Case Study
Pacific Rim Dairy | California
Three-lagoon, two-stage digestion system at Pacific Rim Dairy in California, repurposing existing ponds with HDPE covers and air injection.
Historical project details checked against the original EFI case history on September 16, 2026. Reported equipment and operating results describe that project period.
The Challenge
Problem
Pacific Rim Dairy sought to use three existing manure lagoons for anaerobic digestion. Maas Energy Works developed the project, with process design by Dr. Hector Cumba and civil design by 4-Creeks Inc.
Our Approach
Solution
The 2014 case history describes a two-stage process across three lagoons. EFI installed baffle and mixing systems, HDPE covers and air injection for biogas conditioning.
