This is how we reduce our landfills and convert it all from useless toxins to useful raw material 👌 just gotta train some shrooms on it!

I wish it were that easy. A big problem is that it's very hard to get microbes to do just the one thing you want to achieve in complex environments, especially recalcitrant environments like landfills. There's 40 years or so of scientific literature on exactly this subject and there's been quite a lot of progress but still no magic pill. The reality is that our junk is just going to long outlast us.
Microbes essentially have the genetic complement to do the job but there's lots going on that determines what, when, where and how they eat. Sometimes the bad stuff gets broken into food or building blocks, but then sometimes digesting something toxic ends up being conjugated into something equally toxic with a longer half-life.
Would it at least be possible that it's a good way to kick start plastic recycling. What we call recycling now is an absolute joke. The only things right now that are actually recyclable are metals.
