The document discusses persistent organic pollutants (POPs) in Rwanda. It finds that awareness of POPs and their effects is low, resulting in continued POPs use. The most common POPs in Rwanda are organochlorine pesticides, polychlorinated biphenyls, and dioxins and furans as unintentional byproducts. Studies identified POP pesticides stored at dumps and estimated levels of PBDEs in electronics. Exposure to POPs poses risks for waste workers and communities near contaminated sites. The paper aims to characterize POPs and build capacity for sound management to transform wastes into resources.
A good environment they say predetermines good health. If good health is to be measured at all the people and the environment will play a significant role. Illness and disease however, do not exist in isolation of the environment in particular. Waste is an object for which we have no further use and which has to be disposed off because of the danger it poses to the environment. Solid waste refers to garbage, refuse, rubbish, trash or litter generated through the domestic, commercial and industrial activities of man. As the population increased efforts were made to transport waste out of the cities. This study therefore examined the problems of solid waste disposal in Ibarapa East Local Government Area of Oyo state. Two hundred respondents were sampled from the study area. The major instruments of data collection were questionnaire administration, personal observation and oral interview Data were analyzed using cross tabulation and simple percentage The findings shows that the respondents were aware of effects that improper solid waste to have in their environment and health but still indulge in insanitary wasted disposal. Also the role of Government in waste disposal was below normal standard. It was recommended that the people should change their unsanitary system of waste disposal and government should improve on waste disposal policy.

Abstract: Solid waste disposal remains one of the major challenges of urbanization in developed and developing countries. The sanitary state of an area, particularly the sub-urban areas is influenced by waste handling practices by the residents and the measures put in place for safe waste collection and disposal. The objective of this study was to assess disposal mechanisms of solid waste among households in Kaptembwa location in Nakuru West Sub-County. The research adopted social inquiry design where a structured questionnaire was administered to household heads, oral interviews and focus group discussions were also conducted. The unit of analysis was the household selected in four estates. The study population was 400 households and a sample size of 200 households. The selection of the household units for data collection was based on simple random sampling. The data was analyzed using the Statistical Package for the Social Sciences (SPSS) computer software (version 17) and results presented by descriptive statistics (graphs and tables). Inferential statistics was also used to show the relationships between independent and dependent variables. The findings and recommendations of this study provide information not only to the Kaptembwa residents but also residents living in low income of urban and peri-urban areas to adopt best practices in solid waste management to improve environmental quality and enhance the health status by reducing the incidence of disease outbreaks. This can be achieved by the implementation of some key research recommendations which includes use of smart shopping to avoid the excess use of polythene bags, proper sorting and storage of waste, using improvised storage receptacles such as disposable cartons and dust bins as well as engaging the Community Based Organization (CBO) dealing with waste collection, transportation and disposal.

The rapid population growth, and rise in community living standards has been a major contributor to generation rate of municipal solid waste. Managing it has been a major challenge worldwide. This study examines the waste management activities of Borno State Environmental Protection Agency (BOSEPA). The study utilizes simple descriptive statistics including tables, frequencies and percentages for data analyses. The results indicated that most waste generated is from domestic activities with 69%. Majority of the respondents constituting 45% pointed garbage as the type of waste generated and the results also indicated that majority of the respondents are using plastic containers representing about 43%, while 42% of the respondents disposed waste openly. With respect to the expectation of BOSEPA, 48% admitted that regular collection of refuse is not carried out by BOSEPA as expected. The study concludes that the metropolis is lacking waste collection points, collection containers and the respondents hardly see BOSEPA staff in the available collection points for refuse collection.

