EFI leads the US in anaerobic lagoon digester installations, with more than 500 systems. These systems produce renewable energy, capture greenhouse gases, and recover valuable outputs such as beverage-grade CO₂ from their waste.

EFI has one of the most extensive databases of biogas potential from dairy and swine manure, food-processing wastes, municipal wastewater, beverage waste, sugars, starches, crop residues, and more.

EFI’s geosynthetic liners create a reliable, waterproof barrier that protects soil and retains water. EFI has installed the most wastewater lagoon systems in the U.S., spanning industries such as municipal wastewater treatment, food production, dairy, agriculture, and chemicals.

For miners of precious metals, lithium, rare earths, salts, and carbon products, EFI liners serve as essential geosynthetic barriers that help maximize operational yields while ensuring the highest standards of environmental compliance and long-term site performance.

These durable liners provide dependable containment for leachate ponds, evaporation and crystallization ponds, and coal ash impoundments, reliably protecting surrounding soil and groundwater from contamination.

EFI’s installations protect one of our most precious resources — water. We engineer and install retention ponds, canal liners, and conveyance systems to minimize losses and evaporation, manage flows, and control water quality and environmental impact.

EFI provides engineered solutions to protect your property from erosion and related damage. We also design and implement soil stabilization systems for critical infrastructure projects, including the deepening of the Charleston Harbor shipping channel.
