Marine pollution: How do plastic additives dilute in water and how risky are they?

via Science Daily

New research shows that additives in plastic materials deployed or thrown in coastal environments diffuse into the environment at different rates. Their findings demonstrate how assessments of exposure risk based on the composition of the source plastic waste will be inaccurate, because this composition varies as plastics break down and additives dilute into the environment at different rates. A new evaluation method is needed, and these scientists have just the solution.

Plastic pollution has been at the center of environmental debate for decades. While it is well-known that plastic in the environment can break down into microplastics, be ingested by humans and other organisms, transfer up the food chain, and cause harm, this is only one part of the picture. Plastics are almost always enriched with additives, which makes them easier to process, more resistant, or more performant. This poses a second problem: when the polymer material is left in an environment for long durations, these additives can easily leach out and contaminate the environment.

Welsh government backs project to turn waste plastic into carbon nanotubes

via Circular

The Welsh government is backing a cutting-edge science project at Swansea University that changes waste plastics into highly valuable compounds for the energy industries.

The government is to invest in a plastics upscaling project which has the potential to create highly-skilled jobs in Wales, the university says.

Scientists are extracting carbon atoms found in waste plastics and turning them into a nanotube format that can be used for the transmission of electricity.

Plastic waste forms huge, deadly masses in camel guts

via Science News

Marcus Eriksen was studying plastic pollution in the Arabian Gulf when he met camel expert Ulrich Wernery. “[Ulrich] said, ‘You want to see plastic? Come with me.’ So we went deep into the desert,” Eriksen recalls. Before long, they spotted a camel skeleton and began to dig through sand and bones.

“We unearthed this mass of plastic, and I was just appalled. I couldn’t believe that — almost did not believe that — a mass as big as a medium-sized suitcase, all plastic bags, could be inside the rib cage of this [camel] carcass,” says Eriksen, an environmental scientist at the 5 Gyres Institute, a plastic pollution research and education organization in Santa Monica, Calif.

More than 1.56 billion face masks could end up polluting oceans: report

via CTV

TORONTO — More than 1.56 billion face masks used in 2020 will make their way into our planet’s oceans, joining literal tonnes of other plastic pollution, according to an estimate by OceansAsia.

The Hong-Kong based marine conservation organization released a report on Monday that details one of the devastating side-effects of the COVID-19 pandemic: the increase in plastic use and disposal.

Coca-Cola, Pepsi and Nestlé named top plastic polluters for third year in a row

via The Guardian

Coca-Cola, PepsiCo and Nestlé have been accused of “zero progress” on reducing plastic waste, after being named the world’s top plastic polluters for the third year in a row.

Coca-Cola was ranked the world’s No 1 plastic polluter by Break Free From Plastic in its annual audit, after its beverage bottles were the most frequently found discarded on beaches, rivers, parks and other litter sites in 51 of 55 nations surveyed. Last year it was the most frequently littered bottle in 37 countries, out of 51 surveyed.

Java’s protective mangroves smothered by plastic waste

via Royal Netherlands Institute for Sea Research

The mangrove forests on Java’s north coast are slowly suffocating in plastic waste. The plastic problem in northeast Asia is huge and a growing threat to the region’s mangroves; a natural ally against coastal erosion. Based on fieldwork published in Science of the Total Environment, NIOZ researcher Celine van Bijsterveldt shows that restoration of this green protection belt is impossible without better waste management.
