  1. Briefing Paper on Industrial Ecology and EPA

    Allen, Derry
    Industrial Ecology (IE) is a systems approach to efficient resource use and protection of the environment. Instead of just devising improved methods of waste treatment and disposal, we look for the best opportunities to reduce waste throughout the total material cycle from virgin materials to finished products to end of product life. Instead of controlling industrial pollutants from different sources one by one at different times and with different technologies, we try to look across whole facilities, regions and even whole industries and make changes wherever in the system it is most effective to do so. Many thoughtful observers in the research and private and public...

  2. The Program on Science, Technology and Environmental Policy: A Research Agenda for the Next Generation of Environmental Regulation

    Foster, James Lloyd; Larson, Harold; McCulloch, Lewis
    In the view of many industry representatives there already exist technologies with improved environmental attributes for which it has not been possible to get regulatory approval or even concerted regulatory review. Is technology now “getting well ahead” of regulation? Can the regulatory approval process for new technologies keep up with the opportunities for innovation? There is a clear need for an objective, credible institutional base for evaluating technologies that are needed to address contemporary and long-term environmental problems. The Program in Science Technology and Environmental Policy (PSTEP) being launched at MIT seeks to be an important part of that institutional base. If the manufacturer’s claims can be verified,...

  4. New Opportunities for Metals Extraction and Waste Treatment by Electrochemical Processing in Molten Salts

    Sadoway, Donald R.
    Molten salt electrolysis is a proven technology for the extraction of metals -- all the world's primary aluminum is produced in this manner. The unique properties of molten salts also make them excellent media in which to treat a variety of forms of waste. Of special note in this regard is electrolysis in molten oxides, a concept put forward by the author, initially as a "clean technology" for producing primary metal. However, in the context of waste treatment, electrolysis in molten oxides is a process offering the prospect of changing the valence of dissolved heavy metals while making pure oxygen gas as...
