New super-enzyme eats plastic bottles six times faster. A super-enzyme that degrades plastic bottles six times faster than before has been created by scientists and could be used for recycling within a year or two.
The super-enzyme, derived from bacteria that naturally evolved the ability to eat plastic, enables the full recycling of the bottles. Scientists believe combining it with enzymes that break down cotton could also allow mixed-fabric clothing to be recycled. Today, millions of tonnes of such clothing is either dumped in landfill or incinerated. Plastic pollution has contaminated the whole planet, from the Arctic to the deepest oceans, and people are now known to consume and breathe microplastic particles.
It is currently very difficult to break down plastic bottles into their chemical constituents in order to make new ones from old, meaning more new plastic is being created from oil each year. The 2018 work had determined that the structure of one enzyme, called PETase, can attack the hard, crystalline surface of plastic bottles. What is the #CleanCoasts team up to this #WorldOceansDay?

Over half of consumers say they have reduced the amount of disposable plastic they are using in the last year, according to a report which praises the ‘Attenborough effect’.
The report claims that awareness raising initiatives over the last 12 months, including ‘David Attenborough’s acclaimed TV series Blue Planet II and Our Planet, released on Netflix on April 5th’, are having a positive impact in changing people’s behaviour. According to the study of 3,833 consumers by GlobalWebIndex into sustainable packaging in the UK and US, 42 per cent of consumers say products that use sustainable materials are important when it comes to their day-to-day purchases. In the UK, 82 per cent of respondents who value sustainable packaging say it’s important to them because they’re concerned about the future of the environment. Beyond a general concern for the environment, in the UK, motivations for buying sustainable packaging are more self-directed; focused on a personal desire to be less wasteful.
