Municipal solid waste management (MSWM) is a global challenge and the situation is worse in urban areas of developing countries due to ineffective disposal systems. In many industrialised countries, waste minimisation and recycling/reuse policies have been introduced to reduce the amount of waste generated, and increasingly, alternative waste management practices to waste disposal on land have been implemented to reduce the environmental impacts of MSWM. Nevertheless, research and MSWM in most developing countries have largely concentrated on waste collection. This doctoral study investigates how planning and decision-making for MSW disposal in developing countries with similar circumstances and MSW problems to Ghana can be improved, using the Wa Municipality as a case study. It established the baseline scenario of MSW disposal and examined MSW disposal management and operational performances. The methodology and research design for the study was a descriptive and interpretive case study that was analysed through both qualitative and quantitative research methods. The key research findings indicate that the current state of MSW disposal management performance in Ghana does not present an enabling environment for effective MSW disposal. Also, the present MSW disposal practices in the case study area and Ghana in general consist of some waste collection, transportation and open dumping, where the entire amount of waste is open dumped without pre-treatment. Evaluation of MSW disposal operational performance through modelling and scenario analysis showed that open dumping/landfilling of waste creates copious health effects (0.0001519 lbs/year on average), whereas, MSW disposal in an integrated solid waste management (ISWM) system optimises the minimisation of health effects (-0.0005812 lbs/year on average). The study developed and validated a framework for the improvement of planning and decision-making for MSW disposal, which can easily be applied in the context of developing countries. Also, the developed framework provides a theoretical standpoint for the concept of MSW disposal in ISWM. Appropriate MSW disposal treatment technologies based on the developed framework could be applied to ameliorate the impacts of MSW disposal in Ghana and other developing countries.
