Continuous chemical purification process prototype for plastic film derived pyrolysis oil

塑料薄膜对废物和回收行业构成了重大挑战。在塑料污染危机意识已经广泛传播的时候，混合包装薄膜仍然没有可行的工艺。目前的回收方法受到复合材料、添加剂、难以分离聚合物类型以及食品或其他有机或无机材料形式的污染的限制。回收这类薄膜在经济上是不可行的，大多数都被送去焚烧。在2019冠状病毒病期间，这种包装的使用有所增加，一些聚乙烯供应商报告同比增长50%。与此同时，油价下跌降低了包括回收材料在内的所有塑料的价值。在牛津可持续燃料公司，我们开发了新的化学分离和净化方法，以解决现有处理技术的关键挑战。这些新方法的应用将大大增加通过回收混合塑料薄膜产生的价值，创造一个可行的工业过程。

Plastic films represent a significant challenge to the waste and recycling industry. At a time when awareness of plastic pollution crisis has become widespread there are still no viable processes for mixed packaging films.Current recycling methods are limited by the presence of composite materials, additives, difficult to separate polymer types and contamination in the form of food or other organic or inorganic material. The recycling of such films is not economically viable, and the majority are sent to incineration.During Covid19 the use of such packaging has increased, with some polyethylene suppliers reporting 50% year on year growth. At the same time, oil prices have fallen lowering the value of all plastics including recycled material.At Oxford Sustainable Fuels we have developed new chemical separation and purification methods to address key challenges of existing processing technologies. The application of these new methods will significantly increase the value generated through recycling mixed plastics films to create a viable industrial process.
