Evaluation of biogas production and slurry from organic solid wastes for agricultural productivity and rural development

This research is to evaluate biogas production and slurry using organic solid wastes for agricultural and rural development. Solid wastes management have been a major challenge for Metropolitan, Municipal and District Assemblies (MMDAs) as the organizations responsible for managing wastes in their communities. The major challenges identified are the lack of separation of wastes, low technological know-how, inadequate landfills and lack of basic infrastructure for managing the wastes. The research involved a visit to various regional and district capitals to observe waste management challenges; a thorough review of literature on solid wastes and biogas technology. It was observed that about forty percent of solid wastes are not collected and heaps of wastes have become common in some of the cities. The research also revealed that the solid wastes are mostly collected and disposed without treatment and such wastes contain over fifty percent organic matter. It was also discovered that so much money is spent on wastes management alone which has a toll on the MMDAs especially AMA. The research indicated the process involved in the conversion of organic solid wastes component into energy and slurry for agricultural productivity and rural development. The research outlines the energy content of organic solid waste, composition and application of the biogas and the digested slurry. It further stated the measures to ensure sustainable biogas project and concluded with suggested recommendations.
