%X Municipal solid waste management of urban communities has difficulties of insufficient source separation and food waste's high moisture content, an integrating technology of manual separation, simple compression of food waste, reclaim of food waste and composting leachate was studied. Manual separating rate was 36.8 kg/h, and would increase when the worker became sophisticated. Community separated food waste had high organic matter content of 44.493%, nutrients N, P, K contents of 2.586%, 0.649% and 1.274%, C/N ratio of 17.427, but 0.07-0.82 times lower heavy metals contents compared to centralized separation of mixed municipal solid waste. Moisture content of food waste was still 78.7%, high enough to have negative impacts of composting processes. Composting leachate processing with biological stabilization and dilution showed a fertilizer efficiency, and dry weight of impatiens irrigated with composting leachate was 1.46-2.49 times of tap water irrigation. Integrating technology based on community's manual separation could decrease 52.6% municipal solid waste.
