…superheating landfill waste using an electricity-conducting gas called plasma, which rearranges the waste’s molecular structure into a synthetic gas. The end product can be converted into transportation fuels such as diesel or ethanol, industrial products like hydrogen and methanol, or used as a natural gas substitute to fuel electric plants.
The question is: How much quantity at what cost? I also wonder if this becomes economically viable, how it would change the value of waste in the long run?
