Catalytic deconstruction of waste polyethylene with ethylene to form propylene

Science, 2022
The conversion of polyolefins to monomers would create a valuable carbon feedstock from the largest fraction of waste plastic. However, breakdown of the main chains in these polymers requires the cleavage of carbon–carbon bonds that tend to resist ...

Design for deconstruction using a circular economy approach: barriers and strategies for improvement

, 2020
This study explores the current practices of Design for Deconstruction (DfD) as a strategy for achieving circular economy. Keeping in view the opportunities accruable from DfD, a review of the literature was carried out and six focus group interviews ...

Deconstruction of Polymers through Olefin Metathesis.

Chemical Reviews
The consumption of synthetic polymers has ballooned; so has the amount of post-consumer waste generated. The current polymer economy, however, is largely linear with most of the post-consumer waste being either landfilled or incinerated.
