A novel approach for chemical looping gasification of municipal solid waste

传统的城市固体废物处理方法，如填埋和焚烧，因其对环境的不利影响而面临社区的强烈反对。建议的气化工艺具有能耗低、制造成本低、操作简单等特点，将为城市生活垃圾处理提供一种有效的替代方案。如果在全国范围内部署，每年将减少500万吨垃圾。相应减少的温室气体将是1500万吨二氧化碳当量或国家净排放量的2.7%。还可以生产约9太拉瓦时的电力(占全国需求量的3%)，每年产生7亿美元。

Conventional methods of municipal solid waste disposal, such as landfill and incineration, face strong community opposition because of their adverse environmental impacts. The proposed gasification process with its features, such as low energy demand, inexpensive manufacture, and simplicity, will offer an effective and alternative solution to the problem of municipal solid waste disposal. If deployed across the country, the volume reduction of waste will be 5 million tonnes per year. The corresponding reduction in greenhouse gases will be 15 Mega tonnes of carbon dioxide equivalent or 2.7 per cent of the net national emissions. About 9 Terra Watt hours of electricity (3 per cent of the national demand) can also be produced, generating $700 million per annum.
