This project work “appraised the current solid waste
disposal"option in Wudil Kano State. The town was divided into four zones
namely zone A, B, C, and D. The per Capita solid waste generation for each zone
was found to be 0.24kg/person/day, 0.16kg/person/day, and 0.13kg/person/day for
zone A, B, C and D respectively. And the average value for the entire town was
0.18kg/person/day. The major disposal method adopted by the town was open
burning which brings many societal problems including air pollution.Using the
current population figure of the town, the estimated solid waste generation was
48,839kg/day. It was suggested that the best disposal method to be adopted in
the respective zones of the town specifically zone A and zone B is composting
but for zone C and zone D is incineration.

CHAPTER ONE
INTRODUCTION
1.1 Background of the study
Right from the existence of
humanity, several resources are in continuous usage in one way or the other to
support life, and after usage they are of no value and therefore may require
disposal.The disposal of the unwanted or used materials produce which is
considered as waste, which is either solid or liquid wastes. Solid waste
according to Mill, (1988) is any useless, unwanted, or discarded materials that
is not liquid or gas. A mixture of substances including fine dust, cinder,
metals, glass, paper, textiles, vegetable material and plastics etc. are called
solid waste (Simon, 1981).
Solid waste in
particularly are all the waste arising from human and animal daily activities
that are usually solid and are discarded as useless or unwanted (TADESSE, 2004). If it is not properly
discarded or manage, these waste generated on daily basis bring hazard to the
society living in the environment. Improper disposal bring about an unpleasant
environmental appearance (sight pollution).by causing blockage of hydraulic
structure like culvert, and drainages bad atmospheric aeration, boom in a
diseases outbreak and environmental unfriendly problems.
Waste management is a
serious global issue which is considered more challenging in developing
counties where a high percentage of waste is currently dispose by open dumping.
The environment plays a significant role in the ability of nature to sustain
life within it is capacity. Solid waste is seriously threatens the
sustainability of the environment with implications on human health.
Waste left on the street
create unpleasant odour and breeding ground for bacteria, virous and insects
such as cockroaches, mosquitos and others causing diseases and illness.
Hazardous materials from randomly and incorrectly dumped waste can seep into
the ground and pollute water resources including groundwater etc. and
therefore, the pollutant each the human body through drinking water,
vegetables, and animals product. And also burning solid waste pollute the air
causing serious health risk, including respiratory infections like cancer,
asthma and other related illness.
Millions tons of
municipal solid waste are generated annually in Nigeria and the waste
generation ate range from 0.69kg/cap/d in urban areas and 0.49kg/cap/d in rural
areas. In Nigeria, wastes are usually dumped on roadside, available open pits,
flowing gully water and drainage channel. These indiscriminate disposal
practices are prominent in most urban cities where most of the wastes are
generated. The generated ate directly proportional to the population,
socioeconomic status and level of urbanization, hence the quantity of waste
generated varies from one state to another and also increase per year. The
composition of waste generated per state is a function of socioeconomic, industrialization,
and commercialization status in the area. (BITCHI et al 2013).
In Nigeria the processes
involve in waste management are collection, storage, transportation, and
disposal at appropriate dumpsite. In the case study WUDIL town all waste are
collected together without sorting o recycling and dispose of to the closet
dumpsite.
The analysis of the key
problems affecting the efficient management of municipal waste is critical for
evolving a workable solution in an emerging economy Nigeria. At the core of
solid waste management issue, are the absence of adequate polices, enabling
legislation and an environmentally stimulation and public enlightened. Although
there are several legislation regulating waste management practice in Nigeria
such as law settling up the use of task
force to ensue collection of solid at a specified time and location and
particularly the schedule Saturday as the general inspection day for general
cleaning of the environment. These laws are consider to be strict being
offshoot of the military regimes, and as such not effective. The aim of this
project wok is to carry out a thorough appraisal of solid waste management and
disposal practice in WUDIL town KANO state NIGERIA and make recommendation that
can help in it is improvement where necessary.
1.1 AIMS AND OBJECTIVES
1.1.1 AIM
1. The aim of the project is to study the existing solid waste management
practices in wudil and collects information which will assist the residents of
the study area on how to dispose their solid waste in a selected area provided
by the government or community base organization (CBO),more appropriately.
2.The project also aims to clear the
environment, thus improve the quality of sanitation and hygiene.
3. To determine and locate where the
problems are within the solid waste management
1.1.2 OBJECTIVES
1. To determine
the existing solid waste collection and disposal practice
2. To determine
the per Capita and total waste generation of the study area.
3.To conserve the
environment, improve community health and cleaniness and influence residents
participation in proper waste disposal.
1.2 STATEMENT OF THE PROBLEM
The
generation of these waste is inevitable but the method of disposal is a big
challenge and is causing a problem to the WUDIL town with the improper method
of waste disposal system. The health of the inhabitant are at risk, the environment become slightly unpleasant,
hydraulic structures such as culverts and drainage are blocked. Thus, increasing
the rates of flooding. But solution to these problems, is the reason for
carrying out this project wok so as to propose an effective waste management
system and stop the menace of
indiscriminate disposal.
1.4. Limitation of the study
The study is limited only
to some areas within WUDIL with likes of the stated problem limited to the
above mention objectives.
1.5 Scope of the study
This research appraises the common method of
disposal and effects of improper solid waste disposal in WUDIL
1.6 Study area
Wudil town is
geographically situated on latitude 11.570317N, 11.869425N and longitude
8.779696E, 8.936728E of the Greenwich meridian, as shown in Figure 1. The town
has an estimated landmass of 458km2. The climate of the area is basically wet
and dry season classified by Koppens as the Aw. The mean annual rainfall is
about 850mm. The mean annual temperature about 26˚C, but mean monthly
temperature value ranges between 21˚ in December/January and 31˚ around
April/May. The geology of WUDIL falls within the Northern Nigeria basement
complex rocks. The major landforms that can be identified within the area are
the river channel, a low terrace, the high terrace and the uplands plains
(Olofin,1987). The three soil types found within the region are Lithosols,
Hydromorphic and Regosols soils (Muhammad Isma’il, Saidu Abubakar). The natural
vegetation of the area is characterized by moderately tall grasses and
scattered trees that are deciduous in nature. WUDIL town existed since 1804 and
the early settlers were fishermen who first settled near the river valley for
fishing purposes. The earliest inhabitants of the town are Hausa by tribe.
Three major factors are responsible for the early attraction of the people into WUDIL
zone.
