Client’s Requirements:
Recology Blossom Valley Organics is the largest food waste composting operation in the United States utilizing ASP. The facility is an hour outside of San Francisco in Vernalis, CA processing over 500,000 tons per year of food and yard waste from the Greater Bay Area. New regulations from the California Water Board required that Recology Blossom Valley move their existing 60-acre windrow operation onto an impermeable surface. To decrease footprint and, in turn, construction costs, Recology decided to transition their existing windrow operation to a reversing cASP system.

Client Feedback:
 “The soil is delicious! I mean just look at it! And the planter beds are so deep. We're spoiled to get to start our garden with such amazing soil. However, I have worked really hard for that compost. It's well worth it though. The soil gives me as much pleasure as the vegetables growing in it.”
