摘要
生物转化过程具有条件温和、过程绿色、产品高值等优势,是未来废弃物高值化利用的重要途径。塑料是人工合成的有机高分子材料,已作为基础材料融入人类生活的方方面面。而海量剧增的废弃塑料已造成严重的环境污染与资源浪费。由于废弃塑料组分复杂、降解能垒高、胁迫因子多、回收经济性差,单一的生物技术尚无法对其进行即时处理,因此,基于学科交叉与过程集成,综合利用多种废塑料回收技术,建立多元化、个性化、交叉化的塑料回收新路线成为提升我国废弃塑料资源回收与利用水平、发展循环经济的重要途径。本文以生物技术为核心,综述了目前生物-物理、生物-化学以及生物-信息等技术交叉在塑料废弃物回收方面的研究进展,并针对性地分析了学科交叉研究中存在的瓶颈,探讨了未来亟需攻克的技术难点,以期为废塑料的高效回收利用提供新的思路和理论指导。
Owning to the advantages of mild conditions,green process and high valuable,biotransformation will become an important approach for waste recycling in the near future.Plastics are synthetic organic polymer materials,which have been widely used in human daily life.However,the massive accumulation of waste plastics has caused a serious environmental pollution and huge resources waste.Due to the complex degraded fractions,high degradation energy barrier,multifarious stress factors and poor recycling economy regard to waste plastics recycling,a single utilization of biotechnology is not yet able to deal with them in real time.Therefore,based on interdisciplinary and process integration,coupling the use of a variety of technologies for waste plastic recycling,so that to establish a diversified,personalized and crossed new route for waste plastic recycling,has become the key to improve the recycling and utilization level of waste plastics resources and develop a circular economy in China.This paper summarized the current research progress of multi-disciplinary combined technology launched around biotechnology during waste plastics recycling,including biological-physical,biological-chemical and biological-informationalized cross-used technologies,with emphasis on the bottlenecks lying in interdisciplinary research,aiming to provide new ideas and theoretical guidance for construction of a more efficient route to waste plastics recycling.
