ABSTRACT
The biomass energy has been recognized as a clean fuel due to its advantages of regeneration, rich resource, carbon neutral, and environmental benignity. Meanwhile, the Chinese materia medica (CMM) residue is a typical biomass. Therefore, the CMM residue converted into energy and recycled for industrial production has been recognized as a higher-value utilization mode. Obviously, this model can not only realize disposal and transformation of residues, but also replace fossil fuels to reduce consumption and increase enterprise profits. The energy utilization strategies of herb residue have been reviewed based on all kinds of strategies such as direct combustion, fermentation for biogas and ethanol, pyrolysis. This paper can provide a reference for further exploiting and developing of higher-value energy utilization mode of herb residue and expanding of resource utilization approaches and levels.
ABSTRACT
With the rapid development of traditional Chinese medicine industry, a large number of Chinese medicine residues were produced as byproducts. A large number of cellulose, protein, lipid and a variety of trace elements in Chinese medicine residues can be used to produce products with new value as the recyclable biomass resources. Chinese medicine residues can be transformed into bio-organic fertilizer through the application of biotechnology, which improves the utilization ratio of these materials. It is a good way to mine potential out of them. On the basis of reviewing domestic and foreign literature, this paper mainly focuses on producing bio-organic fertilizer by making full use of Chinese medicine residues. The practical significance of bio-organic fertilizer research, the value and main ways of recycling residues, the effects of bio-organic fertilizer, the fermentation microbial flora, and the functional microbial flora were described in details in this paper.
