The operations of carbonization facilities for municipal solid waste treatment in Japan were examined. Input waste, system processes, material flows, quality of char and its utilization, fuel and chemical consumption, control of facility emissions, and trouble areas in facility operation were investigated and analyzed. Although carbonization is a technically available thermochemical conversion method for municipal solid waste treatment, problems of energy efficiency and char utilization must be solved for carbonization to be competitive. Possible solutions include (1) optimizing the composition of input waste, treatment scale, organization of unit processes, operational methods, and quality and yield of char on the basis of analysis and feedback of long-term operating data of present operating facilities and (2) securing stable char demands by linking with local industries such as thermal electric power companies, iron manufacturing plants, and cement production plants.
对日本城市固体废物处理碳化设施的运行情况进行了考察。调查和分析了输入废物、系统工艺、物质流、炭的质量及其利用、燃料和化学品消耗、设施排放控制以及设施运行中的问题领域。虽然碳化是一种技术上可行的城市固体废物处理热化学转化方法，但碳化要具有竞争力，必须解决能源效率和炭利用的问题。可能的解决方案包括：（1）根据现有运行设施的长期运行数据的分析和反馈，优化输入废物的组成、处理规模、单元工艺的组织、操作方法以及炭的质量和产率；（2）通过与热电厂、炼铁厂和水泥厂等当地工业建立联系，确保炭的稳定需求。
