Engineered Compost Systems (ECS) and Athens Services in Victorville, CA, have completed a project to compost food waste and yard waste collected in the Los Angeles region. California bill SB1383 and others have required increased organic diversion, which has pulled more food waste into the composting stream. Athens tapped ECS for help with upgrading their windrow facility to increase throughput while staying in compliance with air quality and surface water regulations. The high airflow ASP maintains near-optimal process conditions to speed bio-degradation while minimizing odor generation.
