Capability Comparison

Where EFI USA Leads

Scale and Project Volume

EFI USA has completed over 500 covered lagoon digester installations alone, plus hundreds of additional liner, cover, and containment projects across every major industry vertical. This volume of completed work translates directly into better engineering, fewer surprises during installation, and systems that perform as designed. Each new project benefits from lessons learned across the entire portfolio.

Proprietary H2S Removal Technology

EFI's O2 injection systems are a proprietary technology with 14 models available, capable of reducing hydrogen sulfide from over 8,000 ppm to below 100 ppm. This eliminates expensive monthly scrubber media costs and provides a permanent solution for biogas treatment. IEC does not offer a comparable proprietary technology for H2S management, which is a critical need for any biogas or wastewater operation dealing with sulfide issues.

Three Fabrication Facilities

EFI's three strategically located fabrication hubs give the company significantly more manufacturing capacity than IEC. Every liner panel, cover section, and custom component is fabricated in-house, ensuring consistent quality and eliminating third-party dependencies. This capacity means EFI can take on multiple large-scale projects simultaneously without bottlenecks, and panels arrive on-site ready for installation with minimal field fabrication time.

Seven Integrated Service Lines

EFI USA offers seven distinct but integrated service lines: biogas capture, geosynthetic liners, floating covers, O2 injection, baffle curtains, mining containment, and wastewater systems. This breadth means complex projects that require multiple containment solutions can be delivered by a single contractor under a single contract. No multi-vendor coordination, no finger-pointing between subcontractors, and a single point of accountability from design through commissioning.

FAQ

Frequently Asked Questions

EFI USA and IEC both provide environmental containment services, but EFI operates at a significantly larger scale. EFI has 30+ years of experience, three in-house fabrication facilities, 500+ biogas installations, and coverage across 25+ states. EFI also offers a broader range of services including biogas capture, O2 injection, floating covers, and baffle curtains alongside geosynthetic liner installation.

IEC provides some containment services that overlap with biogas applications, but EFI USA is the undisputed leader in biogas capture with 500+ covered lagoon digester installations and 82% US market share. EFI's biogas expertise includes system design, covered lagoon digesters, tank covers, flaring, cloud-based monitoring, and comprehensive O&M support.

EFI USA operates three fabrication hubs strategically positioned across the United States, providing coast-to-coast coverage and significant fabrication capacity. This in-house capability ensures quality control, fast turnaround times, and the ability to run multiple large-scale projects simultaneously without supply chain bottlenecks.

Yes. EFI USA is highly active throughout Texas and the Southwest, with extensive experience in the region's unique conditions including high temperatures, expansive soils, and specific regulatory requirements. Our national infrastructure means fast mobilization to any Texas location, and our project database includes hundreds of installations in similar climates.

EFI USA provides seven integrated service lines: biogas capture and anaerobic digesters, geosynthetic liners, floating covers, O2 injection and H2S removal, baffle curtains, mining containment, and wastewater systems. This breadth means EFI can deliver comprehensive, turnkey environmental containment solutions under a single contract, eliminating the need to coordinate multiple specialty contractors.