Solid Waste Management in Lebanon: Challenges and RecommendationsPremier Publishers
Successful waste management plans require accurate data about the nature and composition of waste. Despite the high content of organic (52%) and recyclable (37 %) materials in waste stream, only 8% and 15% of solid waste are recycled and composted respectively. Unfortunately, 48% of the waste are disposed in sanitary landfills. Dumping of waste and open burning is predominant outside Beirut and Mount Lebanon. Adequate treatment is unavailable for wastes produced by slaughterhouses, industrial premises and healthcare centers. Corruption, lack of human resources and suitable facilities and inadequate technical skills are responsible for inefficient municipal solid waste management. This paper aims at determining the current practices of municipalities in terms of segregation, collection, treatment and final disposal of solid waste. It also considers key policy challenges and recommendations for improving the municipal solid waste management system.
This document discusses waste management practices around the world. It begins by defining different types of waste and methods of waste classification. The main types discussed are solid, liquid, sludge, and hazardous wastes. It then compares waste management approaches between developed and developing countries. Developed countries generally have more advanced waste disposal systems like sanitary landfills and waste-to-energy incineration, while developing countries rely more on open dumping. The document also provides details on solid and liquid waste management systems in the Philippines.
This document discusses hazardous waste and its management. It defines hazardous waste as any waste that poses a danger to health or the environment due to its physical, chemical or toxic properties. It notes that heavy metals like lead and mercury, as well as synthetic organics, persist in the environment. The document outlines rules for hazardous waste management and lists various hazardous waste constituents and their concentration limits to determine appropriate handling.
Domestic waste is waste produced from household activities that is disposed of through regular trash collection. It includes everyday discarded items. Hazardous domestic waste contains dangerous materials like solvents, paints, pesticides, batteries, and electronics. Improper handling and disposal of hazardous waste can pollute the environment and harm human health through toxic gas release or groundwater contamination. The effects of untreated hazardous domestic waste include nervous system issues from mercury vapour inhalation and possible home explosions from methane build-up near landfills. Responsible waste management is important with the earth's resources already over-burdened.
This document analyzes the environmental and economic impacts of local agricultural production compared to imports for various crops in Israel using life cycle assessment. The study finds that:
- For apples and onions, local production has lower environmental impacts than imports. However, for almonds and potatoes, imports have lower impacts than local production which relies heavily on chemicals.
- The main environmental damages for both local production and imports are impacts on human health from inorganic chemicals and climate change, as well as depletion of natural resources.
- An economic analysis finds that local production has a higher economic value than imports for some crops like pears and almonds when considering profits, scenic value, and avoided environmental impacts of imports.

Waste management continues to be a critical environmental issue in cities. It impacts on the well being of the population, the environment and the biodiversity. In the city of Maradi, in Niger, more interest is given to the problem in order to understand the whole waste management system. It is in this context that this study is carried out to investigate on the role of ruderal flora on the municipal solid wastes dumpsites and landfill sites in Maradi city. The specific objectives are to determine the floristic diversity and distribution of ruderal flora on the municipal solid waste disposal sites, and to identify potential species that can play an important role in the phytoremediation of these sites. In total, 65 species belonging to 52 genera and 24 families were recorded. These species can be categorised into two groups containing anthropic and nitrophilic species according to the ascending Hierarchical Classification (AHC) at 25% similarity. Characteristic species of the first group G1 are Amaranthus viridis and Cucurbita pepo, and Datura innoxia and Cucumis melo for the second group G2. Other ruderal species, namely Amaranthus spinosus L., Amaranthus viridis L., Celosia trygina L., Datura innoxia Mill., and an introduced woody species, Cuphea hyssopifolia Kunth., found are not included in the Maradi city list of species. Datura innoxia, Amaranthus viridis and Amaranthus spinosus are species known to tolerate different degrees of pollution and their ecology should be further study to better understand how they can be used for phytoremediation on this kind of sites.

Species diversity and distribution of ruderal flora on landfills in Maradi ci...IJEAB
Waste management continues to be a critical environmental issue in cities. It impacts on the well being of the population, the environment and the biodiversity. In the city of Maradi, in Niger, more interest is given to the problem in order to understand the whole waste management system. It is in this context that this study is carried out to investigate on the role of ruderal flora on the municipal solid wastes dumpsites and landfill sites in Maradi city. The specific objectives are to determine the floristic diversity and distribution of ruderal flora on the municipal solid waste disposal sites, and to identify potential species that can play an important role in the phytoremediation of these sites. In total, 65 species belonging to 52 genera and 24 families were recorded. These species can be categorised into two groups containing anthropic and nitrophilic species according to the ascending Hierarchical Classification (AHC) at 25% similarity. Characteristic species of the first group G1 are Amaranthus viridis and Cucurbita pepo, and Datura innoxia and Cucumis melo for the second group G2. Other ruderal species, namely Amaranthus spinosus L., Amaranthus viridis L., Celosia trygina L., Datura innoxia Mill., and an introduced woody species, Cuphea hyssopifolia Kunth., found are not included in the Maradi city list of species. Datura innoxia, Amaranthus viridis and Amaranthus spinosus are species known to tolerate different degrees of pollution and their ecology should be further study to better understand how they can be used for phytoremediation on this kind of sites.

