POLLUTION PREVENTION TECHNOLOGIES - A REVIEW AND CLASSIFICATION

Waste minimization practices, reported in the literature for major ind ustries using or generating hazardous materials, were reviewed. Techno logies are summarized briefly in this paper. The information was reorg anized according to the function served by the material industrially, and the general chemical nature of the material. Ten basic functions w ere identified, as binding, pigmentation, reactants, reaction inhibiti on, catalysis, bleaching, mass deposition, mass removal, by-products, and end-products. The resulting perspective of this review is general with respect to industry, and with respect to waste phase, and conside rs productivity benefits along with prevention of risks associated wit h pollution. Similarities in waste reduction opportunities are evident between processes where hazardous materials perform similar functions , suggesting general approaches to industrial hazardous waste reductio n.
