  1. #Neuralnetwork finds an #enzyme that can break down #polyurethane
    A completely new enzyme that researchers developed to break down polyurethane, the #polymer commonly used to make #foam cushioning, among other things. The new enzyme is compatible with an industrial-style recycling process that breaks the polymer down into its basic building blocks, which can be used to form fresh polyurethane.

  6. #MarineFungi Could Eat #PlasticPollution, Helping to Clean Our #Oceans and #Beaches

    Learn more about the marine #fungi that could be conditioned to help clean up #Hawaii’s beaches.

    "Hawaii is home to some of the world’s most beautiful landscapes. Striking blue waters, lush jungles, and pristine beaches make it a paradise. It’s also home to other unique inhabitants, such as sea turtles, dolphins, and… plastics?

    "According to a new study from the University of Hawai‘i (UH) at Mānoa, plastics are becoming the most prevalent form of pollution in the ocean, which can be detrimental to marine species and their habitat. However, researchers from UH discovered a fungus from Hawai‘i’s nearshore environment that may have the ability to break down plastics, and to top it off, they may be conditioned to do it faster. The findings were recently published in Mycologia.

    " 'Plastic in the environment today is extremely long-lived and is nearly impossible to degrade using existing technologies,' said Ronja Steinbach, lead author of the study and a marine biology undergraduate student at the UH Mānoa College of Natural Sciences, in a press release.

    "Marine fungi may be a term you’ve never heard before. This is likely due to the fact that less than 1 percent of marine fungi are known to science.

    " 'Our research highlights marine fungi as a promising and largely untapped group to investigate for new ways to recycle and remove plastic from #nature. Very few people study fungi in the ocean, and we estimated that fewer than one percent of marine fungi are currently described,' said Steinbach in the press release.

    "For this study, the research team looked at marine fungi found in #corals, #seaweed, #sand, and #sponges from Hawai’i’s nearshore. And they hope that the fungi could help degrade plastics in the marine environment.

    " 'Fungi possess a superpower for eating things that other organisms can’t digest (like #wood or #chitin), so we tested the fungi in our collection for their ability to digest plastic,' said Anthony Amend, Pacific Biosciences Research Center professor and co-lead author of the study, in a press release.

    The Hungry Fungi

    "The team exposed the fastest-growing fungi to small dishes filled with #polyurethane, a common plastic, and noted if and how fast the fungi would consume it. The team also 'experimentally evolved' the fungi to see if they would grow and consume more polyurethane the more they were exposed to the plastic.

    " 'We were shocked to find that more than 60 percent of the fungi we collected from the ocean had some ability to eat plastic and transform it into fungi,' Steinbach said in a press release. 'We were also impressed to see how quickly fungi were able to adapt. It was very exciting to see that in just three months, a relatively short amount of time, some of the fungi were able to increase their feeding rates by as much as 15 percent.'

    "The research team is currently working to see if these marine fungi can break down other forms of plastics, such as #polyethylene and #PolyethyleneTerephthalate. They’re also trying to understand how, at a molecular level, these fungi can degrade these plastics.

    " 'We hope to collaborate with #engineers, #chemists, and #oceanographers who can leverage these findings into actual solutions to clean up our beaches and oceans,' said Steinbach in a press release.

  8. Occurrence and backtracking of #microplastic mass loads including tire wear particles in northern Atlantic #air

    Few studies report the occurrence of microplastics (MP), including tire wear particles (TWP) in the marine #atmosphere, and little data is available regarding their size or sources. Here we present active air sampling devices (low- and high-volume samplers) for the evaluation of composition and MP mass loads in the marine #atmosphere. Air was sampled during a research cruise along the Norwegian coast up to Bear Island. Samples were analyzed with pyrolysis-gas chromatography-mass spectrometry, generating a mass-based data set for MP in the marine atmosphere. Here we show the ubiquity of MP, even in remote Arctic areas with concentrations up to 37.5 ng m−3. Cluster of #polyethylene terephthalate (max. 1.5 ng m−3) were universally present. TWP (max. 35 ng m−3) and cluster of #polystyrene, #polypropylene, and #polyurethane (max. 1.1 ng m−3) were also detected. Atmospheric transport and dispersion models, suggested the introduction of MP into the marine atmosphere equally from sea- and land-based emissions, transforming the ocean from a #sink into a #source for MP.
