ANALYSIS OF WASTE FOR COMBUSTION - THE CASE OF OSAKA-CITY, JAPAN

An analysis of the composition of waste for combustion is presented. T he experimental protocol adopted for this study is the one used in Osa ka city. Results over several years are given. A new format by which t o describe physical, proximate and elemental composition as well as he at properties, is presented. Empirical values of the proximate composi tion of combustible components are given. These values are for composi tion estimates of some wastes. It is not clear exactly where and how m uch ash is generated in a municipal waste incinerator. Waste compositi on data enable the ash mass balance of an actual incinerator to be est imated. The methodology of elemental analysis is discussed. Chlorine a nd sulfur were determined by the tube combustion and bomb combustion m ethods. Comparisons suggest that the tube combustion method is prefera ble for pollution assessment. (C) 1997 Elsevier Science B.V.
