Nature bites back: Scientists modify plastic-digesting enzyme

Professor Adisa Azapagic of the University of Manchester, UK, likewise agreed that the enzyme could prove useful, but stated concern that it could lead to other forms of pollution: "A full life-cycle assessment would be needed to ensure the technology does not solve one environmental problem - waste - at the expense of others, including additional greenhouse gas emissions".

The researchers are now working with the tools of protein engineering and evolution to improve the enzyme in order to allow it to be used industrially to break down plastics in a fraction of the time.

Developing countries signed up to the Alliance will also be eligible to bid for partnership support to improve waste management systems and implement other initiatives to stop plastic waste from reaching oceans, a press statement said.

Lead scientist prof John McGeehan, from Portsmouth university, said: 'Serendipity often plays a significant role in fundamental scientific research, and our discovery is no exception.

"That's really exciting because that means that there's potential to optimise the enzyme even further".

PET, patented as a plastic in the 1940s, has not existed in nature for very long, so the team set out to determine how the enzyme evolved and if it might be possible to improve it.

Professor McGeehan said: "The engineering process is much the same as for enzymes now being used in bio-washing detergents and in the manufacture of biofuels - the technology exists and it's well within the possibility that in the coming years we will see an industrially viable process to turn PET and potentially other substrates like PEF, PLA, and PBS, back into their original building blocks so that they can be sustainably recycled".

BREAKING Allegiant's high number of mechanical issues featured on 60 Minutes
A flight on June 17, 2015, from Tampa Bay to Pittsburgh, where a plane turned back because of a problem with its air conditioner. It is unfortunate and disappointing that CBS 60 Minutes has chosen to air a false narrative about Allegiant and the FAA.

"Enzymes are non-toxic, biodegradable and can be produced in large amounts by microorganisms", he said.

Dr Colin Miles, Head of Strategy for Industrial Biotechnology at BBSRC, added: "This is a highly novel piece of science based on a detailed molecular-level understanding of an enzyme able to depolymerise a common type of plastic, whose persistence in the environment has become a global issue".

Together with CCOA joint chair Vanuatu, UK said it will urge other countries to ban use of microbeads, cut down on single use plastic bags, or take steps to eliminate avoidable plastic waste.

The Ministry of Environment, Forest and Climate Change has recently notified the amendments in Plastic Waste Management Rules 2018.

"The UK public has shown passion and energy in the fight against plastic waste". And according to the Earth Institute at Columbia University, only 9.5 percent of plastic is recycled and there are already 165 million tons of plastic debris in our oceans.

16 April 2018 -- In the United States, over a five year period between 2011 and 2016, cold brew coffee consumption soared by more than 500 percent - and now it's growing rapidly across Europe.
