Characterization of Fresh and Aged Municipal Solid Wastes (MSW) in Shanghai and Recycling Combustibles from Aged MSW to Improve Fresh MSW Incineration
Aged municipal solid wastes (MSW) including those excavated from landfill and dumpsite have been characterized and compared their components, moisture content and lower heat value (LHV) with fresh MSW in order to recycle and dispose them properly. The results showed that combustibles in aged MSW were easily to be separated from other components and their LHV is higher than 11000kJ/kg as just separated; while the fresh MSW are of high moisture contents and their LHV is below 6500kJ/kg. The main contributor to LHV is plastics for both fresh and old MSW and when plastics were separated from fresh MSW, their LHV decreases significantly. The separate combustibles from aged MSW were made into RDF and added to fresh MSW by 2%~5%wt to check their influence on air supply and LHV. Experimental data proved that combustibles from aged MSW are a promising auxiliary fuel to improve fresh MSW incineration
