Measurement of the Potential Heat and Ash Content of the Residue from Mechanical Biological Treatment in Thailand

抄録

Mechanical biological treatment (MBT) is known as one of the most attractive method of waste treatment, which is to reduce the waste volume and avoid the landfill. The purpose of this study is to figure out the low heating value (LHV) and ash content of the MBT residue. The effect of the additional separation against the MBT residue on the reduction of landfill waste was also discussed. The MBT residue was sieved experimentally. The potential heat as LHV and ash content of the separated fractions of the residue were determined. LHV of all separated fraction were lower than the criteria (>17 MJ/kg) of Refuse derived fuel (RDF) for using cement industries. Ash content of all separated fractions were higher than the criteria (< 20%) of RDF. The results indicated that the sieved fractions could not be used as RDF directly. Fractions of 40mm, 20mm, 10mm on the sieve and 2mm passing the sieve could be used as fuel material by combining with RDF product. It was suggested that the additional separation against the MBT residue using 10mm mesh sieve was the most contribute to reduction of the landfill waste and increase of RDF production in this experimental condition.
