The food manufacturing sector has been producing multi-layered packaging since the 1970s. Multi-layered packaging offers a combination of properties that one polymer alone cannot provide (e.g. moisture, oxygen, light barrier, stiffness, clarity, gloss etc); typically comprised of layers of PET/PP/PE/PA. Over 40m tonnes p.a. of multilayered plastics are produced globally, of which the EU contributes 9.6m tonnes, with an expected growth of ~7%. However, due to the extreme difficulties in achieving effective separation of the multi-layered packaging into its constituent solid polymer components, there are no current technologies or operational processing plants for solid separation & recovery of the polymer fractions. As a consequence, multi-layered, flexible plastic waste is currently collected as a single waste stream & disposed of through landfill (at costs of £100/t), or incinerated (~£60/t); generating global economic losses of £2.4-4 billion. Disposal of such large volumes of plastic also generates great environmental concern, with an urgent need to develop effective separation technology. Our objective is to develop a novel recycling method to separate multilayered plastic packaging waste. Successful development of this technology will create the business opportunity to recycle this material, generating new revenues while reducing waste, landfill, energy & reducing annual CO2 emissions. Our novel process will not only ensure the sustainable supply of these plastics as raw materials via recycling but will also provide participating SMEs with the opportunity to derive an ongoing income.

自20世纪70年代以来，食品制造业一直在生产多层包装。多层包装提供了单一聚合物无法提供的综合性能(例如，水分、氧气、阻光性、硬度、透明度、光泽度等)；通常由PET/PP/PE/PA层组成。每年超过4000万吨。全球生产的多层塑料中，欧盟贡献了960万吨，预计增长约7%。然而，由于实现将多层包装有效分离成其组成的固体聚合物组分的难度极大，目前还没有用于固体分离和回收聚合物组分的现有技术或操作加工厂。因此，多层、可弯曲的塑料垃圾目前被收集为单一废流，通过垃圾填埋场处置(成本为100 GB/吨)或焚烧(约60 GB/吨)；造成全球24-40亿GB的经济损失。处理如此大量的塑料也引起了极大的环境问题，迫切需要开发有效的分离技术。我们的目标是开发一种新的回收方法来分离多层塑料包装垃圾。这项技术的成功开发将创造回收这种材料的商机，在减少废物、垃圾填埋、能源和减少年度二氧化碳排放的同时，创造新的收入。我们的新工艺不仅将通过回收确保这些塑料作为原材料的可持续供应，而且还将为参与的中小企业提供获得持续收入的机会。
