recycling waste plastics for circular economy important. currently recycling methods to 诸如社会观念, and technology and other issues heavy heavy retardant 碍; however, in year 里, improvement polymer recycling utilizing innovation technology formed amount large increase.

this 篇文章 introduction main/primary recycling methods, this methods has solution in IDTechEx(UK 剑桥) most new report in, Bryony Core博士提出 about/regarding waste plastics issues.

material or chemical process

polymer recycling can separation is material or chemical process. in material process in, polymer and other polymer or separation process 依赖于 its material property 质, melting point or solvent understanding degree. although polymer in process in can can chemical 变化, this is 无心之失, non pure polymer main/primary 目. recycling methods is machine recycling, it 依靠人工 or optical methods remove other polymer or can recycling material and other 杂质, rear will polymer abrasion 碎, 熔化并 pelletizing.

machine recycling disadvantages

machine recycling disadvantages is front separation 选不精确, easy mixed 入杂质. tube/pipe already measures through new optical separation technology (例如近红 outer) improve/increase remove rate, decrease/reduce key/critical in generate waste material 本身, in generate will its positive type is separation. make add polymer has 污染, add hot polymer loss recycled polymer property can, is add hot bad certain polymer structure.

new process

this issues add upper other 经济考虑 factors, already formed is recycling utilizing 障碍; however, in polymer recycling field/area innovation positive in solution improve/increase recycling polymer quality technology 障碍. this new process separation is type: solvent agent 萃取, plastics is material or understanding poly reaction. solvent agent is material process, it 依赖于 target/goal polymer in different in solvent understanding degree different. to currently is 止, in year 里, already has 一 初创 enterprise development recycling polymer (包括 waste polyester fiber material) process.

another process, from plastics to material and understanding poly, is chemical recycling methods. chemical recycling utilizing 依赖于 through reaction will waste polymer is chemical property different product. more formed technology, plastics to material 转换, use mixed combined polymer waste material, use chemical reaction (例如 hot understanding or gas 化)输出燃 material separation, very difficult again ring.

about/regarding understanding poly reaction

new understanding poly reaction, and polymer most formed methods positive good versus 反: polymer by hot understanding or catalytic separation understanding, can used as combined formed polymer raw materials, can is other has use chemical in 间体. understanding poly reaction especially 令人振奋, is it provide types new obtain polymer, has in other recycling methods in to disadvantages: polymer tool has same property can, and for material tool has resistant property.

very obvious, for/regarding already to use lifespan polymer, need waste material tube/pipe agreement. although its in 一 挑战 源于经济 and 社会, development new process solution improve/increase full polymer recycling rate technology 障碍, will large circular economy 进程.
