A recent guest on our nationally syndicated Motley Fool Money radio show was David Wolman, author of the new book The End of Money: Counterfeiters, Preachers, Techies, Dreamers -- and the Coming Cashless Society. Wolman recently wrote an article about the plasma gasification of municipal solid waste. In this audio segment, he discusses what "plasma gasification" is and how Waste Management is investing in this technology that could revolutionize the trash industry.
