Contra Costa Waste (RCTS) diverts up to 91% of the material it receives. We recycle and recover tires, metals, mattresses, propane tanks, appliances, carpet, yard waste and construction and demolition.

Yard Waste We Recycle

All yard waste is ground, transported and then converted into soil enriching compost.
All scrap metal is pulled out, sorted and recycled, keeping landfill waste to a minimum.
