TIEROC ADC acts as a secondary producer of biogas – better than soil and rock
Hampshire, Illinois (November 11, 2025) – Landfills across the Midwest are adopting TIEROC, an engineered alternative daily cover (ADC) made from clean, recycled wood, to boost renewable natural gas (RNG) production and create new revenue streams. This shift aligns with the national trend of increasing landfill gas capture, with RNG production from landfill gas rising from 19% to 40% since 2020, according to the American Biogas Council.1
TIEROC serves as a high-performance ADC that not only ensures regulatory compliance but also acts as a secondary producer of biogas, offering a superior alternative to traditional soil and rock covers. By preserving landfill airspace, enhancing methane capture, and producing fuel with high energy value, TIEROC transforms daily operations into long-term energy and revenue growth opportunities.
“As landfills across the Midwest look for ways to remain compliant while expanding revenue opportunities, TIEROC is proving to be more than a cover solution, it’s a revenue catalyst,” said Greg Kutschke, Executive Vice President of TiEnergy. “By preserving airspace, enabling methane capture, and fueling RNG production, TIEROC helps operators turn compliance into profitability.”
With RNG investment accelerating nationwide, TIEROC is positioned as the go-to ADC for operators in the Midwest seeking compliance, performance, and new energy revenue growth.
Key Benefits of TIEROC ADC
- Optimized RNG Performance: Consistent use of TIEROC enhances methane generation and supports steady RNG capture, giving operators more predictable energy yields and revenue growth. With RNG production from landfill gas doubling from 19% to 40% since 2020, operators are increasingly prioritizing technologies that support consistent biogas output.1
- Circular Economy Impact: Recycled railroad ties → Clean wood → ADC → Methane capture → RNG → Renewable power. A closed-loop system that reduces landfill volume and produces renewable energy.2
- Improved Economics: Reduces volume consumed by cover material, extending landfill capacity and maximizing profitability. Landfill biogas investment has exceeded $1 billion annually for two straight years, proof that capacity preservation and gas capture translate into real market opportunity.3
- Weather-Resistant Performance: Unlike dirt, soil, or rock, TIEROC applies cleanly in all conditions, avoiding the muddy mess that slows operations after rain or snow and keeping equipment and crews moving.
- Compliance-Ready: Designed for inspector approval, TIEROC applies cleanly and consistently, simplifying daily compliance and reducing the risk of costly delays.
“The future leaders in waste management will be the landfills that move beyond traditional cover methods and embrace RNG as a strategic asset,” said Steven Berglund, President of Midwest Companies. “TIEROC ADC helps operators capture more value from every ton of waste, fueling both profitability and sustainability.”
