This contractor’s report describes the likely effects of California’s used oil management system on the virgin petroleum industry. Effects on the virgin petroleum industry are expressed in terms of changes in volumes of products produced as well as changes to energy use, emissions of carbon dioxide, and operational and freight costs for each of 20 years from 2010 to 2030. Input values for the rerefined products produced during this time period were produced by the used oil life cycle assessment conducted under contract to CalRecycle by the University of California, Santa Barbara. Please refer to the other associated reports with this project for more information.
