Processing Facilities Tour

What do 4,000 tons of organics, recycling, and garbage look like and how does it get processed in one day?  If you are a Castro Valley Sanitary District (CVSan) resident or business owner, find out for yourself and see what happens to your recycling, organics, and garbage once it leaves the curb. The Processing Facilities Tour takes attendees to the Alameda County Industries (ACI) Materials Recovery Facility, where CVSan’s recyclables are processed, and to the Davis Street Transfer Station, where CVSan’s garbage goes before heading to the landfill.

Davis Street processes 4,000 tons of materials a day with four, state of the art processing facilities, including:
  1. A Leadership in Energy and Environmental Design (LEED) Gold certified organics building.
  2. A single stream materials recovery facility (MRF) that houses a high-tech optical sorter that uses infrared light and manual sorters that separate materials with precision and speed. 
  3. A construction and demolition debris MRF (materials from construction and large remodeling jobs).
  4. A $10 million Expanded Construction & Demolition/Commercial Materials Recycling Facility.