Factors Affecting Solid Waste Management in Kapchorwa Town Council, Kapchorwa...PUBLISHERJOURNAL
The problem of Solid Waste Management (SWM) has become a major problem in the upper areas of developing countries. In Uganda, the menace of urban waste has further been worsened by the increasing population. This study was done to assess the level of knowledge and practices about SWM within the Kapchorwa Town Council (KTC) Kapchorwa district in eastern Uganda. To achieve the objectives, a descriptive cross-sectional study was carried out and waste characteristics, collection, disposal, stakeholder roles, and waste management responsibilities were analyzed. Results indicate that waste is predominantly biodegradable (66%) and generated mainly within households, with no proper collection rate disposed of, crude dumping was the major means of disposal used (72.5%). The council is under capacity to handle waste management demands and their services are poor or nonexistent which has led to the use of crude dumping which has risk health. The strategy for solid waste management is failing because the community members are not cooperative. In conclusion, waste management practices in KTC are poor and they reflect a gap in knowledge about effective waste management within KTC, community members should be regularly educated on the link between improper solid waste management and disease outbreaks and the safe SWM practices such as reuse and recycling.

environmental impact evaluation of the industry of panela by life cycle analysisIJEAB
The objective of the study is to evaluate the environmental impacts generated by the industry of the panela in Ecuador, using the Life Cycle Analysis methodology. The in situ information gathered allowed the identification of the sensitive environmental factors that are affected in all the operations that are carried out in the agroindustry of panela. The results show that the craft activities prevail rather than the industrial activities, due to the low industrial development, application and control of regulations, rudimentary manufacturing practices, among others; which have led to insufficient productivity, competitiveness, quality and safety of their products. The results of the Environmental Impact Assessment, using the Eco-Indicator 99 method, according to the Life Cycle Analysis technique, show that the industrial stage has the greatest contribution to the impact, being more representative the impact to the effects by respiration of inorganic compounds, acidification / eutrophication, climate change and land use. The impact level of this type of industry according to Ecuador's environmental legislation, places it as an industry that generates moderate environmental impacts, it does not require intensive protective or corrective practices. However, it requires environmental executive actions oriented to the control and prevention to mitigate these impacts.
In the sense of landfill management, the general premise of pretreatment technologies is that treating the waste before final disposal will reduce the volume of waste being landfilled and enhance or accelerate the stabilization of the waste, reducing the long-term disadvantageous effects on the environment.

Climate Change and Solid Waste Management.pptxdicefredeluces
Solid waste refers to unwanted materials that are discarded and arise from human and animal activity. Solid waste is generated from residential, commercial, and industrial areas and must be managed in various ways. In Olongapo City in the Philippines, an average of 250-300 tons of garbage are collected every day. Solid waste management aims to reduce health and environmental impacts of waste in an efficient and cost-effective manner through activities like waste collection, transport, processing, and disposal. Poor solid waste management can lead to environmental pollution, health issues, and financial burdens for communities.

IRJET- A Comprehensive Study of Solid Waste Management in Mangalore City-Case...IRJET Journal
This document summarizes a study on solid waste management in Mangalore City, India. It finds that Mangalore generates approximately 226 tons of solid waste per day, with per capita waste generation of 0.4524 kg per day and household per capita generation of 0.2095 kg per day. Though generation levels are not alarming, waste management practices need improvement. Currently there is some segregation, door-to-door collection, and processing via windrow composting and vermicomposting. However, most waste is ultimately landfilled. The study calls for better segregation, collection, and use of decentralized waste-to-energy technologies to reduce burden on landfills and improve sustainability of Mangalore's solid waste

1.0 Abstract
Based on research, products have changed over the years from being reusable to being disposal. This strategy has influenced negative factors that have greatly affected the environment. The disposal of solid waste products has been the major cause of pollution in the current world. Since the year 1990s, it is evident that millions of people have doubled their output of solid waste to the environment in different ways. Research shows that 75% of waste comes from the mining waste while other 12% comes from agricultural materials. The other 9% is from industries and 4% from municipal waste. In that case, the approach of solid management is very important because it is necessary for safety of human health and environment.
Key words: solid waste management, disposal, recycling, and environmental health.
1.1 Introduction
The issue of solid waste management is a very important approach nowadays. Based on research, it is evident that very little attention is paid to solid waste disposed on landfills. As a result, the environment has faced more than a few issues such as poor health and desertification. This approach has negatively affected the health of more than a few people globally because solid waste has a huge impact to the environment. It is clear that the problem and danger of solid waste is always underestimated by the government and the society at large. Therefore, it important for people to understand the importance of solid waste management because the dangers mainly remain under estimated. Solid waste management plays a pivotal role in the society given the fact that it results in the improvement of the waste management, collection and disposal practices.
1.2 Explanation
As a result of increased cases of solid waste disposal, the government has come up with considerable measures that will ensure that management of solid waste is efficient. A number of people are not aware of the negative effects that these disposals can cause in their lives and the environment as well. As a result of increased issues linked to solid waste, the government should put in place specific planning and cost analysis metrics in an effort to address the waste management menace. One such metric is the adoption of an integrated solid waste management (ISWM) program that forms the basis of the paper.
It is evident that a single waste management strategy is suitable for managing all types of waste in all circumstances. Research shows that most people globally believe that they have done everything eliminate waste such recycling in their homes. However, recycling is not the answer to waste that is disposed in the landfills. The major objective of solid waste management is to ensure that solid waste is eliminated from the environment in order to ensure that environment is conserved properl.

