Chemists have developed a catalytic process that turns the largest component of today's plastic waste stream, polyolefin plastic bags and bottles, into gases -- propylene and isobutylene -- that are ...

Soon, however, it may be possible to recover high-grade polypropylene from synthetic carpets that would otherwise just end up in the dump. The new recycling process is being developed by scientists at ...

A new process to recycle existing plastics indefinitely and reduce the flood of plastics into landfills is being developed by scientists at the University of California, Berkeley. From sandwich bags ...

While millions of tons of plastic are produced in the US each year, only around 9 percent is recycled, and that is largely due to the difficulties around reducing the material to useful building ...

Water used to wash recycling materials in the study became progressively darker as it was reused. Photo courtesy of Greg ...

With a new process, ENGEL makes it possible to process plastic waste as flakes in injection molding directly after grinding. Since pelletizing as a separate process step is eliminated, the innovation ...

Lindner shredding system in Lithuania helps process polypropylene plastic “big bag” bulk shipping sacks. Big bags, also known as FIBCs, are usually made of polypropylene and are designed for ...

Big brands like Procter & Gamble and Nestlé say a new generation of plants will help them meet environmental goals, but the technology is struggling to deliver. Big brands like Procter & Gamble and ...

Graduate student RJ Conk adjusts a reaction chamber in which mixed plastics are degraded into the reusable building blocks of new polymers. A new chemical process can essentially vaporize plastics ...
