Abstract

Modified Dulong’s model (MDM) was used to estimate the energy contents of municipal solid waste 
(MSW) from Aba dumpsites. American Society for Testing and Materials standard methods (ASTM) were 
used to determine percentage composition and ultimate analyses, thermal degradation and energy content 
the MSW. The results of % composition of the MSW showed that plastic (2.50 %) was the lowest while 
food waste (65.00 %) was the highest. The ultimate analysis results are carbon (44.50-62.50 %), hydrogen 
(4.30-8.50), oxygen (33.50-43.50 %), nitrogen (0.00-5.50 %), S (0.00-0.68 %) and Ash (2.5-8.00 %). The 
energy content of the MSW which was calculated using MDM found to be 20.53 mJ/kg. The result revealed 
that I kg of MSW from Aba dumpsites can produce about 21mJ/kg of energy. Therefore, conversion of 
MSW to energy can serve as profitable means of managing environmental pollution in developing nation 
and elsewhere in the world.
