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,

Chemical solutions for greywater recycling
Chemosphere, 2008Greywater recycling is now accepted as a sustainable solution to the general increase of the fresh water demand, water shortages and for environment protection. However, the majority of the suggested treatments are biological and such technologies can be affected, especially at small scale, by the variability in strength and flow of the greywater and ...

Chemically recyclable polyolefin-like multiblock polymers
Science, 2023Polyolefins are the most important and largest volume plastics produced. Unfortunately, the enormous use of plastics and lack of effective disposal or recycling options have created a plastic waste catastrophe. In this work, we report an approach to create chemically recyclable polyolefin-like materials with diverse mechanical properties ...

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.

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.

Shell embraces chemical recycling
C&EN Global Enterprise, 2019Shell Chemical says it has successfully used postconsumer plastics to make chemicals. The Atlanta-based company Nexus Fuels broke down waste plastics into pyrolysis liquid, which was delivered to Shell’s Norco, Louisiana, chemical complex and upgraded into petrochemicals.
