日本北海边电力综合研究所，与地方企业共同时作为肥料来利用的脱硫后的煤灰，进行了开发研究。经燃煤电厂的干式脱硫装置脱硫后的煤灰再掺入鸡粪后可作为肥料有效利用，这不仅是对工业废弃物的再利用，而且对环境保护屯有很大贡献。从1994年开始，该研究所等在地方企业农场对 Japan’s North Sea Electric Power Research Institute, together with local companies as a fertilizer to use the desulfurized coal ash, carried out research and development. Coal ash desulfurized by a desulphurization plant for coal-fired power plants can be effectively used as fertilizer after it is further mixed with chicken manure, which not only reuses industrial waste but also contributes a lot to environmental protection. Since 1994, the institute has been waiting for local business farms
