Project Overview

Design and construction of an organic waste recycling center at the South Area Transfer Station (SATS) in Sacramento. This waste-to-energy facility will convert 25 tons of food waste per day collected by Atlas Disposal from area food processing companies, restaurants and supermarkets into renewable natural gas. This natural gas will be used to power clean-fuel fleet vehicles. The facility will be expanded, in a future phase, to process 100 tons of waste per day.
