Thermochemical Conversion of Municipal Solid Waste — An Energy Potential and Thermal Degradation Behavior Study

A. Hlaba, A. Rabiu, and O. A. Osibote
Abstract—Solid waste management has become an ever growing problem world-wide due to rapid urbanization and population growth. South Africa was found to have generated 59 million tons of general waste in 2011 with the Western Cape generating 675kg/capita/annum. The convention of management has been that of landfilling, however this method is fast becoming insignificant due to the lack of space and detrimental nature to environment. In light of the energy security issue South Africa is facing, and the global drive of finding alternate sources of fuel with the depletion of fossil fuel, attention has turned to MSW as a sustainable source of energy while remediating its effect on the environment. Thermochemical conversions of Municipal Solid Waste (MSW), thus presents an attractive means of harnessing the potential value in this waste stream thus thermochemical conversion pose an attractive means of converting this waste stream into valuable fuel products. Study was conducted making use of RDF pellets produced from the MSW. Pellet density was varied by varying the starch binder to MSW ratio, thus the effect of this on energy content and thermal degradation behavior was studied. The energy content of MSW in Cape Town was investigated using a bomb calorimeter and the thermal degradation behavior was studied using Thermogravimetric Analysis (TGA). The MSW calorific value was found to average at 19MJ/kg and 3 distinguishable major mass loss regions were found between temperatures 55 – 265oC, 270 - 410oC and 410 - 502oC. The total mass reduction was found to be 76%.

Index Terms—Calorific value (CV), proximate analysis, refuse derived fuel (RDF), thermo-gravimetric analysis (TGA), derivative thermogravimetry (DTG).
