San Diego County Composting and Chipping and Grinding Infrastructure
There are currently 12 facilities permitted for composting and six permitted for chipping and grinding in San Diego County, handling a portion of an estimated 1.5 million tons of organics disposed and used as ADC every year. Three composting facilities are permitted to accept food scraps: two fully permitted sites including the El Corazon Compost Facility in Oceanside and the Miramar Greenery in City of San Diego, and one limited pilot-scale site, the Otay Landfill Research Operation.
Even if all San Diego County facilities operated at their maximum permitted capacities (which they do not), the region would still have a capacity gap of at least 500,000 tons annually. The need for food processing capacity is even more pronounced, with only a generously estimated 40,000 tons/year of long-term capacity out of 500,000 tons being disposed. As facilities generally permit higher tonnages than they actually process, the capacity gap is even more severe than stated here. The need for composting of all sizes and technologies capable of processing a variety of feedstocks cannot be understated.
