I have often looked at the mountain our landfill has made, and thought of the billions of dollars that lay waiting there for someone to mine. A process like this, that would be able to float all the bio-waste out in a usable form is a really good first step.
There are literally billions of tons buried landfill waste, mostly plastics from the last 70 years of overpackaged, cheap, disposable trinkets and gadgets we’ve produced. All that plastic can be turned into diesel fuel using the thermal depolymerization process......
