Montauk Renewables Inc: core business model

Montauk Renewables Inc focuses on capturing landfill gas, primarily methane, and purifying it into renewable natural gas suitable for injection into pipelines or use as vehicle fuel. The company owns and operates facilities across the eastern and central US, leveraging long-term contracts with landfill owners. This model benefits from regulatory incentives like the Renewable Fuel Standard, which credits RNG production with environmental attributes sold to fuel producers.

Facilities are typically developed through joint ventures or acquisitions, with Montauk handling operations and upgrades. Revenue stems from gas sales, environmental credits, and tipping fees at wastewater plants. The business emphasizes scalability, with modular upgrades allowing expansion without major new builds.
