An approach to comparison of municipal solid waste management at country level
MSW management is an integrated process from collection at the source to final disposal. Currently, source separation is often preferred in waste collection, and the landfill is a main treatment technology in most countries. In this paper, a curve, named as separation-landfill curve (SLC), is proposed for comparisons of MSW management among countries. The SLC describes the change in the ratio of landfill to other treatment technologies including combustion and composting with the number of waste separation at the source. The MSW management of ten countries in the world is selected for comparisons by means of SLC. In theory, SLCs fall into three groups, which are linearly decreasing, concave downward and concave upward, according to the physical composition of specific MSW. Each group is representative for one of MSW management modes. However, actual SLC usually deviates from the theoretical one due to inefficient implementation of MSW Programme. The gap between theoretical SLC and actual one could be used to assess MSW management. Experiences from countries in the same group of MSW management model are more valuable for each other.
