Scientists unveil bionic robo-fish to remove microplastics from seas

via The Guardian

Scientists have designed a tiny robot-fish that is programmed to remove microplastics from seas and oceans by swimming around and adsorbing them on its soft, flexible, self-healing body.

Microplastics are the billions of tiny plastic particles which fragment from the bigger plastic things used every day such as water bottles, car tyres and synthetic T-shirts. They are one of the 21st century’s biggest environmental problems because once they are dispersed into the environment through the breakdown of larger plastics they are very hard to get rid of, making their way into drinking water, produce, and food, harming the environment and animal and human health.

Plastics to outpace coal’s greenhouse gas emissions by 2030 -report

WASHINGTON, Oct 21 (Reuters) – The carbon-intensive production of plastics is on pace to emit more greenhouse gases than coal-fired power plants within this decade, undercutting global efforts to tackle climate change, a report released on Thursday said.

The report by Bennington College and Beyond Plastics projected that the plastic industry releases at least 232 million tons of greenhouse gases each year throughout its lifecycle from the drilling for oil and gas to fuel its facilities to incineration of plastic waste. That is the equivalent of 116 coal-fired power plants.

Bubble Curtain Technology Prevents Entry Of 500 Tonnes Of Plastic Waste In Yamuna River

via The Logical Indian

In a bid to address the growing menace of plastic pollution in the water bodies, Geocycle India—the in-house waste management arm of Ambuja Cements Limited and ACC Limited, has been doing enormous efforts to collect and co-process the plastic waste in the country. The company implemented bubble curtain technology in April 2021 to stop plastic from entering the river Yamuna in Agra. Now, it has successfully managed to thwart 500 tonnes of plastic waste leakage in the river within a span of just six months. The collected waste will now be processed within Ambuja and ACC plants, as per India CSR.

New Road Pavement Mixture Designed to Incorporate Plastic Waste

via KPCW.org

Each year in the US, millions of tons of plastic waste are discarded and not recycled, leading to serious environmental problems. In an effort to help keep this waste from ending up in the environment, University of Missouri engineers are partnering with Dow and the Missouri Department of Transportation (MoDOT) to design a new road pavement mixture using plastic waste.

    Seagrass ‘Neptune balls’ bundle plastic waste

    via Phys.Org

    Underwater seagrass in coastal areas appear to trap bits of plastic in natural bundles of fibre known as “Neptune balls,” researchers said Thursday.

    With no help from humans, the swaying plants—anchored to shallow seabeds—may collect nearly 900 million plastic items in the Mediterranean alone every year, they reported in the journal Scientific Reports.

    New enzyme cocktail digests plastic waste ‘six times faster’

    via Circular

    The scientists who re-engineered the plastic-eating enzyme PETase have now created an enzyme ‘cocktail’ which can digest plastic up to six times faster.

    A second enzyme, found in the same waste dwelling bacterium that lives on a diet of plastic bottles, has been combined with PETase to speed up the breakdown of plastic.

    Plastic trash flowing into the seas will nearly triple by 2040 without drastic action

    An ambitious plan, two years in the making, might have the solution.

    via National Geographic

    THE AMOUNT OF plastic trash that flows into the oceans every year is expected to nearly triple by 2040 to 29 million metric tons.

    That single, incomprehensibly large statistic is at the center of a new two-year research project that both illuminates the failure of the worldwide campaign to curb plastic pollution and prescribes an ambitious plan for reducing much of that flow into the seas.

    Kauai Artists Collaborate With Nature For Marine Debris Projects

    via Honolulu Civil Beat

    Ghost nets and plastic fragments are becoming collectibles as artists turn the trash into works of art.

    Plastic bags and straws cause countless marine fatalities as their small size, shine and color are an irresistible lure to birds, fish, and turtles. But the most lethal plastic products in the North Pacific are the fishing nets and gear purpose-built to catch and kill marine wildlife. These nets, which can stretch 6 miles in length, comprise about half of the plastic garbage in the Patch. But on Kauai, fishing nets account for almost 90% of marine debris that washes in with the tides.

    Artists sensitive to this disaster have started to look at ghost nets and fragments of plastic as raw material for their creativity. Only 10% of plastic on average is recycled. This leaves a tsunami of synthetic waste to pollute our most precious natural places and resources. They hope their work can bring focus to the problem.
