Zero Cost Methane Destruction

Cap-and-Flare Program

Q: What does it cost me?

Nothing. EFI covers all installation, equipment, and ongoing maintenance costs. There is zero upfront cost to the farmer.

Q: Does it affect my operations?

No. The cover sits on the lagoon. Your waste management process stays the same. EFI handles all equipment installation and ongoing maintenance.

Q: When do I start getting paid?

Revenue sharing begins after EFI recoups 2x its investment (typically 2-3 years), then a 50/50 split of carbon credit revenue for the duration of the agreement.

Q: How long is the agreement?

Typically 15-20 year agreements with clear terms. Equipment is maintained by EFI throughout the entire contract period.

Q: Is this like RNG/biogas?

Simpler and more accessible. No gas upgrading or pipeline interconnection needed. We destroy methane on-site via an enclosed flare and earn carbon credits instead. Capital cost is $300K-$1.5M vs. $10-50M+ for RNG.

Q: What about the smell?

The HDPE cover dramatically reduces lagoon odor. Most farmers see significant improvement in neighbor relations after installation.

We install HDPE covers and enclosed flares on your lagoon at zero cost. Destroy 98% of methane emissions. Earn carbon credits. Share the revenue.

How It Works

Four Steps to Revenue from Methane

We Install

HDPE cover + enclosed flare on your lagoon — at zero cost to you.

We Operate

EFI handles all maintenance, monitoring, and equipment upkeep.

Destroy 98%

Methane captured under the cover and destroyed via enclosed flare at 99.5% efficiency.

You Get Paid

Carbon credits sold on verified markets. Revenue shared 50/50 after 2x MOIC.

Beyond Revenue

Additional Benefits for Your Operation

Odor Reduction

HDPE cover dramatically reduces lagoon odor — better neighbor relations and community goodwill.

Regulatory Compliance

Stay ahead of tightening EPA methane rules and state regulations before they become mandatory.

Sustainability Credentials

Verified carbon credits demonstrate real, measurable climate action to buyers and supply chain partners.

Community Relations

Proactive environmental stewardship builds goodwill with local communities and regulatory bodies.

The Smarter Path

Cap-and-Flare vs. RNG

RNG projects require massive scale, pipeline access, and years to pay back. Cap-and-flare makes methane destruction accessible to the other 17,500 sites.

Metric	Cap-and-Flare	RNG
Capital Cost	$300K – $1.5M	$10 – $50M+
Minimum Viable Scale	500+ head dairy	5,000+ head dairy
Revenue Model	Carbon credits + 45Q	LCFS + RINs + 45Z
Policy Risk	Low (diversified buyers)	High (CARB 2040 sunset)
Infrastructure	None (on-site)	Pipeline interconnection
Payback Period	1 – 4 years	10 – 20+ years

The Opportunity

45 Million Metric Tons of CO₂e — Addressable Today

Approximately 17,500 agricultural and municipal sources emit an estimated 45 million metric tons of CO₂e annually from uncaptured methane. These sources are too small for RNG but represent a significant, addressable emissions reduction opportunity.

Source Type	Candidate Sites	Est. CO₂e
Dairy Farms (500+ head)	~5,000	~18 MMT/yr
Swine Operations (2,000+ head)	~2,500	~9 MMT/yr
Wastewater Treatment Plants (<5 MGD)	~10,000	~18 MMT/yr
Total	~17,500	~45 MMT/yr
