No Garbage

Some ideas help too much so they are bought by those that would lose money it was ever used on a massive scale. Its happens more often than not with green technology . A few years ago I watched a TV program about a guy who invented  a waste disposal unit that would incinerate garbage and reduce it to its base elements and store it for other uses. the only by product was a small chunk of what resembled onyx or black glass. I don't know whatever happened to his invention or him . Just the idea could have drastically helped our world.
