New polymer recycling technology

聚烯烃、苯乙烯树脂、聚对苯二甲酸乙二酯和聚氯乙烯占消费废塑料流量的90%。在最好的情况下，只有30%的传统热塑性聚合物，即高密度聚乙烯、聚丙烯和聚对苯二甲酸乙二醇酯在北美通常被回收。由于大多数塑料彼此不相容，不同回收塑料的混合物由于相容性差而表现出非常差的机械性能。对大量混合在一起的消费塑料垃圾进行识别、分类和分类是昂贵的，有时甚至是不可能的。这对塑料回收行业造成了严重的限制。 这项建议的目的是研究一种新的塑料回收方法的商业潜力，并将该技术应用于从北美一些最重要的回收公司(加拿大纤维和QRS)获得的实际回收塑料。基于聚合物共混材料科学的最新发展，我们提出了一种新材料及其制备方法。从回收聚乙烯(PP)和回收聚丙烯(PE)的共混开始，当主要PE/PP界面增容时，分级封装聚合物(2-7类废塑料)可以专门放置在PP中。这种可控制的分离和封装高达40%的废塑料在回收聚丙烯中允许创建一种共混的回收塑料材料，具有类似于纯聚丙烯的优异的机械性能。我们的主要目标是获得这种材料的物质组成以及加工技术的许可，本项目结束时的总体目标是获得至少两种可能的再生塑料产品，这些产品具有足够的可行商业潜力来吸引客户投资。

Polyolefins, styrenic resins, polyethylene terephtalate, and polyvinylchloride, represent 90% of the consumer waste plastic stream. In the best scenario, only 30% of traditional thermoplastic polymers, that is, high-density polyethylene, polypropylene, and polyethylene terephthalate are commonly recycled in North America. Since most plastics are immiscible with each other, mixtures of different recycled plastics demonstrate very poor mechanical properties due to the poor compatibility. The identification, separation and sorting of the vast volumes of co-mingled consumer plastic waste into single components is costly and sometimes impossible. This imposes a serious limitation on the plastics recycling industry. The objective of this proposal is to examine the commercial potential of a novel plastics recycling approach and to apply the technology to actual recycled plastics obtained from some of the most important recycling companies in North America (Canada Fibers and QRS). We propose a new material, based on the latest developments in polymer blend material science, and the process for preparing it. Starting from a co-continuous blend of recycled polyethylene (PP) and recycled polypropylene (PE), hierarchically encapsulated polymers (category 2-7 waste plastics) can be exclusively located within PP when the principal PE/PP interface is compatibilized. This controlled segregation and encapsulation of up to 40% of waste plastic within recycled polypropylene allows for the creation of a co-mingled recycled plastic material with excellent mechanical properties similar to pure polypropylene. We principally aim to license the composition of matter, as well as the processing know how, for this material and the overall objective at the end of this project is to obtain at least two possible recycled plastic products that demonstrate sufficient viable commercial potential to attract client investment.
