The comprehensive treatment pattern of municipal solid waste (MSW) based on category classification of Beijing

Detailed investigations on the physical composition and properties of MSW in the experimental districts revealed that high moisture and high percentage of kitchen waste are the main limiting factors in the recovery of recyclables. A new category classified system, according to which MSW was classified as kitchen waste, other waste and ash waste, was proposed of South Beijing. In addition, a corresponding MSW treatment pattern that involves all compost for kitchen waste, incineration for other waste and landfill, for ash waste and residues of composting and incineration were constituted to promote efficiency of waste disposal. The recycling rate, benefit cost ratios and the production rate of compost were improved about 65.0%, 31.6% and 82.9%, respectively. But the landfill capacity was reduced by 81.6% for the category classified MSW as compared with mixed collected pattern.
