Evaluation of the heating (Calorific) value of municipal wet solid waste from Kabagarame Dumping site in Bushenyi District, Uganda.
Modern management of waste around the world has moved from waste disposal toenergy recovery through WtE. Technologies that can be utilized to recover energyfrom MSW via thermal conversion processes such as incineration, gasification,pyrolysis, biochemical conversion processes and chemical conversion. The aim of thisresearch was to evaluate the heating (calorific) value of municipal wet solid wastefrom Kabagarame dumping site in Bushenyi District, Uganda. Wet solid waste sampleswere analyzed, the heating value of the wastes were evaluated. The results showedthat other organics had the highest calorific value of 26.22 MJ/kg, followed by paper16.60 MJ/kg, followed by food waste 16.51MJ/kg and then wood 16.14 MJ/kg on drymatter basis. The results on the heating value on wet basis showed that other organicshad the highest calorific value of 12.82 MJ/kg, followed by paper 14.04 MJ/kg,followed by food waste 13.66 MJ/kg and then wood 9.89 MJ/kg. The heating value ofplastics was not obtained since they are recovered from the dumping site andrecycled. This energy can be harnessed by different production facilities particularlyTea factories in the region through incineration process so as to generate heatnecessary for their production processes. In conclusion, results from this researchalso suggest that understanding the composition of municipal solid waste is essentialfor creating the best disposal strategy, so that recovering resources trapped in thewastes can be optimized. It is therefore necessary that energy derived from municipalsolid wastes can be taken into account in the national energy budget.
