CHAPTER ONE 1.0 Introduction
This chapter introduces the research study. It gives the background to the study, statement to the problem, research questions, scope and the significance of the study, definition of terms and organization of the study.
1.1 Background to the study
Solid waste management practices are essential component of environmental infrastructure in human settlements. These practices encompass all activities undertaken from the point of waste generation up to the final disposal. In most of African urban areas, solid waste management is ultimately a responsibility of Municipal Councils while most cases of rural areas the wastes are handled and disposed at the household level (Frank, 2006). Solid Waste Management (SWM) is major environmental issues particularly in municipalities of many developing countries that has been suffering from environmental problems. Alamgir, Donald, Roehl and Ahsan (2005) assert that urban population growth and economic development should be considered key issues for Municipal Solid Waste (MSW) generation. Increasing unplanned urbanization along with user’s mindset of ‘out of sight out of mind’ of wastes is one of the factors that make the production of solid waste to increase and though intensifying environmental pressures including unorganized waste disposal in many municipalities. In many cases, the, SWM is found to be a major concern for the municipalities and towns of many countries and Nigeria is not an exception (ADB, 2012).
Waste segregation is an act of dividing waste into dry and wet. Dry waste includes hard materials such as wood and related products, metals and glass and so on. Wet waste typically refers to liquid or organic waste usually generated by eating establishments and are heavy in weight due to dampness.
Waste generation is increasing, while a sizeable portion of it is disposed on improperly located and operated dumpsites, resulting in dire impacts on environment and health. In addition, Mtey (2005) and Vincent (2000) report that between one-third and one-half of the solid waste generated within most cities in low and middle-income countries is not collected. They usually end up as illegal dumps on streets, open spaces and wetland; and the consequences to have never been favorable to flora and fauna. The Ministry of Infrastructure further reports that solid waste management needs to be reinforced through national policy and regulatory framework to addresses environmental issues.
Accordingly, Abuja town’s waste contains still 70 percent of organic, biodegradable waste and in rural areas the portion of waste reach more than 95 percent. Waste sorting, composting and recycling activities have been at the very beginning and until 2015 and yet Nigeria has started to invest in environmentally safe landfills. The operating dumpsite receives about 400 tons per day of solid, not sorted waste or 140,000 tons per year (MININFRA, 2013). Deep seated fires, methane explosions, landslides and leakages threatening rivers and groundwater are some of the common problems of such basic dumpsites as environmental threats (Hogan, 2004). The current thinking is that poor waste management reflects largely the failure of the existing institutions to adequately address the waste problems (Yekeen, 2010). Any initiative to build capacity by urban institutions has to become attractive and conducive to environmental safeguard. Capacity needs to be weighed and understood at all level, formal and informal, to aid capacity building and then capacity assessment that is concerned with identifying existing capacity and what additional capacity is required to get things done (NUDB, 2008; Yekeen, 2010).
1.2 Statement of the problem
The management of solid waste stands as the most visible environment problem facing the country Nigeria and is attaining a worrisome dimension with urbanization increment rate. Despite the rapid growth of its population, areas such as Abuja have never had any clear Master plan to re-organize the planning and settlement since colonial era. This has put pressure on the infrastructure which has resulted in many complex problems regarding settlement notably waste management, where the solid waste problem is visible in most parts of the area’s urban centers; on the roads, within the neighborhoods and around residential buildings and in different places of the urban areas. Failure to address waste management related issues is expected to lead to numerous social and environmental contaminations.
