Dengzhou AMMS GHG Mitigation Project

The project activity is to treat the manure and wastewater from swine farms in Dengzhou city, Nanyang City, Henan Province. It consists of seven subsidiary swine farms. Each subsidiary swine farm installs one animal waste management system (AWMS), and the manure is treated on site. The purpose of the project activity is to treat the manure and wastewater to avoid methane emissions generated in the baseline uncovered anaerobic lagoons. All the manure and wastewater are collected and then be separated first. The solid will be treated in aerobic composting system and the organic fertilizers will be produced, which partly will be supplied to the farmers living around free and others will be sold out to the market. The liquid will be treated through anaerobic digestion and the biogas generated during the treatment process will be captured and then sent to the boiler for heat generation. Total 5,595.63*104m3 biogas are expected to be generated annually. Surplus biogas will be destroyed through the flaring system. The sludge produced from anaerobic digestion will be treated together with the separated solid through aerobic composting, the effluent will be supplied to the farmers living around free for agriculture irrigation. Benefited from the “waste-biogas-fertilizer” pattern, harmlessness and ecological utilization of the swine manure can be realized. One boiler will be installed in each subsidiary swine farm and total 1,678,685GJ of heat are expected to be generated. And all the heat generated are used by the operation of AWMSs and swine farms, which was provided by the coal-fired boiler without the proposed project. Since all the heat is used by the operation of AWMSs and swine farms, therefore the baseline emissions associated with heat generation will not be claimed, which is conservative.
