中药废弃物的能源化利用策略

生物质能具有可再生、资源丰富、碳中性、环境友好等优点,将典型生物质的中药废弃物高附加值转化为能源,循环应用于工业生产,既可实现废弃物的处理转化,又能达到取代化石燃料、节能降耗、增加企业利润的目的。分析中药废弃物能源化的利用策略(直接燃烧、发酵制沼气和乙醇、热解气化等),为后续深入探索和开发中药废弃物的能源高值化利用模式及拓展资源的利用途径和层次提供参考。

Strategies for energy utilization of Chinese materia medica residue

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.