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.
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.
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.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Characterization of Persistent Organic Pollutants (POPs) and its
adverse effects on environment and public health in Rwanda
Mr. Bernardin Bavuge1

, Dr. Abias Mbonigaba3
Expert in Environment & Climate Change
Abstract— There is a low awareness level among the general populace and relevant stakeholders on Persistent Organic
Pollutants (POPs) and their adverse effects on human health and the environment. This often results in the continued use of
POPs in agriculture as pesticides, industrial chemicals, and production of unintentional POPs from incineration, open
burning, and other practices that add to the POPs level in Rwanda. Thus, all stakeholders have a responsibility in the
process but due to the lack of awareness about the issue they are not able to fulfill this role. With increased awareness,
concrete steps can be taken towards the elimination of POPs in Rwanda. The identification of the stakeholders and their
roles in the waste management in Rwanda, tool kit for POPs identification and quantification, Desk Review and Field visits
have been used to characterize and assess the management of POPs in Rwanda. The most commonly encountered POPs in
Rwanda, are organochlorine pesticides, industrial chemicals, most notably polychlorinated biphenyls (PCB), as well as
unintentional by-products of many industrial processes, especially polychlorinated dibenzo-p-dioxins (PCDD) and
dibenzofurans (PCDF). The POP pesticides are temporarily stored in the Nyanza-Kicukiro dumpsite. These POPs pesticides
are Endosulfan 3% dust (1,748 kg) and Lindane (mixed with Thiram (Fernasan 45%WP): 1,280 kg. The country contains
around 1,905.9 kg of PBDEs and both transport sector and electronic sector have almost the same contribution as their
contents are around 935.9kg and 966.1 kg respectively. The production of iron and steel from metallic wastes (scraps) are
producing the UPOP releases of 4000 g TEQ/a in air and 6000 g TEQ/a in residues and waste incineration of medical
wastes released 42.1 g TEQ/a in air and 104.6 g TEQ/a in residue. And other sources are producing UPOP releases at low
level. The contaminated sites are Nyanza, Nduba landfill, Nyabugogo wetland and Gikondo industrial Park. The workers
who recycle and dispose of POPs are exposed to dangerous materials and the environment suffers from them. This paper is
intended to characterize the POPs and waste management in Rwanda in order to characterize the persistent organic
pollutants (POPs) and build capacities of vulnerable communities for the sound environmentally management of chemicals
and wastes and transforming waste into resources of greater value for reuse. This paper can be considered as one of primary
form of intervention related to persistent organic pollutants and waste management in Rwanda.
Keywords— Persistent Organic Pollutants (POPs), PCB.
I. INTRODUCTION
1.1 Background
The Republic of Rwanda became a Party to the Stockholm Convention in order to work in liaison with the International
Community in order to tackle problems arising from the Persistent Organic Pollutants (POPs). The Stockholm convention
covers the management of POPs harmful to human and environmental health. The release of POPs is a factor of aggravation
of poverty in developing countries and hinders the governments’ efforts for a sustainable development (Stockholm
Convention, 2009). Persistent Organic Pollutants (POPs) are chemical substances that persist in the environment, bio
accumulate through the food web, and pose a risk of causing adverse effects to human health and the environment (Maren
Mellendorf, UNIDO). This group of priority pollutants consists of pesticides, industrial chemicals (such as PCBs) and
unintentional by-products of industrial processes like dioxins and furans (UNEP, 2011).
In addition to their toxicity, POPs are Persistent chemicals in the environment, and do not easily degrade in the environment
(that resist rapid degradation); undergo or travelling long distance globally (transport through air, water and migratory
species across international boundaries far from their place of release); are bio accumulating in people and wildlife; They are

