可降解塑料与餐厨垃圾厌氧消化的研究进展

Research Progress of Degradable Plastics and Anaerobic Digestion of Food Waste

随着国家“禁塑令”以及各省对塑料污染物治理相关政策的出台,推广和使用可降解塑料材料成为推动中国塑料污染治理工作的重要环节;同时,垃圾分类投放过程中居民仍普遍存在餐厨垃圾与塑料袋混合投放的问题,为进一步实现城市固体废弃物减量化、资源化,进行可降解塑料与餐厨垃圾同步厌氧消化处理是当前环境、材料等领域研究的趋势和热点。该文结合国内外餐厨垃圾和可降解塑料厌氧消化处理的研究进展,分析了可降解塑料与餐厨垃圾厌氧共消化处理的可行性,并结合实际情况对厌氧共消化技术提出相关建议。

With the introduction of the national“plastic ban order”and the relevant policies on plastic pollution control,the promotion and use of degradable plastic materials has become an important link in promoting the plastic pollution in China;at the same time,during the garbage classification and release process,residents still have the problem of mixing food waste and plastic bags,in order to further realize the reduction and recycling of municipal solid waste The simultaneous anaerobic digestion of degradable plastics and food waste is the trend and hotspot in the field of environment and materials.In this paper,combined with the global research progress of food waste anaerobic digestion and degradable plasticsm,the feasibility of anaerobic co digestion treatment of degradable plastic and food waste was analyzed,and relevant suggestions were put forward according to the reality.
