Heaps of pharmaceuticals, toxic chemicals found in recycled plastics (newatlas.com)

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.

And you can make PLA from something other than oil.

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.

Isnt it also found in muscles?

It can be, but that's not an easy place to get it from.

Right, I jiat remember reading that the "burning" feeling when exerting myself is from lactic acid. It would be silly to try and get enough of it from, say, making a cow work out.
