Mission & History

The Garaventa family, owners, and operators of Mt. Diablo Resource Recovery have family roots going back to the 1930s when Andrea Moresco operated the one-horse and buggy rubbish collection service for the country town of Concord. Over the years, Moresco’s son-in-law, Silvio Garaventa, Sr., and his daughter, Mary Moresco Garaventa, took the small town solid waste collection operation and built an enterprise that includes multiple municipal franchises dedicated to collection, recycling, and resource recovery.

Today, Mt. Diablo Resource Recovery serves over 250,000 residents and thousands of businesses throughout Contra Costa, Napa, and Solano Counties. Mt. Diablo Resource Recovery combines excellence in customer service with competitive rates, operating recycling and recovery programs designed to increase sustainability and reduce greenhouse gas emissions.

Mt. Diablo Recycling, in Pittsburg, California, contains the area’s largest state-of-the-art recycling processing center to keep all recyclable items out of the landfill, so as much material as possible to be recycled and reused.

Our company continues to grow and change to prepare our communities for the future. Consistent with our business values, we invest in programs and technology that maximize diversion and maintain customer convenience and service.

Mt. Diablo Recycling is being transformed into the Mt. Diablo Resource Recovery Park (MDRRP), a facility that will expand our recovery efforts, increasing the diversion of material from going to the landfill.
