This publication looks at the twelve industrial sectors responsible for the production of these hazardous wastes. This catalogue highlights examples of successful hazardous waste reduction and recycling projects undertaken by individual companies in a variety of industries. It is based on a review by Pollution Probe of the trade and environmental literature from the past ten years, with an emphasis on recent publications. The intention of the catalogue is to provide companies with useful information on practical, cost-effective reduction and recycling techniques being used by their counterparts in Canada, the United States and abroad. The cases featured in this catalogue were drawn from a wide range of sources and represent the best of hundreds of examples from the literature that were considered.
