Toxics Use and Hazardous Waste Reduction Clearinghouse

By reducing your chemicals and hazardous wastes you can potentially save money, lessen your environmental liability and deal with fewer regulations.

Welcome to Oregon DEQ’s TUHWR Clearinghouse, the state’s first-ever Web-based, searchable database for toxics use reduction and hazardous waste reduction success stories. For more than 20 years, DEQ has worked with Oregon businesses to reduce toxic chemicals and hazardous wastes. Using pollution prevention principles, DEQ’s TUHWR Program assists businesses, including encouraging companies to consider using fewer toxic chemicals, reconsider processes and practices, and examine ways to use the same materials repeatedly in existing processes.