Page | 18
usually fat soluble and build up in higher trophic levels; they accumulate in terrestrial, marine and aquatic ecosystems far
from their origin; as semi-volatile compounds, POPs undergo a series of evaporations and condensations in the environment,
making them mobile.
The national challenge posed by chemicals in agriculture (pesticides & fertilizers) and waste management in Rwanda is
multifaceted, with human health risks associated with it being a key area of concern. The general concern is that Rwanda
might suffer from air, water and soil pollution, food contamination, soil microorganisms decline, vector-borne diseases for
animals and plants/crops, diseases, insect pests and diseases of grains, seeds and crops with higher frequency and greater
intensity. The sound management of chemicals and wastes is an important component of Rwanda’s efforts to achieve
sustainable, inclusive and resilient human development in Rwanda. It’s imperative to advocate for integrating chemicals
management priorities into national environmental and poverty reduction planning frameworks, helps access financial and
technical resources, and provides assistance and implementation support to improve the holistic management of chemicals
and waste at national level.
1.2 Problem justification
There is a low awareness level among the general populace and relevant stakeholders on Persistent Organic Pollutants
(POPs) and their adverse effects on human health and the environment. This often results in the continued use of POPs in
agriculture as pesticides, industrial chemicals, and production of unintentional POPs from incineration, open burning, and
other practices that add to the POPs level in Rwanda. Thus, all stakeholders have a responsibility in the process but due to the
lack of awareness about the issue they are not able to fulfill this role. With increased awareness, concrete steps can be taken
towards the elimination of POPs in Rwanda. The locally generated domestic waste such as municipal wastes, kitchen waste,
medical waste and industrial waste and unintentionally produced chemicals continue to be generated. Also, the capacity is
still limited under both public and private sectors in terms of technology as well as human skills to properly handle and
reduce discharge and/or transfer of waste into more useful resources. However, without sound management practices,
chemicals and their hazardous wastes can pose significant risks to human health and the environment especially for the
poorest members of the local community.
Further, at present, various activities relative to waste management such as waste collection, waste selection and recycling,
and waste dumping are conducted by various entities without having knowledge or skills, techniques and any harmonized
institutional framework. Some activities are done inefficiently and it is missing the chance to maximize reusing and
recycling, and minimize landfill site discharge (Basel Convention, 2003). If left unchecked, this will have adverse impacts on
environment in general and on human health in particular. Therefore, Sound waste management is one of the serious and
pressing environmental issues that the urban areas in Rwanda are now facing. It’s in this framework that this study was
conducted to characterize the persistent organic pollutants (POPs) and build capacities of vulnerable communities through
CBOs to address chemicals and waste management in Rwanda. The public awareness on POPs effects to human health and
the environment will be raised. Safe and proper handling of chemicals and waste management promoted and therefore the
production, use, and/or release of POPs should be reduced or eliminated.
II. MATERIALS AND METHODS
To get the current status of POPs management present in Rwanda different methodological approaches were used:
identification of the stakeholders and their roles in the waste management in Rwanda; tool kit for POPs identification and
quantification; desk Review and field visits.
2.1 Identification of the stakeholders and their roles in the waste management in Rwanda
The identification and analysis of stakeholders was an important step as it allowed to the team to draw out the opportunities
and relationships that can be built on during the implementation of POPs management in Rwanda. The analysis of collected
data also helped to identify who, where and when each group (stakeholders) intervenes.

