REMADYL | Removal of Legacy Substances from polyvinylchloride (PVC) via a continuous and sustainable extrusion process

Original description

REMADYL aims at recycling so-called ‘old PVC’, i.e. PVC additivated with hazardous legacy substances (LS) such as low molecular weight phthalate plasticisers (mainly DEHP) and heavy metal based stabilisers (mainly lead). This ‘old PVC’ constitutes most of current hard (e.g. window frames, tubes) and soft (e.g. flooring or cables) PVC post-consumer waste. The presence of LS is a persistent barrier for PVC recycling as there are currently no economically viable solutions for their removal.
To tackle this major challenge, REMADYL will develop a breakthrough single step continuous process based on extractive extrusion technology in combination with novel solvents and melt filtration, which has the potential of rejuvenating ‘old PVC’ into REACH compliant high purity PVC tuned towards the demands of various soft and hard PVC products at market competitive cost (ca €570/ton, CAPEX and OPEX included). The process also has potential for other plastics applications, e.g. removal of (halogenated) flame retardants.
Using this process, REMADYL will demonstrate the circular use of PVC for window profiles and waterproofing sheets, providing a flagship example for the circular economy. The extracted phthalate plasticizers will be safely disposed (with energy valorisation) and the lead will be re-used in batteries.
REMADYL will deliver a breakthrough support to the Circular Economy Package and resource efficiency targets for Europe as recovered PVC will reduce incineration and landfilling. Assuming we recycle 400kton/year of ‘old PVC’ waste within 5 years after REMADYL, this will result in a reduction of ca 800ktons CO2eq and 8ktons lead emissions. This also implies the creation of ca 800 new jobs and a turnover of ca €280million. Safety aspects will be studied, leading to best practices, standardisation input and policy recommendations.
REMADYL consortium consists of 15 multidisciplinary partners, including 9 companies, and covers all expertise to maximise project impact.
