This document discusses sustainable waste management strategies in Nigeria. It outlines the types of waste generated, including municipal solid waste, hospital waste, hazardous waste, and e-waste. It then discusses approaches to waste treatment, including prevention and minimization, reuse, recycling, composting, and landfilling. The document also provides case studies of waste management initiatives in Lagos State by the public sector waste agency LAWMA and private sector companies that collect, sort, and process recyclable materials.

3. INTRODUCTION:
In Nigeria, generation of municipal solid waste (MSW),
industrial hazardous waste and biomedical waste have
been increasing due to population growth, life style
changes and economic development. On the other hand,
waste management responses have not kept pace with the
increasing quantities of waste resulting in:
(a) a high proportion of uncollected waste, and
(b) poor standards of transportation, storage, treatment
and disposal.
The insanitary methods adopted for disposal of solid
wastes is a serious health concern with significant
environmental, social and health costs associated with it.
Open dumping of garbage facilitates the breeding of
disease vectors such as flies, mosquitoes, cockroaches,
rats, and other pests. The poorly maintained landfill sites
further, are prone to groundwater contamination because of
leachate production.

4. KEY ISSUES INVOLVED
 Growth in population and increasing garbage
generation
 Waste collection system
 Scientific processing of the waste material
depending on their nature
 Developing infrastructure for solid waste
disposal and processing
 Developing information collection and
processing system
WASTENOMICS

5. MUNICIPAL SOLID WASTE
 Such waste comprises
household waste, construction
and demolition debris,
sanitation residue and waste
from the street.
 The consumer market has
grown rapidly leading to
products being packed in
cans, aluminium foils, plastics,
and other such non-
biodegradable components
which cause immeasurable
harm to the environment.

7. COMPOSITION OF MUNICIPAL WASTE

8. HOSPITAL WASTE
Hospital waste is
generated during the
diagnosis, treatment or
immunization of human
beings or animals and
also in the research
activities in these fields as
well as in the production
and testing of biologicals.
WASTENOMICS

9. HAZARDOUS WASTE
 Hazardous waste could be highly toxic to
humans, animals, and plants; are
corrosive, highly inflammable, or
explosive; and react when exposed to
certain things such as gases.
 Industrial and hospital waste is
considered hazardous.
 In addition, certain types of household
waste are also considered as hazardous.
 The main disposal route for hazardous
waste is landfill, incineration, and
physical or chemical treatment.
WASTENOMICS

10. E-waste
 It consists of end of life
products and comprises of
a range of electrical and
electronic items such as:
 refrigerators,
telecommunication
equipment, freezers,
washing machines, medical
equipment, hairdryers and
televisions.
WASTENOMICS

11. SOLID WASTE TREATMENT/INNOVATION
 Waste Prevention and Minimisation
 Re-use
 Recycle
 Composting
 Land filling

12. SEPARATING THE WASTE INTO DIFFERENT TYPES.
In some country, waste are collect and recycle in this manner:
batteries (white), glass (black), plastic (red), paper (blue) and cans
(yellow). while recycle used equipment and home appliances in
special sections

48. Cost Benefits Assumptions:
1. Loose PET bottles arrive at CoSoHUBs at the rate of N20,000 per ton, the
processing cost is N15,000 per ton and sold at the current local selling rate of
N45,000 per ton. Each CoSoHUB by size has 50 PET Bottle Sorters attached to it,
with each person delivering a minimum target of 3,000 sorted (removing caps and
labels and separating by colour) PET Bottles per day. This brings the cumulative daily
average of 150,000 bottles which equates to 3 tons per day. This gives a monthly
production of 75tons, which are baled to generate net revenue of N750,000 per
month.
2. Aluminum Cans arrive at the CoSoHUBs at the rate of N70,000 per ton, they are
baled with a processing cost of N10,000 per ton and sold at the current local selling
rate of N130,000 per ton. A CoSoHUB processes 30tons of Aluminum Cans in a
month which generates net revenue of N1,500,000 per month.

49. 3. Pure Water Sachets arrive at the CoSoHUBs at the rate of N20,000 per
ton, they are bagged with a processing cost of N5,000 per ton and sold at the
rate of N35,000 per ton. A CoSoHUB sells 35tons of pure water sachets a
month which generates net revenue of N980,000 per month.
4. Brown Corrugated Cartons arrive at the CoSoHUBs at the rate of N5,000
per ton, they are baled with a processing cost of N5,000 per ton and sold at
the current local selling rate of N16,000 per ton. A CoSoHUB processes 50tons
of Brown Corrugated Cartons in a month which generates net revenue of
N300,000 per month.
5. The Operating Plan (Processing Cost) informs that an average of about
N1,836,500 will be spent in operating the CoSoHUB monthly.
7. Each CoSoHUB targets to generate a net revenue of N3,530,000 per
month.

51. Bailing Machine Cost and other Expenditure
Ø Harmony Enterprises, Inc. in United States of America (http://harmony1.com/)
Ø Jiangyin Aupu Machinery Co. Ltd. in China (http://www.aupujx.com/english/index.asp)
Ø Ningbo Sinobaler Machinery Co. Ltd. in China (http://www.sinobaler.com/)
The technology deployed in the manfacturing of these balers make them safe and
economical tohandle. Unlike the American Balers which are plugged directly to
electric mains, most of the Chinese balers have diesel powered generators attached
to them. These models allow for CoSoHUBs to be sited at locations that do not have
stable electrical power connections to the national grid. The price of a standard baler
with generator support range from ₦3,500,000 to ₦4,000,000 depending on the size
of the bales produced and the turnaround cycle-time. The installation and
commissioning cost is about ₦350,000 – ₦400,000 depending on the location. Other
items in the CoSoHUB are floor/platform weighing scales and bale trolleys for moving
bales around.
A standard CoSoHUB facility sitting on about 3 plots of land is structured to house
about thirty (30) bottle sorters, five(5) material handlers, two (2) bale operators and 1
bookkeeper/supervisor
