional capacity to control the real and
potential danger of chemicals. The realization of the Stockholm Convention’s
mandate would be the coming of age of the chemical revolution. As Isaac Asimov
put it, “The saddest aspect of life right now is that science gathers knowledge
faster than society gathers wisdom.”
POPs and Less Organized Countries
The above-outlined problems are relevant to Kenya and other Less Organized
Countries (LOCs). In addition though, LOCs face several challenges that are
unique to their special circumstances. Among these is the sheer pressure of
survival priorities.
The immediacy of hunger, debilitating disease, social and economic dislocation,
and other such concerns that affect large sections of society in LOCs is such that
an issue like that of POPs is unlikely to find a place at the fore of the national
agenda.
The psychological environment of desperate social and economic circumstances
has a tendency to promote fatalism and other behavioural tendencies that are not
conducive to organized long term action based on people’s faith in their ability to
22. 16
influence the course of their destiny. A good illustration of this is the challenge
that the behaviour-change message in the HIV/Aids campaign in Africa has
faced, despite the powerful and very public nature of the AIDS pandemic.
Galvanizing community action for the POPs eradication campaign shall require
very well thought-out strategies, and competent leadership.
In addition to the problem of priorities, LOCs face a big challenge of
organizational capacity in the campaign against POPs. The low levels of
organizational capacity in LOCs translate to challenges in administrative
competence, financial resources, technological resources, monitoring ability and
other such key requirements for an effective POPs eradication campaign.
With sufficient support there are specific organizations within LOCs that can
make a real and positive difference in such a campaign. In the long run, in order
for any major campaign such as that of the Stockholm Convention to be truly
successful, the campaign has to be done in the context of an overall sustainable
development strategy. Such a campaign would have implications going beyond
specific issue of POPs.
For example, a successful POPs
elimination campaign may need
to involve fundamental changes
in the agricultural sector, waste
management approaches and
legislation (as well as
enforcement mechanisms)
dealing with chemical safety in
general. Such an agenda
requires very considerable
organizational capacity both
within the public sector and civil
society, which is the big
challenge for LOCs.
The crippling nature of incinerator debt.
Capital costs of incinerator projects for
instance, drain the resources of LOCs and
increase their indebtedness through the
need for foreign financing to build and
maintain such facilities not forgetting
continued reliance on manufactured
products from other nations. Instead of
allowing nations to develop new industries
and reduce foreign imports, incinerators
transform these resources into smoke and
ash.
Analysis by a local environmental group in
Miljoteknik Zychlin, Poland revealed that
the debt for the US$5million proposed
incineration facility would have taken the
community of 14,000 residents over 100
years to repay! - Brenda Platt (2004)
23. 17
The Environment and Economy
While the growth of science and technology has an important bearing on the
dangers to the environment that the Stockholm Convention and similar other
Conventions seek to counter, it is the market economy that provides the
framework within which the power of science and technology can be projected
into the world.
As is the case with science, measuring economic development in a one-
dimensional manner, purely in terms of (monetary) returns on investment and not
the overall impact of the concerned economic activity on society and the natural
environment, is unsatisfactory. In economics, problems arising from the
undesirable consequences of economic activity that are not captured in the
pricing structure of products are called negative externalities.
Negative externalities are those situations arising from economic activity that
create costs to the society that are not reflected in the balance sheets of the
concerned businesses. For example, in pricing its products, a given organization
may include the cost of labour, energy, marketing, finance and other such inputs
but leave out the cost (borne by the society) of medical and other costs directly
attributable to harmful effects of the organization’s products.
POPs ought to be treated as an aspect of the problem of externalities in
economic theory, and solutions sought within the framework of approaches
developed in the discipline of economics to deal with this problem.
ALTERNATIVE PRACTICES
Other than incineration, landfilling and composting are alternative methods of
waste disposal used in the country, although to a minimal extent. More often than
not, individuals and community-based organizations (CBOs) are the ones
involved in composting biodegradable waste mostly on a commercial basis.
Landfilling is commonly practiced in the smaller health facilities such as District
hospitals, health centers and clinics, but most of these landfills are not built to
standard. Other landfills in the country are situated in Mombasa and Nakuru for
municipal waste disposal, built through the assistance of Agence Francaise de
Développement (AFD), a French operation that works through the government.
Alternative Technologies for Hazardous Waste Treatment
In developed countries, non-incineration technologies for hazardous waste
treatment are available; these include several processes summarized by Crowe
and Schade (2002) in Tangri (2003) in Table 3.

