• About Us

    The Organic Materials Exchange is a project of the RCD’s of San Mateo, Santa Cruz, San Benito and Loma Prieta along with Ecology Action. In the Summer of 2006, as part of the Livestock & Land program, we conducted a manure survey in Santa Cruz, San Benito and Santa Clara Counties. The survey revealed that area residents wanted an easy way to let their neighbors know they had manure and/or compost to exchange or give away. Thus the Organic Materials Exchange was born. This site allows organics waste producers and users on the Central Coast to exchange materials. By participating in the exchange you will help extend the life of our landfills and keep pollutants out of local waterways and the Monterey Bay National Marine Sanctuary.