A desk review of the available reports and documents on POPs management was carried out to assess the status of the POPs
management in Rwanda. One of the key documents reviewed among others is the “National Implementation Plan of the
Stockholm Convention on Persistent Organic Pollutants (POPs) in Rwanda: 2007-2025. Important reports on pesticides
inventory and management have been reviewed. The review of literature also covered reports, publications, the legal, policy
and institutional framework related to POPs management.
2.4 Field visits
The field visits targeted mainly the following key players: Institutions members of the POP steering committee where
appropriate, REMA, Rwanda Revenue Authority, pesticides and veterinary products agro-dealers. The visits were performed
at the stockholders’ workplaces and discussions conducted with the main technician or the owner of the company according
to a short indicative interview guide and the questionnaires have been used to collect data.
III. STUDY AREA
The study covered the sites of Rwanda including the landfills, dumpsites, hospitals located in 30 Districts, 4 provinces and
the City of Kigali. The site visits have been conducted to assess the status of POPs management and wastes in general and
how these affect the waste collectors and local communities.
IV. RESULTS AND DISCUSSIONS
4.1 The case of Rwanda for POPs management
The case of Rwanda considered in this study has shown some of the observations of POP issues including wastes from
hospitals and industries, waste from septic tanks, latrines, manure and animal waste, refuse infest water, electronic waste, air
and soil pollution are the most serious issues that Rwanda is dealing with in order to keep green environment. The workers
collecting waste are extremely vulnerable to POPs accumulation due to the collection, transport, separation and treatment of
wastes without appropriate protection equipment. These people are highly exposed to the POPs releases during waste
incineration. In the cities of Rwanda, waste management is conducted by private corporations. At present, 13 companies
(AGRUNI, COPED, UBUMWE, INZIRA NZIZA, ROAD ENVIRONMENT PROTECTION (REP), CESCO, COCEN,
COVAGAYING, ISUKU KINYINYA, UMURIMO MWIZA, INDATWA, and BAHEZA) are operating in Kigali City.
These companies take care of the collection and transport to the landfill of waste.
4.1.1 POP Pesticides in Rwanda
The analysis of the situation revealed that except dioxins and furans which are unintentional POPs, Rwanda never produced
or reformulated the POP pesticides or industrial products. Pesticides can be found in large amounts on commercial farms.
Some of pesticides may have expired or are no longer used by the farmer and could possibly leak out of their old containers
and drums in which they are stored. It was revealed that in Rwanda, pesticides are used on crops such as coffee, rice, maize,
Irish potatoes and vegetables, against insects that invade crops. Nearly 75% of imported fungicides (Mancozeb + copper
oxychloride) are used on Irish potatoes and coffee and 75% of imported insecticides are applied to coffee and almost all of
herbicides are used in tea plantations (Twagiramungu F., (2009), Environmental, health and safety management of disposing
of unused and expired pesticides and fertilizers on behalf of RSSP / MINAGRI). The ministry of agriculture (MINAGRI) has
banned a number of pesticides including POPs pesticides prohibited on national territory. The unlawful entry of obsolete
pesticides banned can be observed on the borders with Uganda as Thiodan (Endosulfan).
Currently the POP pesticides are temporarily stored in the Nyanza-Kicukiro dumpsite. These POPs pesticides are Endosulfan
3% dust (1,748 kg) and Lindane (mixed with Thiram (Fernasan 45%WP): 1,280 kg (REMA, (2005), National inventory).
Lindane and Endosulfan are mentioned as Toxic Pollutants Substances, and later on they have been listed as POPs by
conference of parties of the Stockholm Convention respectively in May 2009 and May 2011.

4.1.2 POP-PBDEs
The POP-PBDEs in electrical and electronic equipment (EEE) and related waste (WEEE) were founded on the recent
inventory that was conducted by the MINISTRY of ICT that put out the combined mass of EEE in use and WEEE generated
yearly in Rwanda (REMA 2015, National inventory of POPs in Rwanda). The Sources of EEE/WEE observed in Rwanda are
essentially the following: IT & Telecom Equipment, Large Household Appliances, Small Household Appliances, Consumer
& Lighting Equipment, Electrical & Electronic Tools, Toys, Leisure & Sports Equipment, Medical Devices and Monitoring
& Control Instruments. It is considered only the POP-PBDEs in transport sector (cars, jeeps, pickups, trucks and buses) and
in EEE/WEEE as other uses of POP-PBDEs (e.g. furniture, mattresses, textiles, construction materials, rubber, and drilling
operations) are thought to be of minor relevance. The non-relevance in this case of Rwanda is supported by the fact that most
of the industries of this sector started after the ban of the production of PBDEs. In this context, the country contains around
1,905.9 kg of PBDEs and both transport sector and electronic sector have almost the same contribution as their contents are
around 935.9kg and 966.1 kg respectively.

From the table above it is very important to note that, category 2 that concerns the small household appliances EEE or their
wastes is missing as the data were not available during the inventory.
Although the absence of data is a gap in the inventory, even the POP-PBDEs inventory guideline recognizes the non-
relevancy of POP-PBDEs of this category particularly when it arrives at the recalculation of c-Octa BDE concentrations.
However, the management of wastes related to category 2 as well as other wastes is described in a specific chapter. The
estimation of the quantity of POP-PBDEs-c-Octa BDE was done applying the formula earlier given in the previous paragraph. As
the available data show only the quantity of EEE present in Rwanda and the quantity of WEE entering in waste stream
yearly, only these two parameters were considered.

4.1.3 PFOS
Although PFOS and its derivatives are used in numerous manufacturing processes such electronics industries, Semiconductor
industry, Photographic industry, Metal plating industry, chemically driven oil and gas production, mining industry, mining
industry, and in Manufacture of plastic and rubber product; these industries are yet developed in Rwanda. Examples of PFOS
or related substances applied to different consumer articles and products: Textiles and upholstery, synthetic carpets, leather,
paper and paper board, industrial and household cleaning products, surface coating, paint and varnishes, medical devices,
toner and printing inks, cleaning agents, waxes and polishes for cars and floors… The next two tables are showing recent
importation of EEE and E-wastes discharge by 2014.

