Santa Ana Climate Action Plan <br />Solid Waste, Water and Wastewater Measures <br />Food waste can be broken down in an anaerobic digester to <br />produce renewable energy. The state mandate under AB 341 <br />requires an increase in the rate of recovery of commercial <br />waste for recycling, and some of this increased recovery will <br />likely be food waste. Initially, this waste may be composted, <br />but through this measure the City will arrange for it to be sent <br />to a digestion facility to allow energy recovery. <br />Type of Measure <br />Voluntary <br />. ...........
