In a potentially encouraging sign for reducing environmental waste, researchers have discovered microbes from the Alps and the Arctic that can break down plastic without requiring high temperatures. Although this is only a preliminary finding, a more efficient and effective breakdown of industrial plastic waste in landfills would give scientists a new tool for trying to reduce its ecological damage.Scientists from the Swiss Federal Institute WSL published their findings this week in Frontiers in Microbiology, detailing how cold-adapted bacteria and fungus from polar regions and the Swiss Alps digested most of the plastics they tested — while only needing low to average temperatures. That last part is critical because plastic-eating microorganisms tend to need impractically high temperatures to work their magic. “Several microorganisms that can do this have already been found, but when their enzymes that make this possible are applied at an industrial scale, they typically only work at temperatures
