a case study of municipal solid waste management in the ... - lumes

Page 32Therefore, through the simply social psychologyapproaches is:1. composting & landfill2. sanitary landfill3. incinerating & landfillanalyses, the sequence of these three7.6 Comprehensive AnalysesFirst of all, municipal solid waste of Jingshan has two obvious features as describedearlier, Olle is high organic composition, another is low of heat value. Approximate65% of municipal solid waste is organic waste (see table 1), and the heat value ofmunicipal solid waste rang e from 800-1100kCal/kg which is six times lower thanVancouver' s municipal solid waste as mentioned before. In this case, composting &landfill approach will be much more appreciated than incinerating & landfill approachfor Jingshan.Furthermore, crude dumping is firstly eliminated through the method of systemanalysis. And through economic analyses, the approach of combination ofincinerating, composting & landfill is also eliminated afterwards. The rest threeapproaches will be ranked in accordance to the orders in different analysisperspectives. The selective fUles are the worst Olle among these three approaches isconsidered 1 credit, the best Olle is considered 3 credits, the middle Olle is considered2 credits. If the best Olle and middle Olle could not be determined, these two are bothconsidered 2 credits, and the worst Olle is considered 1 credit. If the worst Olle andmiddle Ollecould not be determined, therefore, these two are both considered 1 credit,the rest Olle is considered 3 credits. Table 3 shows the credits of different analyses.The comprehensive analyses is the results of total credits of these approaches throughthe different analyses methods:
