1.2 STATEMENT OF THE RESEARCH PROBLEM
In the pursuit
of sustainable waste management, the prevention of waste generation is
the first priority, followed by waste recovery and safe disposal of
waste on the hierarchy of principles for waste management (Figure 1.1).
These principles need to be put in practice through joint waste
prevention and management measures if growing environmental degradation
is to be avoided. For example, the use of valuable land for waste
disposal, the release of harmful substances from landfills and waste
transports into air, soil and water, and the use of resources that are
transformed into disposed waste instead of being reused or recycled will
all have negative impacts on the environment, and will have a
long-lasting direct and indirect influences on the quality of life
(European Urban Waste Management Cluster (EUWMC), 2005).
It is known
that there have been some local methods by which solid wastes were been
reused or recycled. The knowledge of waste reuse and recycling might not
be totally new in the Nigerian context. Rather, it is the current
sophistication involved that is rather new. Waste facilities in
developing countries are minimal, but substantial quantities are
diverted for recycling (Tajuddeen, 2003). So there was this reuse
culture that has been planted in to Nigerians subconsciously. Every item
used were structured for reuse. Even today, the sachets of ―pure water‖
are used by horticulturists for flower nursery and paper wrappers are
reused. The reuse tradition is what makes old newspapers useful for
wrapping roasted groundnut ( Arachis hypogea Linn) and pop corn (guguru)
or akara, the popular fried beans cake. Apart from the fact that the
reuse culture saves lots of money, it is highly conservative resulting
in waste management (Ajibade, 2005).
In spite of the enormous
benefits associated with sustainable waste management strategies such as
re-use and recycling, only a handful of countries are able to put them
into practice. For instance, most of the economically developed
countries are still unable to recycle much of their waste (Anthony,
2009). Besides, growing land scarcity and stricter environmental
standards now make it difficult for many rich cities to find adequate
and suitable disposal sites for the large volumes of waste being
generated by their urban populations (Pacione, 2005; Charzan, 2002).
The
foregoing review demonstrates that waste to wealth has multiple
socioeconomic and environmental benefits yet it has not been
systematically examined in Zaria. The dearth of such work is an
important research gap needed to be urgently filled.
1.2 RESEARCH QUESTION
The research questions posed are as follows:
1. What are the socio-economic and demographic characteristics of waste management entrepreneurs (WMEs) in the study area?
2. What are the sources and destinations of recyclable Municipal Solid Waste, in Zaria metropolis?
·
What is the quantity of waste materials (metal scraps, plastics and
cans) recovered, reused and transported for recycling?
1. What type of uses are the recyclable materials put into?
2. What are the socioeconomic benefits of waste management to waste management entrepreneurs (WMEs) in the study area?
1.3 STUDY AIM AND OBJECTIVES
The
aim of the study is to evaluate the potential for municipal solid waste
reuse/recycling as waste management strategies in Zaria metropolis to
create wealth and promote a sustainable environment. The specific
objectives are to:
i.examine the socio-economic and demographic
characteristics of waste management entrepreneurs (WMEs) in the study
area ii.identify the sources and destinations of recyclable Municipal
Solid Waste, in Zaria metropolis; iii.analyse the quantity of waste
materials (metal scraps, plastics and cans) recovered, reused,
transported for recycling.
1. identify the type of uses recyclable materials are put into in the study area.
2. examine the socioeconomic benefits of waste management to waste management entrepreneurs (WMEs) in the study area.
