Should local governments prioritize the expansion of organic waste composting facilities in your area?
Republic Services has completed a significant expansion of its composting facility in Stockton, Stockton. The upgraded site, supported by a $5 million state grant, has increased its annual organic waste processing capacity to 147,000 tons.
Why it matters
This expansion directly supports California's mandate to slash organic landfill waste by 75% by 2025. By diverting this material, the facility helps reduce methane emissions while producing compost that improves soil water retention for local agriculture.
The Stockton facility grew from 1 acre to 3 acres following a $5 million grant from CalRecycle. The site is now equipped with advanced aeration systems and temperature-monitoring probes to manage decomposition.
