Researchers in the US and UK have engineered an enzyme that could help solve the problem of PET bottle litter.
The breakthrough is the latest in a series of tantalising research results hinting that certain enzymes and microbes that use them might pave a way to degrade mountains of plastics scrap.
Scientists at the US Department of Energy's National Renewable Energy Laboratory and the University of Portsmouth say they have tweaked a bacterium's enzyme to improve its ability to degrade PET. The natural enzyme is in a bacterium called Ideonella sakaiensis, which researchers recently found was degrading PET in a Japanese waste recycling centre.

A hazardous heap of electronic waste was found by a joint military-police raid at a rubbish recycling plant in Pathum Thani's Lam Luk Ka districtlast month. (Photo by Apichit Jinakul)Since China imposed a ban on its import at the end of last year, electronic waste (e-waste), mainly from the United States and Europe, has had to be diverted to altern...
Processing and recycling waste of electrical and electronic equipment (WEEE) such as computers, TVs, fridges and mobile phones is more important than ever, considering the rapid growth in consumption of these products. Europe was the region that produced the second largest amount of e-waste in 2016 – with 12.3 million tonnes (MT), after Asia ...
ECHA is assessing the need for a REACH restriction on intentional uses of ‘microplastic’ particles. As an outcome of the stakeholder workshop on the intentional uses of microplastic particles held at ECHA on 30-31 May 20181 , ECHA announced that it would publish a note outlining in broad terms what it has learnt about the identification...
The environment committee called for a number of measures that go beyond the Commission’s original proposals, including:i) A ban on microplastics in cosmetics, personal care, detergents and cleaning products by 2020, and minimum requirements to tackle other sources of microplasticsii) A complete ban on oxo-degradable plastics – a source...
The Definition of Solid Waste (DSW) Rule defines under the Resource Conservation and Recovery Act (RCRA) what materials are subject to Subtitle C regulation as discarded solid waste materials, as opposed to those materials appropriate for beneficial reuse and recycling. The regulations at issue have been the subject of several legal challenge...
