现代工业的发展在促进人类社会物质文明繁荣的同时,导致了大量生物质资源的浪费。随着环境、能源等问题日益突出,废弃生物质资源的再利用研究越来越受到关注。该文在介绍废弃生物质材料丰富来源与传统处理方法的基础上,根据近几年的研究现状及发展趋势,就其循环利用途径进行了详细综述。废弃生物质材料主要来源于农业生产废弃物、农副产品与食品加工废弃物、林业与城市绿化废弃物及生活垃圾。废弃生物质材料的处理已经从传统方法(包括燃烧法、饲料化、肥料化与基质化处理),逐步走向能源化、生态化、材料改性,以及制备基于生物炼制技术的新型生物基功能与智能材料产品。总之,以废弃生物质材料为主要原料,开发新型基质与功能材料是发展趋势。
In past decades, with the development of modern industry, more and more non-renewable fossil resources,such as oil and coal, have been applied to fabricate materials and fuel. It promotes the prosperity of material civilization of human society, but it also causes biomass resources to be discarded and wasted, and results in serious pollution of environment. Therefore, the way to develop the biomass resource, especially the reusing of disused biomass resources has been attracted considerable attentions from governments and scientists over the world. In this paper, based on introducing main resources of waste biomass materials and their traditional processing method, according to the latest research development trends in recent years, the novel pathway for the reutilization of waste biomass materials has been summarized. Waste biomass sources are very extensive and there are varied ways in treating and using these materials.Main sources of waste biomass materials are waste of agricultural production, subsidiary agricultural products, food processing waste, forestry and urban greening waste and life rubbish. Currently, more than 1 billion tons of solid wastes are generated per year in cities of world, and waste generation rates will be more than double over the next 20 years in lower income countries. As the ingredients of biomass wastes are complex, dealing it with improper ways will damage environment and people's health seriously. The traditional methods for processing waste biomass mainly include combustion, feed, fertilizer and matrix. The advantages of these treats are simple operation, high yield and low running charge. However, it can not only cause serious hazards to ecological environment, but also cause the waste of resources.Therefore, more and more technologies for reusing discarded biomass have been developed. A typical ecologic friendly comprehensive technology for reutilization of discarded straw is edible fungi cultivation- feeding pig-biogas generationfertilizing the soil. In some discarded bioma
