ABSTRACT Municipal solid waste management has emerged as one of the greatest challenges facing environmental protection agencies in developing countries. This study presents the current solid waste management practices and problems in Nigeria. Solid waste management is characterized by inefficient collection methods, insufficient coverage of the collection system and improper disposal. The waste density ranged from 280 to 370 kg/m3 and the waste generation rates ranged from 0.44 to 0.66 kg/capita/day. The common constraints faced environmental agencies include lack of institutional arrangement, insufficient financial resources, absence of bylaws and standards, inflexible work schedules, insufficient information on quantity and composition of waste, and inappropriate technology. The study suggested study of institutional, political, social, financial, economic and technical aspects of municipal solid waste management in order to achieve sustainable and effective solid waste management in Nigeria.

    ABSTRACT: Managing municipal solid wastes (MSW) is progressively becoming a major challenge in many cities of developing nations because of rapid urbanization and rise in population. This can be described by ineffective collection methods, inadequate coverage of the collection, processing system and inappropriate disposal. This paper presents the current state of solid waste management in a semi-urban city, its associated challenges and prospects that are within. A field work that involves the characterization and types of the waste generated, and frequency of collection was carried out within the study area. Four locations where the major waste bins are located within the city were considered. A representative sample of 280 kg was used for the waste characterization, and the results show that about 64% of the wastes are recyclable with lots of organic waste that can be used as compost. The only dump site in the city was visited in order to obtain useful information concerning the present state of solid waste management. The study revealed that there is presently no investment made to the existing development plan to introduce a modern waste management system. The study suggests new approach that could be used by institutions and government agencies for MSW management to realize a sustainable and efficient sanitation, and possible resources generation potentials that could be harnessed from the waste stream.

    ABSTRACT: This paper presents the study of municipal solid waste (MSW) as a potential source of renewable energy in Arusha city. The city of Arusha annual average MSW generated was estimated at 43,772 tonnes. Characterization revealed the main components of MSW to compose of biomass materials such as food, paper and wood waste. Based on the characteristics of the MSW, evaluation was conducted to determine energy potential that would be recovered. Results from proximate analysis of MSW samples showed average calorific value of about 12MJ/kg which indicate annual energy potential of 128.9 GWh. Results indicate there is a substantial energy potential to recover from MSW the largest share being renewable energy. The composition of waste from developing and developed countries was further compared with that of Arusha city. Results indicated that in developing countries characteristics of MSW is mainly composed of food waste as was the case of Arusha city.
