A French company uses enzymes to recycle one of the once-used plastics


Because single-use plastics are derived from oil, by 2050 Plastics can account for 20% of global oil production. Reducing our dependence on plastic, and finding ways to use plastic that is already in the world, can reduce emissions.

Right now, almost 15% of all plastics all over the world are taken for use every year. Researchers have been trying since the 1990’s to find new ways to destroy plastics with the hope of recycling more. Companies and researchers have worked to develop enzymatic processes, such as those used in Carbios, as well medical procedures, as a means Loop Companies. But recently enzymatic and pharmaceutical methods have begun to sell.

The new Carbios machine measures 20 cubic meters – around the size of a freight car. It can hold up to two tons of plastic, or the equivalent of 100,000 bottles at a time, and break down PET buttons – ethylene glycol and terephthalic acid — for 10 to 16 hours.

The company plans to use what it learns from the exhibition space to make its first corporate plant, which has a camera that is about 20 times larger than the show. The whole plant will be built near a plastic manufacturer somewhere in Europe or the US, and is expected to be operational by 2025, he said. Alain Marty, Master of Carbios science.

Carbios has been developing enzymatic regeneration since the company was founded in 2011. Its method relies on enzymes to break long chains of polymers that make plastics. The results can be refined and blended to form new plastics. Researchers at Carbios started with natural enzymes that bacteria use to break down leaves, and then refine them to be very effective in breaking down PET.

Carbios estimates that its nutrient rehydration method reduces greenhouse gas emissions by about 30% compared to virgin (newly made, unmodified) PET. Marty says he expects the number to increase as he repairs kink.

Soon reports, the researchers think that making PET from regenerative enzymatic can reduce greenhouse gas emissions by 17% to 43% compared to virgin PET production. The report was not about Carbios, but it is probably an accurate comparison, according to Gregg Beckham, a researcher at the US National Renewable Energy Laboratory and co-author of the report.

While the development of new enzymes has been a major focus of new research and commercial applications, some aspects of the process will show how the technology can be both effective and cost-effective, says Beckham, lead director. agreement on new methods of plastic manufacturing and manufacturing.

“Everything is not really good,” Beckham says, like making plastic in a form in which enzymes can break down or separate what the enzymes spit out, which can take a lot of energy and time, and drive air and money.
