AbstractSeveral coordinated hazardous waste minimization projects have been undertaken at our facilities involved in III-V device manufacturing. These include modifications to existing processes to reduce or eliminate emissions of CFCs, 1,1,1-TCA, xylenes, ethylene glycol ethers, 1,2,4-trichlorobenzene (in photoresist stripper), and other compounds. These issues are addressed in turn, noting the unique aspects of GaAs and GaP device manufacture that need to be taken into account. Goals achieved have been complete cessation of CFC and 1,1,1-TCA use and 33% reductions in xylene and 1,2,4-trichlorobenzene usage since 1990, despite significant increases in total production volume during the same time period. Specific strategies are also described for tracking chemical use and sharing best practices for hazardous waste reduction across functional groups.

This paper presents an evaluation of the status and direction of toxic/hazardous waste reduction in the chemical and petrochemical industries from an international perspective. Pertinent approaches, experiences and trends are described. Industrial waste management has evolved from an “end-of-pipe” treatment mentality to source reduction as the preferred option. It is generally agreed that the Chemical/Petrochemical Industries generate more hazardous and toxic waste than any other industrial sector. Also because of the large quantities of materials and energy used by these industries, significant opportunities are available for waste reduction. In almost all cases costs savings have resulted, many of which are significant. The importance of pollution prevention by “clean technologies” instead of remediation, multi-media considerations and the significance of product life-cycle assessment in pollution prevention programs is stressed. Examples are provided which demonstrate, that a proactive approach by DOW, E.I. DuPONT, AMOCO, 3M Corp., CIBA-GEIGY and others is now becoming the norm. From an international policy perspective, important commonalities and differences in strategy and efforts for toxics/hazardous waste management exist. Much can be learned by the mistakes and solutions between cultures and countries. Much progress has been made in protection of public health and the environment - but much remains to be done. This paper is intended to provide a stimulus for discussion aimed at optimizing future waste minimization activities in the chemical and petrochemical industries.

The objective of this paper is to present information on pollution prevention practices and economics to recommend it as a significant part of industrial waste management. The waste reduction/waste minimization/pollution prevention sequence is described and optimized. Experiences in pollution prevention for three separate industries are presented. The pollution prevention approach is stressed for its positive effects on cost, expenses, environmental benefits, as well as other less tangible benefits. The conclusion is that you can generally reduce, minimize or eliminate waste and make money doing it. This is especially the case with old processes having significant residuals.

Waste minimization/pollution prevention has become the strategic approach to waste management in the 90s and the hope for environmental management as we enter the third millenium. Nearly a decade ago, EPA's Office of Research and Development began a focused Waste Minimization Research Program to identify and demonstrate technology for reducing the generation of wastes and shifted the Agency's priority from end-of-pipe controls to the prevention of waste generation. The purpose of this presentation is to share a number of the results from several years of researching engineering solutions to multi-media problems, building a sound scientific foundation to support pollution prevention (P2) principles, and developing and demonstrating pollution prevention technologies, tools, and techniques. The “tools of the trade” for pollution prevention are the research reports that provide results of technology development, the case studies and demonstrations of P2 technologies, and the technical guides and manuals for conducting P2 activities. Technology Development - Tools resulting from technology development include the numerous research reports and briefs from: 1) the Life Cycle Assessment (LCA) Program, 2) Pollution Prevention Measurement Projects, and 3) the Innovative Clean Technologies Program. Technology Demonstration - Tools resulting from technology demonstration include the research reports and summaries from: 1) the Waste Reduction Innovative Technology Evaluation (WRITE) Program, 2) the Waste Reduction Evaluation At Federal Sites (WREAFS) Program, 3) the New Jersey/EPA Waste Minimization Assessment Project, and 4) Small Generator Waste Minimization Assessment Program. Technical Guides and Manuals - These tools include: 1) Facility Pollution Prevention Guide. 2) 16 industry specific guides to pollution prevention, 3) Background Document on Clean Products Research and Implementation, and 4) Industrial Pollution Prevention Opportunities for the 1990s. Much of the EPA's Pollution Prevention RD&D Program has focused on the development and demonstration of practical tools to encourage the development and adoption of processing technologies mid products that will lead to reducing the aggregate generation rates for pollutants entering various environmental media. The strategic direction for pollution prevention RD&D through the 1990s is: 1) to study high risk environmental problems where P2 offers a cost-effective solution for reducing the risks, 2) to conduct cross-cutting research such as measurement, modelling, and LCA that can be applied to multiple problems, and 3) to establish joint global P2 RD&D ventures where products and processes know no waste generating boundaries.