POP-PBDEs were used in electrical and electronic equipment. The mass flow of these equipment, involves different
stakeholders starting from their manufacturers, importers, users (government and private institutions), refurbishes, wastes
collection companies, regulation institutions, local government, etc. Like in other developing countries the E-wastes
managements in Rwanda needs more works as the lack of the recycling companies as well as appropriate technology hinder
their Environmental Sound Management (ESM).
Old EE collected from governmental institutions are stored at GIKONDO under the supervision of Rwanda Housing
Authority (RHA) which will plan how to auction them. Others are still in store of those institutions. All those e-wastes stored
at GIKONDO are mixed with other waste including waste from office furniture. The visit to different institution either public
or private revealed that E-wastes are stored in specific stores waiting to be auctioned, the practice that end up by handing the
E-wastes and old E-equipment to the refurbishes. The same management practice is found in private sector. According to
COPED, sometimes the e-wastes generated at household are included in other wastes in the wastes collection sites.
4.1.4 Vehicles Wastes from garages and households
Vehicles are concerned as they contain PBDEs and PFOS as mentioned previously. The wastes from vehicles are generally
found in private garages and institutions garages. In different garages across the country, the scraps metals and replaced spare
parts are collected and stored. When the stock is big, Steel Rwanda scraps dealers buy and take them to the plant for
recycling. However, sometimes the clients like to take the replaced spare parts to their homes. Furthermore, in Kigali City
wastes which are not taken to Steel Rwanda Ltd are collected by COPED and end up also by entering in Nduba dumpsite.
Even metals are not containing POPs, the poor sorting of scraps from other parts with plastics as well as their contact with
hydraulic oil make them to be part of items concerned by Stockholm convention.
4.1.5 PCB
4.1.5.1 PCBs in Rwanda
The field visit of equipment was conducted in REG/EUCL and private energy producers’ hydro power plants, transmission
and distribution network, and major industries based on information of equipment. The disposal options were assessed. A
datasheet was used for the identification of the PCB-containing equipment were appropriately filled so that every transformer
can be identified, location, company name or the user, name of the manufacturer, etc. It was carried out for the identification
of the PCB-containing equipment based on information available and collected on the nameplate.

4.1.6 Unintentional –POPs (UPOPs) in Rwanda
The data collected from human activities such as waste incineration of medical, municipal wastes, cement kilns and thermal
processes have been analyzed according to the source categories provided by the toolkit for identification and quantification
of releases of dioxins, furans and other unintentional POPs, under article 5 of the Stockholm convention. The toolkit was
used to calculate all relevant PCDD/PCDF sources. The municipal solid wastes are not incinerated. Some are burned openly
and they release PCDD/PCDF in flue gas, fly ash, bottom ash and wastewater. The municipal solid wastes are generated by
household during normal daily life and it also commonly includes wastes produced in industrial, commercial and agricultural
activities. They are composed of paper and cardboard, plastics, food and kitchen residues, cloth and leather, wood, glass and
metal as well as dirt and other inert materials. Small quantities of hazardous materials, such as batteries, paints, drugs.
According to information gathered from technical services encountered on land, these wastes contain infectious material,
secretions, blood, safety boxes of (syringes, needles, cotton), gloves, saddle pots, buffers, dressing waste, packaging and
chemicals. The incineration of medical wastes is operated in small and poorly controlled incinerator in health centres; this is
a major source of PCDD/PCDF. Currently medical wastes are incinerated at hospital incinerators with two types of furnaces
(main furnace and after burner). The current situation shows that the quantities of medical wastes from hospitals of Rwanda
are 2,911,422 kg per years.

4.2 Production of ferrous and non-ferrous metals
The sub category of Iron and steel production plants is produced in two plants located at Rwamagana (SteelRwa) and
IMANA Steel located at Bugesera/Gashora. Annual production is 400,000,000 tones / year of iron and steel. This activity can
be potential source of PCDD / PCDF as thermal processes contaminated non-ferrous metal scrap influenced by the degree of
using scrap metal contamination and also retention and treatment of gas flow.

