Understanding technology: new concepts for air classification in waste processing and resource recovery

Abstract

It is noted that mechanical separation of municipal solid waste for resource recovery or waste-to-energy production, while viewed with great optimism in the early 1970s, has failed to receive widespread application in the 1990s. Using mechanical separation as a focus, it has been possible at Duke University to educate engineers to be more effective in addressing solid waste management problems in particular and problems in science, engineering, and technology in general.<>
