Abstract:
The objectives of this research were to identify the contribution from solid waste major sources in MBK shopping center by using composition mass balance model and to study the physical composition of solid waste from the sources and the solid waste central storage room. Six major sources were considered in this model including restaurant, office, shop, bin, department store and supermarket.The result showed that the major sources of solid waste at MBK shopping center were following as: restaurant (72.8%), department store (16.9%) and bin (5.9%), respectively. The model computed R2 value of 0.95. This means that the model accuration is 95 percentage. However in the case of office, shop and supermarket, the model could not accurately predict the source contribution because of the similarity of the physical composition of solid waste from each sources. Source profiles could be used in source contribution prediction at other shopping center. The physical composition re-analysis of solid waste in the solid waste central storage room must be proceeded.Besides, source profiles could be used as the data base for management planning selection.The physical composition analysis by wet weight for MBK shopping center showed that the main compositions are garbage, paper and plastic.
