茶废弃物综合利用研究进展

摘要

China is a big producer and consumer of tea. A huge amount of tea waste is produced in China every year, resulting in environmental pol ution and enormous natural resources waste. From the perspective of utilization way, this pa-per summarized the research progresses in tea waste as a raw material for ex-tracting active ingredients and preparing absorbent, activated carbon, bio-organic fer-tilizer, animal feed and nutrients for edible fungi cultivation. ln addition, the develop-ment trend of comprehensive utilization of tea waste was prospected. lt is found that the comprehensive utilization of tea waste using a variety of techniques can im-prove the utilization efficiency of tea waste and reduce production costs. Final y, a simple and practical comprehensive utilization program was proposed to provide a reference for practical application.%中国是茶生产与消费大国，每年产生大量茶废弃物，既污染环境又造成生物资源的巨大浪费。笔者从利用途径的角度出发，简述了茶废弃物作为原料在提取活性成分以及制备茶渣吸附剂、活性炭、生物有机肥、动物饲料、食用菌培养料等方面的研究进展，并对茶废弃物综合利用的发展趋势进行了展望。笔者认为同时采用多种技术对茶废弃物进行综合利用可提升茶废弃物的利用效率、降低生产成本，最后提出了一种简单实用的综合利用方案，可为实际应用提供参考。
