CalMAX: California Materials Exchange

CalRecycle's materials exchange portal helps connect businesses, organizations, manufacturers, schools, and individuals with the most effective online resources for exchanging materials. One business' trash is another business' treasure. By reusing materials, we conserve energy, resources, and landfill space, while reducing disposal, green house gas emissions, and purchasing costs. CalRecycle no longer lists individual materials available for exchange because the links below provide better online options. Please use one or more of the following resources to list or find materials. Thank you for your continuing commitment to reuse!


Material Exchange Resources


To locate additional resources or if you are looking for an exchange that's not listed on the CalMAX portal, popular search engines (Bing, Google, Yahoo!) may help you find it by using keywords: "materials exchanges" or "reuse."

Suggestions: CalRecycle welcomes your feedback on resources to list and find materials. If you know of other effective reuse tools that should be added to this list, please submit them.
