Case Study
Dairy digester cover system designed for California's regulatory environment, providing methane capture and wastewater treatment for a mid-size dairy operation.
The Challenge
Castelanelli Bros. Dairy needed a digester cover system to comply with California's increasingly stringent dairy emissions regulations. The operation required a solution that could capture methane from dairy manure lagoons while fitting within the practical constraints and economics of a family-owned dairy operation in California's competitive market.
Our Approach
EFI designed and installed a digester cover system tailored to the dairy's specific lagoon geometry and waste characteristics. The cover captures methane from anaerobic digestion of dairy manure, providing both emissions compliance and the potential for biogas utilization. The system was engineered for the practical realities of daily dairy operations, including equipment access and manure loading patterns.
Outcomes
“EFI designed a system that actually works with how we run the dairy day-to-day. They understood we're a working farm, not a lab, and the cover system reflects that practical thinking.”
