COMPREHENSIVE UTILIZATION OF HUMAN AND ANIMAL WASTES

The paper discusses how to treat human and animal wastes with anaerobic digestion to obtain environmental and sanitary benefits as well as various approaches to utilize biogas and biogas fluid and biogas fermentation residues. In rural area biogas technology treating human and animal wastes is closely connected with the development of sustainable agriculture, which can rationally balance energy exploration, environmental protection, social progress and economic results. Moreover, it is possible to establish various eco-agricultural patterns linked with biogas suited to local conditions. Efficient organic liquefied fertilizer is developed from human wastes while anaerobic digestion is adopted to make public-hazard-free excrements from public toilets in cities.
