Zero Waste and Conversion Efficiencies of Various Technologies for Disposal of Municipal Solid Waste

Zero waste is a philosophy and a design principle of dealing with our waste stream for the 21st century. After reviewing the available information, the goal of zero waste from landfill is considered to be unachievable by using known and proven methods and approaches. The comparison of various technologies shows that the conversion efficiencies depend upon the type of system chosen for processing residual waste, and the best overall diversion rate of waste management system that can be achieved is about 71%. The maximum achievable overall diversion rate can be increased to approximate 92% if current environmental regulations to permit the routine use of the bottom ash or char for advanced thermal technologies.     

各类生物质废物在高固体混合厌氧消化系统中的优势营养组分互补机制及其对过程代谢产物的影响研究

有关生物质垃圾中、高温高固体厌氧消化技术，我国长期以来并未受到重视，研究大多均限于实验室研究和一般工艺条件的探讨。国家是在2006年以后，面对日愈突出的资源环境与发展的矛盾，才逐渐将开发生物质再生能源与开发其他可替代／再生能源提到国家战略高度予以重视。
