Refuse Derived Fuel Pellets as a Renewable Energy Source

. The South African Government, through the National Development Plan of South Africa, aims to provide access to the grid and off-grid electrical power to a minimum of 95 % of the population by 2030, of which 20 GW of the required 29 GW required for this needs to come from alternative and renewable energy sources. The study conducted using MSW from the City of Cape Town Municipality in South Africa shows that the MSW has a calorific value of approximately 19 MJ/kg which is significantly high, meaning that the waste can be directly used as fuel in many applications but more importantly that of electricity generation. The calorific value for the pelletised waste was found to be higher at an average of 23.9 MJ/kg which can be compared with South African coal being 25.1 MJ/kg. Using TGA, 3 distinguishable major mass loss regions were found between temperatures 55 - 265℃, 270 - 410℃ and 410 - 502℃. The total sample reduction was found to be more than 90% on average which is a reduction of the waste.Cape Peninsula University of Technolog
