Some Barriers to Clean Technologies

摘要

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 environmental problems arising out of the 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 factors: technical, financial, administrative, psychological etc. This article deals with some of the nontechnical factors and attempts to identify approaches that may be more fruitful.
