Briefing on Food Waste Recycling to Peninsula Breakfast Club
Briefing on Food Waste Recycling to Peninsula Breakfast Club The Peninsula Breakfast Club received an overview on the Sanitation Districts' food waste recycling program. Club members, who are mostly former military officers and aerospace engineers, saw how food waste is received at the Puente Hills Materials Recovery Facility in Whittier, processed into a slurry, and then trucked to the Joint Water Pollution Control Plant in Carson to co-digest with the solids removed from the wastewater treatment process. Food waste is ultimately converted to compost and to biogas that is used to produce green power.
