Although much progress has been made in recycling the easier polymer streams such as at-line production waste, or through specialist closed loop systems, the challenge to recycle Post Consumer polymer waste (mainly packaging from consumer goods such as food, sauces and detergents) is still tough, particularly for polypropylene and polyethylene. These polymers strongly absorb odours from their contents, which currently needs uneconomic levels of cleaning before they can be recycled into high value products such as automotive fascias and building products. Of the UK’s 260,000 tonnes of post consumer polypropylene waste, under 1% is recycled into high quality products; the rest is used in low value applications such as buried geotextiles, or is landfilled or incinerated. The VOCex process concept from Luxus, a recycling compounder for automotive plastics, has been specifically created to provide a cost effective method to deodourise polymers for higher value uses. This proof of concept project is intended to validate the feasibility of the process and its ability to cope with the variability in the type and levels of odour compounds that occur in post-consumer polymer, to underpin our future objectives of scaling it up to commercial application. The future embodiment of the technology is envisaged as a turnkey or retrofit option for Luxus and other existing compounders as licencees, allowing them to provide high quality polymers from materials that would otherwise have been destined for landfill or incineration.

尽管在回收更容易的聚合物流方面取得了很大进展，如生产线上的生产废物，或通过专业的闭环系统，但回收消费后聚合物废物（主要是食品、酱汁和洗涤剂等消费品的包装）的挑战仍然很严峻，特别是聚丙烯和聚乙烯。这些聚合物从其内容物中强烈吸收气味，目前需要不经济的清洁水平，然后才能回收到高价值产品，如汽车筋膜和建筑产品。在英国消费后产生的26万吨聚丙烯废物中，不到1%被回收利用，制成高质量的产品；其余的用于低价值的应用，如埋土工布，或填埋或焚烧。来自汽车塑料回收复合材料Luxus的VOCex工艺概念，专门为高价值用途的聚合物脱氧提供了一种经济有效的方法。这一概念验证项目旨在验证该工艺的可行性及其应对消费后聚合物中气味化合物类型和水平变化的能力，以支持我们未来将其扩大到商业应用的目标。该技术的未来体现被设想为Luxus和其他现有的化合物作为许可方的交钥匙或改造选择，使他们能够从原本要被填埋或焚烧的材料中提供高质量的聚合物。
