Because of the range of compounds found, the researchers say that they believe recycled plastics are unfit for most uses and that they don’t contribute to a circular material lifecycle.

      Or at least use the right plastic for them. PLA readily decomposes in only a few days under industrial composting conditions at 55-70ºC. Whereas ABS, a commonly used plastic in many applications, doesn’t react to composting and can last 1000+ years in a landfill.

          You can make it from milk. PLA is polylactic acid, which is the polymerized form of lactic acid, which is in turn the product of the bacterial decomposition of lactose.
