Chemical Recycling of Polyurethanes and Applications for the Recyclates
Journal of Cellular Plastics, 1998The recycling of thermoset materials, including polyurethane, has always posed unique challenges. Traditional approaches to recycling such materials include mechanical regrinding and the use of the regrind as filler. Chemical recycling of polyurethanes by such means as hydrolysis, aminolysis, and glycolysis, is for the most part considered economically

Chemically Recyclable Ester-Linked Polypropylene
Journal of the American Chemical Society, 2022Polyolefins represent the largest class of commodity materials due to their excellent material properties; however, they have limited pathways to chemical recycling and are often difficult to mechanically recycle. Here we demonstrate a new catalyst for the isoselective copolymerization of propylene and butadiene capable of favoring 1,4-insertion over 1,

Economically and environmentally sustainable closed–loop chemical recycling of polyurethanes has been a goal of the polyurethanes industry for many years. This paper shows how the ultimate recovery and recycling have been integrated into the design of a novel polyurethane cushioning material which still meets all the performance requirements of today.

Advances in the Synthesis of Chemically Recyclable Polymers
Chemistry – An Asian Journal, 2023AbstractThe development of modern society is closely related to polymer materials. However, the accumulation of polymer materials and their evolution in the environment causes not only serious environmental problems, but also waste of resources. Although physical processing can be used to reuse polymers, the properties of the resulting polymers are ...

Big firms are rolling out more chemical recycling initiatives as they face public pressure to act on the plastic waste issue. Unlike mechanical recycling, which primarily sorts and washes plastic waste for reprocessing into plastic goods, chemical recycling breaks the waste into its raw materials so they can be made into virgin plastic again.

Recycling Biowaste and Residuals into Chemical Products
Today, organic chemical products are predominantly produced based on fossil raw materials. The demand for climate-friendly products, legal requirements and the EU emissions trading scheme (EU-ETS) are forcing the chemical industry to focus on increased recycling and production based on CO2 and biomass in the future.Thomas, Bayer +2 more
