To promote the reuse of digestate, this project drafted strategies for promoting digestate use as farmland fertilizer by analyzing the successful foreign cases, proceeded the meeting with agriculture and animal husbandry, updated permission cases status, and also studied the feasibility for the reuse of digestate as raw material for farmland fertilizer. As for promoting anaerobic digestion, this project had drafted the “Assessment of the treatment technology and promotion strategy for the centralized anaerobic”, “Assessment of the treatment technology and promotion strategy for the supply of margin for anaerobic digestion facility with piggery waste”, “Assessment of the treatment technology and promotion strategy for the centralized power generation technology from biogas”, “Feasibility study of anaerobic co-digestion of piggery waste and organic waste”. In the supplementary work, this project had completed the assessment of pollutant reduction from digestate use as farmland fertilizer discharging into river, conducted review meetings regarding local government promoting status, visited abroad, completed translation of foreign management guidance documents, drafted policy memorandum and irrigation guidelines. The main accomplishment for this project included completing and promoting 5 Strategies (Strategy of promoting digestate use as farmland fertilizer, Strategy of promoting matching-service for agriculture and husbandry, Strategy of promoting digestate use as centralized anaerobic treatment, Strategy of the supply of margin for anaerobic digestion facility with piggery waste, Strategy of centralized power generation technology from biogas), 12 matching and information briefing sessions, online agriculture and husbandry matching platform, 2 review meetings regarding local government promoting status, 8 translated documents on foreign management guidelines and technical exchange issues, 2 policy memorandum on digestate use as farmland fertilizer in both Chinese and English version(separated into expert edition and general public edition) and 1 irrigation guidance manual.
