Sea turtle: Sentinels and victims of plastic pollution in the Adriatic Sea

by

via EurakAlert

Sea turtles are witnesses and victims of the high level of plastic pollution of the Adriatic Sea. A group of researchers at the University of Bologna analysed 45 turtles hospitalised at Fondazione Cetacea in Riccione and found plastic debris in their faeces. Besides confirming the role of turtles as ideal sentinels to monitor plastic pollution in the sea, the results of their analysis – published in the journal Frontiers of Marine Medicine – crucially show how the plastic debris in their intestines can dangerously alter their microbiota, eventually compromising their health.

Fighting the plastics plague, one canoe-full at a time

via the Bay Journal

John Naylor eased his 16-foot fiberglass canoe into the Susquehanna River near a small archipelago of forested and ever-changing mudflat islands known as the Conejohela Flats, once the domain of Native Americans and still a vital stop for migrating shorebirds.

It’s a placid and beautiful spot on the lower Susquehanna between Lancaster and York counties, PA. But the York city resident was there this day to nibble at a growing sheen of ugliness — namely, single-use plastic containers, especially discarded water bottles.

How Paving with Plastic Could Make a Dent in the Global Waste Problem

by

via Yale Environment 360

Roads in which waste plastic is melted down and mixed with paving materials are becoming more common around the world. Although for now they remain a niche technology, experts say the roads could become one of a diverse array of uses for discarded plastic.

Aroad running through Accra, Ghana’s capital, looks like any other blacktop. Yet what most drivers don’t realize is that the asphalt under them contains a slurry of used plastics — shredded and melted bags, bottles, and snack wraps — that otherwise were destined for a landfill.

    Seagrass ‘Neptune balls’ bundle plastic waste

    by

    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.

    Is laundry fuelling the marine plastics crisis?

    by

    via BusinessGreen.com

    Clothing and textiles are a major and underacknowledged source of microplastics pollutions in the world’s oceans, a new study analysing seawater samples from across the Arctic Ocean has found.

    The study revealed that synthetic fibres make up more than 90 per cent of microplastic pollution found in near-surface seawater samples from across the Arctic. Nearly three-quarters of those fibres are polyester and resemble fibres widely used in clothing and textiles, with the bulk of this pollution thought to released during domestic laundry, the research states.

    New process upcycles plastic waste into a more valuable adhesive

    by

    via News Atlas

    A team at UC Berkeley has developed a process that turns plastic waste into something more valuable – an adhesive. Based on an engineered catalyst, the inspiration was to find ways to “upcycle” plastics by putting them to new uses while preserving the properties that made them attractive in the first place.

    Plastic waste is one of the modern world’s biggest environmental concerns, but plastics are notoriously unattractive to recycling companies. Unlike corrugated cardboard, glass, or scrap metal, plastics are very difficult to reuse and doing so makes the end product less valuable than the original plastic – which isn’t very valuable to begin with.

    Oceana report says Amazon has a ‘plastic problem’, pollutes oceans with 22 million pounds of plastics per year

    by

    via Fox29.com

    Oceana analyzed e-commerce and packaging market data as well as a recent scientific report, published in Science about predicted growth in plastic waste and found that Amazon has a large and rapidly growing plastic pollution footprint.

    “Amazon has a plastic problem,” Oceana wrote in the report released on Dec. 15. “Oceana estimates that in 2019, up to 22.44 million pounds of Amazon’s plastic packaging has ended up in the world’s freshwater and marine ecosystems as pollution. This amount is roughly equivalent to a delivery van’s worth of plastic being dumped into major rivers, lakes, and the oceans every 70 minutes.”

    These solar-powered barges can scoop up 50 tons of plastic from rivers each day

    by

    via The Optimist Daily

    While removing the plastic waste that currently contaminates the ocean today will be crucial for protecting marine ecosystems, it is arguably more important that we stop any more plastic trash from entering the ocean. Fortunately for humanity, The Ocean Cleanup, a nonprofit taking on plastic waste in the ocean today, also has a novel solution for stopping plastic from entering it via rivers.

    The solution comes in the form of a solar-powered barge named the “Interceptor”. The 24-meter-long (78 feet) vessel resembles a large houseboat and uses a curved barrier to catch waste floating downstream. The trash, much of it plastic, is directed to the “mouth” of the barge — which operates autonomously and silently — from where it rolls up a conveyor belt and is dropped into dumpsters. Apparently, the Interceptor is capable of collecting up to 50 tons of waste a day.

    Bali’s beaches buried in tide of plastic rubbish during monsoon season

    by

    via The Guardian

    Bali’s famous beaches are being strewn by plastic rubbish in what experts say is becoming an annual event thanks to monsoon weather, poor waste management and a global marine pollution crisis.

    Authorities are struggling to keep up with the tide of rubbish washing up on beaches at Kuta, Legian and Seminyak, where about 90 tonnes of rubbish was collected on Friday and Saturday.

    Plastic waste forms huge, deadly masses in camel guts

    by

    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.
