Some Barriers to Clean Technologies

Abstract

Traditionally metallurgical industries have been using unclean technologies and the need for clean technologies cannot be over emphasised. There has always been a gap between technologies of production and those handling the environment problems arising out of production methods. The gap needs to be narrowed, and if possible eliminated by changing production technologies themselves. There are barriers to clean technologies because of a wide-ranging; technical, financial, administrative, psycho-logical etc. This article deals with some of the non-technical factors and attempts to identify approaches that may be more fruitful.
