"Whilst plastic packaging recycling rates have been improving across Europe they still remain low at only 35%. With tough new government targets to come into force requiring 65% of plastic waste to be recycled it is essential new technologies are developed to allow recyclers to extract value from this waste economically and meet these targets. Currently this value has come from simply separating plastics into material groups with the majority of material being of mixed colour. Our project aims to develop a new method for extracting value form this waste plastic by developing a process which can remove the pigment dispersed within the plastic returning it to a natural-recyclate. In doing this recyclers would be able to double the resale value of their mixed coloured plastics making more waste economically viable to recycle and giving manufacturers, molders and producers access to greater quantities of natural-recyclate for use in products.The project will build on a previously successful InnovateUK feasibility study which showed pigment could be removed from PE and PP at a lab scale using a novel designer solvent and high-shear mixing technique. Our consortium will target removing pigments from waste plastic packaging which makes up approximately 85% of plastic waste and develop this technology (PolyMet) through to a demonstration plant scale at TRL7 ready for full scale setup post project.This technology fits well within the UK governments new regulatory push for improved recycling in the next decade and will place the UK at the forefront of plastic recycling.The environmental and social benefits from this technology are significant: increased recycling rates will reduce plastic's carbon foot print by reducing our reliance on new plastic production and reduce waste plastics leaking into the environment through poor waste management. There is also a significant trickle down effect into the circular economy with a recent Deliotte study showing that 75 jobs were created for every 10,000 tonnes of recycle produced.Ultimately PolyMet will allow recyclers to realise the maximium value from their feedstocks, allowing it to be used in a greater number of secondary application and allowing our society to move closer to a plastic circular economy."

虽然整个欧洲的塑料包装回收率一直在提高，但仍然很低，只有35%。随着严格的新政府目标即将生效，要求回收65%的塑料垃圾，开发新技术至关重要，使回收商能够经济地从这些废物中提取价值，并实现这些目标。目前，这一价值来自于将塑料简单地分成不同的材料组，其中大多数材料是混合颜色的。我们的项目旨在开发一种新的方法来从这种废塑料中提取价值，方法是开发一种工艺，可以去除分散在塑料中的颜料，将其返回自然回收。通过这样做，回收商将能够使他们的混合颜色塑料的转售价值翻一番，使更多的废物在经济上可行地回收，并使制造商、注塑商和生产商能够获得更多的天然回收物用于产品。该项目将建立在之前成功的InnovateUK可行性研究的基础上，该研究表明，可以在实验室规模上使用一种新型的设计溶剂和高剪切混合技术从PE和PP中去除颜料。我们的联合体将致力于从占塑料垃圾约85%的废塑料包装中去除颜料，并将这项技术(PolyMet)开发到TRL7的示范工厂规模，准备进行全面的安装后项目。这项技术非常适合英国政府在未来十年改进回收的新监管推动，并将使英国处于塑料回收的前沿。这项技术的环境和社会效益是显著的：提高回收效率将通过减少我们对新塑料生产的依赖来减少塑料的碳足迹，并通过糟糕的废物管理减少泄漏到环境中的废塑料。循环经济也有显著的涓滴效应，德勤最近的一项研究显示，每生产10,000吨回收物，就会创造75个就业机会。最终，PolyMet将使回收商从他们的原料中实现最大价值，使其能够被用于更多的二次应用，并使我们的社会更接近塑料循环经济。