FIGURE 1: Production of iron and steel from metallic wastes (scraps)
According to the graphs above the production of iron and steel from metallic wastes (scraps) are producing the UPOP
releases and the second production is waste incineration of medical wastes. And other sources are producing UPOP releases
at low level.
V. THE CONTAMINATED SITES (HOTSPOTS)
5.1 Former public waste dumpsite of Nyanza- Kicukiro
This waste dumpsite is located at the top of the hill called Nyanza Kicukiro, in Kagarama Sector, District of Kicukiro. The
site contains all kind of waste from Kigali town for long time ago up May 2012, the time the town’s wastes were relocated to
the Nduba dumpsite.
5.2 Public waste dumpsite of Nduba
This public waste dumpsite located in Nduba Sector, Gasabo District; has replaced the Nyanza-Kicukiro site in May 2012.
The site receives all kind of urban waste without a prior sorting. The dumpsite receives an average of 70 trucks (5 tones /
truck) per day. Nduba dumpsite was initially designed for receiving in general all kinds of wastes segregated at the origin in
order to allow an easy recycling process for some of them. Since this site was opened, no infrastructure development is going
on as planned. While the wastes collection practices require wastes to be sorted at generation site, wastes in Nduba are mixed
and good variety of hazardous wastes are dumped. Currently, the site employs 90 workers who separate plastic wastes to be
recycled from other wastes and dump the latter in appropriate pits. Among these workers who are daily dealing with these
wastes, are 23 women (25%). Furthermore, companies involved in wastes collection and their transport, around 500 persons
are involved.
5.3 Nyabugogo wetland and River
Nyabugogo wetland is also another place that is required to be subjected to laboratory test as it has been acting as the sink of
all categories of wastes collected by the runoff either from the city, surrounding areas as well as the former industrial area of
Gikondo.
FIGURE 2: Contaminated site of Gikondo/Industrial Park
11. International Journal of Environmental & Agriculture Research (IJOEAR) ISSN:[2454-1850] [Vol-6, Issue-1, January- 2020]
Page | 27
The latter also makes another potential contaminated site. In fact, the former GIKONDO industrial park was located
upstream of Nyabugogo wetland that gives the name to the river that drain surface water from upstream areas. Many
industries, that were in that area lacked the on-site waste treatment, which sometimes results in illegally sending untreated
discharge into rivers and wetlands. The next map is showing the interconnection between Nyabugogo wetland and
Nyabugogo River with some key pollution hot spots.
5.4 Other Potential contaminated sites
Besides the enumerated dumpsites their other places such where activities that involved articles containing the new POPs
took place for long period that need to be subjected to laboratory test for confusion removing. These include for example
Agakiriro and other places in Kigali where furniture manufacturing took place in the past years.
VI. RECOMMENDATIONS
The limited knowledge and skills on POPs, lack of information access and analytical capacity of POPs are considered as
crucial issues for waste collectors and local communities who are vulnerable to POPs and wastes to fulfill the obligations of
the Stockholm Convention. In order to reduce or eliminate the POPs, the capacity building of vulnerable communities is
needed in Rwanda to save their lives, public health and environment in general. Therefore, the following recommendations
are formulated to an opportunity for waste collectors and local communities to become familiar with POPs information and
environmentally sound management of chemicals and wastes:
It should be better to organize the permanent training of waste collectors and local communities to apply Best
Available Techniques/Best Environmental Practices needed to reduce the production of POPs and waste
management and implement technical environmentally sound management of wastes. Capacity building of waste
collectors and various stakeholders intervening in waste management should be effective and efficient in the
management of chemicals and wastes
Awareness promotion should be organized separately in Hospitals, industries, local communities… and various
stakeholders including CBOs, NGOs and local communities should participate actively and play key role in
chemicals and waste management
Introducing the measures of alternative technologies to improve the incineration systems (eradication lowly
incineration furnaces, low technological condition) and enforce the use of gas tributaries of control systems.
The use of approved incinerator designs that can achieve appropriate combustion conditions (e.g., minimum
temperature of 800o
C, maximum temperature 1500 o
C. currently the medical wastes are burned on the temperature
between 800-900 o
C
The location for the incinerator should be considered to minimize potential risks to public health and the
environment (Minimizing the number of people potentially exposed)
Further studies should be conducted on assessment of POPs management and analytical analysis of POPs potential
in Rwanda and other POPs related researches.
VII. CONCLUSION
In general, in Rwanda, there are the releases of POPs/chemicals and wastes. This affects the environment and public health
negatively according to the frequency and period of exposure. The vulnerable communities (waste collectors and local
communities) should be trained on chemicals and waste management, Best Available Techniques/Best Environmental
Practices and proposed together the way forward to apply with BAT/BEP measures needed to reduce or eliminate the
releases of POPs and technical guidelines of environmentally sound management of wastes including chemicals. The study
proposed the recommendations to be put into action for the efficient results to adapt Best Available Techniques/Best
Environmental Practices (BAT/ BEP) to reduce the emissions of POPs/chemicals and waste management for protecting the
environment and public health.
Therefore, the collaboration and ownership of various stakeholders including local authorities, communities, Civil Based
Organizations, Private Sector and academic institutions should be important for effective and efficient management towards
POPs free environment and waste management for sustainable development. Without environmentally sound management of
wastes; public health can lead to significant environmental degradation and pollution. The contribution of local communities,

especially the waste collectors in cooperatives and companies should be more effective to achieve the management of
chemicals and wastes and pollution control thus save the environment.
