The Zero Waste Network is a project of the University of Texas at Arlington's Enviornmental Training institute. The tools on this site are presented free of charge to help you find pollution prevention alternatives that work for your facility. They were originally developed throught the support of grant funding from the United States Environmental Protection Agency and contributions from several state, private and non-governmental entities. If you need assistance implementing these options contact us, or enroll in one of our upcoming classes .