in Kenya.
RECOMMENDATIONS
The study proposes the following measures:
I. Additional studies should be undertaken to acquire additional and more
detailed information about the waste burning and incineration and its
consequences in Kenya. This includes analysis and quantification of U-
POPs in biotic and abiotic systems and their impact on public health;
II. In line with Article 10 of the Stockholm Convention, Public information,
awareness and education on U-POPs should be carried out, for a well
informed citizenry will make a big contribution on efforts geared towards
elimination/ and reduction of the U-POPs. Proper education and training
in waste management must be offered to all stakeholders in a way best
suites their respective circumstances and builds their understanding and
changes their behaviour accordingly;
III. Subsidiary legislation addressing waste incineration should be enacted
under the Environmental Management and Coordination Act (1999). This
should guard against indiscriminate burning of waste;
IV. A buy-back scheme for used plastics should be instituted. This should not
be difficult to do because the plastics industry is willing to manage waste
sites in all major population areas where the manufacturers will buy plastic
waste from the general public. Such collection centres would be set up
and fully funded by the same manufacturers (KAM, 2003);
V. A national campaign, financed by the plastics industry should be
launched, giving the public exact details of where to take their plastic
waste for recycling. Supermarket chains should also be encouraged to
allocate bins in their branches where customers can bring back plastic
carrier bags and other items for recycling;
VI. A zero waste program should be introduced immediately and eventually
developed into policy. It has been tried and tested in other countries and it
is rapidly gaining acceptance the world over. Within the zero waste
program, there should be a rigorous national campaign lobbying for an
end to open burning and incineration of waste and in particular waste that
contains PVC;
VII. Waste segregation at source should be the standard practice in all
households and medical facilities. The current waste management
practice in which waste materials are all mixed together as they are
generated, collected, transported and finally disposed of should be
stopped. If proper segregation is achieved through training, clear
standards, and tough enforcement, then resources can be turned to the
26. 20
management of the small portion of the waste stream needing special
treatment6
;
VIII. A policy of Extended Producer Responsibility (EPR) should be put in
place. The basic concept of EPR is that firms must take responsibility for
their products over their entire life cycles (Tangri 2003). This is in harmony
with the “Polluter Pays” principle of the Stockholm Convention;
IX. Statutory regulations to force manufacturers to use at least 15% recycled
plastics in their non-food products should be imposed. In this way demand
for plastic waste will be created therefore leaving little if anything for
disposal. Since to install capacity for recycling is expensive however, the
plastics’ industry should be given tax incentives for the exercise;
X. Cleaner production based on a circular vision of the economy should be
encouraged. Cleaner production aims at eliminating toxic wastes and
inputs by designing products and manufacturing processes in harmony
with natural ecological cycles (Tangri 2003);
XI. Product bans ought to be made for certain categories of manufactures.
Products and packaging that create waste problems (non-recyclable or
hazardous- such as polyvinyl chloride - PVC) for the society should not be
allowed to enter into the economy. Bans are appropriate for materials that
are problematic at every stage of their lifecycles (Ryder 2000 in Tangri
2003);
XII. Infrastructure for the safe disposal and recycling of hazardous materials
and municipal solid waste should be developed. Approximately 50% of all
waste is organic, and can therefore be composted. Another large segment
of the remainder can be recycled, leaving only a small portion to be
disposed. The remaining portion can then be disposed through sanitary
landfills, sewage treatment plants, and other technologies.
To ensure continuity and clarity in the proposed recommendations, clear plans
and policies on management and disposal of waste should be developed. This
should be followed by integrating them into routine workers’ training, continuing
education and evaluation processes for systems and personnel. Involvement of
all stakeholders including public interest NGOs and other civil society in
developing and implementing a waste management scheme is necessary for
successful implementation of the Stockholm Convention.

Platt and Seldman (2000), show how comprehensive waste composting, reuse and recycling
programmes generate ten times as many jobs per tonne of municipal waste as do incinerators.

CONCLUSION
The burning of waste as a method of waste disposal in Nairobi clearly constitutes
a pattern of practice which contributes to the release of U-POPs into the
environment. As suggested by the term “pattern”, this practice is a complex
process involving economic factors, people’s attitudes, governance issues and
other such components. It is a matter requiring detailed study and much creative
effort to address satisfactorily.
In its broader context, the issue of waste management is an aspect of the
challenge of sustainable development. Inability to deal with waste in such a way
as it does not harm people or the environment is an indication of an ecologically
unsustainable system of social organization. The challenge of sustainable
development is to design an economic and technological system that is in
harmony with ecological principles.
The current dominant system of economic and technological organization in the
world is powerful and in many respects very successful. It is however not a
sustainable system and in fact constitutes a veritable danger to the survival of life
in the planet. There is need to review some of the system’s most basic
organizational principles, as a way out of the dangerous trajectory it has set for
humanity.
The poorly formed social structures and systems in LOCs, especially in sub-
Saharan Africa, may ironically make the best hope for the development of fresh,
ecologically sustainable development approaches. LOCs have the opportunity to
build their houses with the special benefit of a wealth of knowledge of the
successes, and follies, of the past. LOCs should proceed to build their societies
with energy and enthusiasm, but with the clear understanding that humanity
cannot stand outside, or above, the ecological order that sustains all other life in
the planet.
