Abstract 10 kinds composting processes at the Beijing Nan-gong Composting Plant were researched based on fuzzy mathematics and analytical hierarchy process (AHP) analysis. The optimal composting technology of using maturity indexes as the single object required 0~80mm of domestic waste as raw material. And the raw material were mixed and crushed once on the fourth day of the 8 day thermophilic fermentation, followed by a 12 day deuteric maturity period and a 12 day ultimate maturity period(technology 1). The optimal composting technology of using economic index as the single object was same as technology 1 without the crushing process. The optimal composting technology of using maturity indexes and economic indexes as the combined objects was same as technology 1.
