中药渣资源化利用探讨

Discussion on resource utilization of herb residues

我国是中药生产大国,每年产生的中药渣超过3 000万吨,直接或间接排放处理不仅浪费资源,而且还会导致严重的环境污染问题。中药渣中残留大量的纤维素、蛋白质、脂质及其他多种微量元素,是一种可循环利用的生物质资源,可用于生产有新价值的产品。中药渣的绿色转化可为中药相关企业带来可观的经济效益。本文从中药渣有效成分富集提取分离、生态经济化利用、高附加值化利用3个方面对中药渣的资源化利用进行分析、综述。

China has been known as a country abounds with traditional Chinese medicine production. More than thirty million tons of herb residues has been generated and disposed directly or indirectly every year, which not only wasted a large of natural resource, but also caused a series of serious environmental problems. Herb residues are full of cellulose, protein, lipid, and other various microelements, which, as a kind of recyclable resources, can be used to produce some new valuable products. Moreover, it also can bring significant economic benefits if we make green use of herb residues. In this paper, we will review the related literatures in separation and extraction of active ingredients from herb residues, ecological economic utilization and high value-added use of herb residues.
