MOSCOW (MRC) -- Covestro (formerly Bayer MaterialScience) has recently began operating a pilot plant to demonstrate the process, which depends on an intelligent foam sorting technology. The company has developed an innovative process for the chemical recycling of polyurethane (PU) flexible foam from used mattresses, as per the company's press release.
On average, mattresses contain 15 to 20 kilograms of foam, which results in a large amount of waste at the end of their useful life. The foam is primarily made of two important raw materials. While other chemical recycling approaches mainly focus on processing one of them, the Covestro process now enables the recovery of both raw materials.
Thus, Covestro has recently started operating a pilot plant for flexible foam recycling at its Leverkusen site to confirm the positive laboratory results achieved to date. The first phase is to focus on recycling one of the raw materials, before the recovery of the second component is also to be piloted from summer this year. Covestro?s goal here is to industrialize chemical recycling processes for used flexible foams and ultimately to remarket both recovered raw materials.
In cooperation with the companies Recticel and Redwave – a division of Wolfgang Binder GmbH - and as part of the PUReSmart research project, Covestro has also developed an intelligent sorting solution for separating the different PU foams from post-consumer mattresses. The software uses algorithms to correctly identify the different foam types, which facilitates an effective recycling process. This development is another element of Covestro’s digitalization strategy, combined with the new opportunities it entails for the chemicals and plastics industry.
The project is an important step forward in taking the development of the circular economy at Covestro to entirely new heights. The increased use of used materials further contributes to solving the societal challenge of sustainable disposal of such waste and to achieving the European Union?s goals for the circular economy and for climate and environmental protection.
As MRC reported earlier, Covestro closed the sale of its European polycarbonates (PC) sheets business to the Munich-based Serafin Group effective January 2, 2020. This includes key management and sales functions throughout Europe as well as production sites in Belgium and Italy.
According to MRC's ScanPlast report, Russia's overall consumption of PC granules (excluding exports from Belarus) totalled 8,100 tonnes in January 2021, up by 20% year on year (6,800 tonnes a year earlier).
Covestro (formerly Bayer MaterialScience) is an independent subgroup within Bayer. It was created as part of the restructuring of Bayer AG from the former business group Bayer Polymers, with certain of its activities being spun off to Lanxess AG. Covestro manufactures and develops materials such as coatings, adhesives and sealants, polycarbonates (CDs, DVDs), polyurethanes (automotive seating, insulation for refrigerating appliances) etc. With 2020 sales of EUR 10.7 billion, Covestro has 33 production sites worldwide and employs approximately 16,500 people (calculated as full-time equivalents).
