摘要

塑料在现代生活的方方面面无处不在。尽管它很有用，但只有9%的塑料垃圾被回收利用，留下了大量的垃圾填埋场和环境。需要研究使用这种废塑料的新策略。本报告分析了将废塑料升级为膜用于水和气体分离。聚对苯二甲酸乙二醇酯、聚苯乙烯、聚氯乙烯、聚乙烯、聚丙烯和轮胎橡胶已被研究用作膜。未来的工作需要研究更环保的溶剂、健康和安全方面、成本、供应和需求，以及将塑料废物升级为膜的生命周期评估。

Membranes from upcycled waste plastics: current status, challenges, and future outlook

Plastic is ubiquitous across all aspects of modern life. Despite its usefulness, only 9% of all plastic waste ever produced has been recycled, leaving a tremendous amount that ends up in landfills and the environment. New strategies need to investigate using this waste plastic. This report analyzes upcycling waste plastics into membranes for water and gas separations. Polyethylene terephthalate, polystyrene, poly(vinyl chloride), polyethylene, polypropylene, and tire rubber have been studied for use as membranes. Future work needs to investigate greener solvents, health and safety aspects, costs, supply and demand, and life cycle assessments for upcycling plastic waste into membranes.

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
