Tracking hazardous substances at industrial facilities : engineering mass balance versus materials accounting

Examines whether knowing the amounts of toxic substances entering and leaving manufacturing facilities is useful in evaluating chemical releases to the environment, waste reduction progress, and chemical management practices. In this book, tracking of these substances with engineering data is compared with a less resource-intensive alternative. 1 Front Matter 2 Executive Summary 3 1. Introduction 4 2.

Tracking of these substances with rigorous engineering data is compared with a less resource-intensive alternative to determine the feasibility and potential usefulness to the public and the government.
