The plasma converter can convert (almost) any waste into energy

The Prophet of Garbage

Joseph Longo's Plasma Converter turns our most vile and toxic trash into clean energy-and promises to make a relic of the landfill

How Plasma Converters Work

The intense heat from plasma torches can completely neutralize the hazardous components found in diseased livestock or contaminated soil. Engineers could transport modular, portable plasma facilities to dispose of animal carcasses or treat soil on site. Incineration of such hazardous material doesn't always destroy all the contaminates, or produces ash that is also hazardous waste. Plasma gasification would destroy or render inert any harmful material.

According to this site, the reason why this thing doesn't take off is because burying garbage has always been a lot cheaper. So unfortunate.

By the way, this thing reminds me of Mr Fusion from Back to the Future.
