UC Berkeley researchers have developed a groundbreaking catalytic process that converts plastic waste into valuable materials ...

Two years ago, Hartwig and his UC Berkeley team came up with a process for breaking down polyethylene plastic bags into the monomer propylene—also called propene—that could then be reused to ...

The global polypropylene compounds market revenue was around US$ 17.2 billion in 2022, and the polypropylene compounds industry is estimated to reach US$ 29.7 billion by 2031, growing at a compound ...

Two years ago, Hartwig and his UC Berkeley team came up with a process for breaking down polyethylene plastic bags into the monomer propylene -- also called propene -- that could then be reused to ...

The resulting output is propylene and propene molecules. Another byproduct is valuable isobutylene gas. All three are used in the chemical industry to make different plastics. For instance ...

Polymerisation is the process in which many small monomer units combine to form one large polymer molecule. The alkenes ethene and propene are two important feedstocks in the petrochemical ...

The reactions run at 320 °C and produce a mix of ethene, propene, and isobutene, which could be teased apart by standard industrial cryogenic separations. It takes about 90 minutes to convert 1 g of ...

The catalytic process efficiently breaks down polymers into chemical precursors, advancing the development of a circular ...

The same reaction occurs with polypropylene to form a combination of propene and a hydrocarbon called isobutylene. Isobutylene is used in the chemical industry to make polymers for products ...

At the University of California, Berkeley, a new chemical process claims to 'essentially vaporize' polyethylene, ...

Compounds such as ethanol, lactic acid, succinic acid and glycerol would then replace — or at least reduce our reliance on — fossil-based compounds such as ethene, propene, butadiene and benzene.

Ernst and colleagues used this approach to switch the chirality of a propene (C 3 H 6) molecule adsorbed on a copper surface. To gain further insight into the switching process, the researchers ...
