Cold-Climate Biogas & Containment Specialists
The Midwest presents unique challenges for biogas capture: harsh winters, freeze-thaw cycling, and seasonal temperature swings of 100+ degrees. EFI has developed cold-climate CLD solutions that maintain anaerobic digestion year-round, maximizing biogas production even when temperatures drop well below zero.
Wisconsin Dairy
Wisconsin is America's second-largest dairy state with over 1.2 million cows. EFI installs covered lagoon digesters for Wisconsin dairy operations ranging from 500-head family farms to 10,000+ head CAFOs. Our insulated cover technology is critical in Wisconsin's climate, where winter temperatures routinely drop below -20°F.
Minnesota Dairy & Swine
Minnesota ranks in the top five for both dairy and hog production. EFI serves the state's diverse agricultural sector with CLD systems, lagoon liners, and manure management solutions. Our JBS Worthington project demonstrates large-scale biogas capture in demanding northern climate conditions.
Iowa Swine Operations
Iowa is the nation's top hog-producing state with over 24 million hogs. Swine manure lagoons are prime candidates for covered lagoon digesters. EFI's systems capture methane, control odor, and generate carbon credit revenue for Iowa swine operations of all sizes.
Michigan Agriculture
Michigan's dairy industry continues to grow, with concentrated operations in the western and central parts of the state. EFI provides lagoon liners, covers, and biogas systems for Michigan dairy farms, food processors, and municipal wastewater operations.
Cold-Climate Innovation
Insulated Cover Technology
Standard geosynthetic covers work well in warm climates, but Midwest winters can shut down anaerobic digestion by dropping lagoon temperatures below the threshold for methane-producing bacteria. EFI's insulated cover systems solve this problem.
Insulation Layer
Closed-cell foam insulation sandwiched between geosynthetic layers maintains lagoon temperature through the harshest winters. R-values are engineered for specific climate zones.
Year-Round Production
Insulated systems maintain biogas production at 70-85% of summer peak even in January and February. Without insulation, winter production drops to 20-30% in northern climates.
Proven Performance
EFI insulated covers have operated through multiple Midwest winters with ambient temperatures below -30 degrees F. The technology is proven, not experimental.

What We Do in the Midwest
Dairy Covered Lagoon Digesters
CLD systems optimized for Midwest dairy operations. Insulated covers maintain digestion temperature through harsh winters, maximizing year-round biogas production.
Swine Lagoon Systems
Liner and cover installations for swine manure lagoons across Iowa, Minnesota, and the Midwest hog belt. Biogas capture and odor control in one system.
Insulated Cover Systems
Cold-climate cover technology with insulation layers that maintain anaerobic digestion temperature even when ambient temperatures drop below zero. Proven in Wisconsin and Minnesota winters.
Lagoon Liner Installation
HDPE and LLDPE liner systems for manure lagoons, wastewater ponds, and agricultural containment. Engineered for freeze-thaw cycling and Midwest soil conditions.
Carbon Credit Generation
Cap-and-flare systems that destroy methane and generate verified carbon credits. Zero cost to the farm operator under EFI's revenue-share model.
Food Processing Containment
Liner and digester systems for Midwest food processors including meatpacking, dairy processing, and ethanol production facilities.
Featured Project
JBS Worthington, Minnesota
EFI installed a covered lagoon digester system at JBS's Worthington, Minnesota meatpacking facility. The project captures biogas from high-strength processing wastewater in one of the most challenging climates in the US.
The insulated cover system maintains digestion temperature through Minnesota winters, producing consistent biogas year-round. The project demonstrates that cold climate is not a barrier to effective biogas capture when the system is properly engineered.
