The U.S. Environmental Protection Agency (EPA) has joined with industry, States, and local regulatory agencies, as well as pollution prevention experts, to implement the EPA's Industrial Pollution Prevention Project (IP3). The IP3 is an agency-wide, multimedia project focusing on industrial pollution prevention. The objectives of the IP3 are twofold: (1) to incorporate pollution prevention into the industrial effluent guidelines process, and (2) to extend information to industries and to the consuming public to better establish and spread the pollution prevention ethic. The IP3 includes 13 tasks, one of which is to gather together all readily available information on the pollution prevention measures implemented by industries in other countries, to put all that information into electronic files so that it is accessible to all interested parties, and to compile all the case studies into a hard-copy compendium. This compendium has been prepared by the IP3 to provide EPA, States, industries, and other interested parties with access to non-U.S. pollution prevention case studies. The compendium includes many countries' experiences related to a variety of pollution prevention concepts and technologies.
