In the evolving world of waste management, 2025 has ushered in a sharper focus on innovation, sustainability, and operational efficiency. From smart sensors to AI-powered fleet routing, the industry is undergoing a digital and material transformation. Two trends stand out for their impact: the rise of Alternative Daily Cover (ADC) and the rapid growth of renewable natural gas (RNG) from landfill gas.
And among ADC solutions, TIEROC is helping lead the charge—delivering operational savings today while supporting the energy recovery projects that will define tomorrow.
Trend 1: Smarter Use of Airspace with High-Performance ADC
As landfills reach capacity, every inch of airspace counts. Traditional soil cover consumes valuable volume. TIEROC, a wood-fiber ADC, is engineered to reduce that burden—offering superior coverage at a fraction of the density.
By freeing up space and streamlining operations, landfill operators can also redirect resources into high-value initiatives like RNG projects, where more captured methane translates into both environmental and economic gains.
Trend 2: Compliance-Driven Innovation
State regulations—including Illinois’ 35 Ill. Adm. Code 811.106—allow landfills to use ADC if it performs “equal to or better than” soil. In 2025, more operators are turning to approved alternatives like TIEROC that not only meet compliance standards but make inspection prep easier.
A cleaner, consistent daily cover reduces environmental risks and positions operators to meet state and federal requirements for landfill gas recovery, strengthening their case for RNG development.
Trend 3: Renewable Natural Gas (RNG) and Landfill Gas Recovery
Waste companies are doubling down on renewable natural gas (RNG) projects, transforming landfill gas (LFG) into a cleaner energy source. As WM CEO Jim Fish noted, RNG is not just a sustainability measure—it’s becoming central to the industry’s business model.
RNG powers fleets, feeds into pipelines, and reduces greenhouse gas emissions. For landfill operators, it’s a way to transform a liability into an asset. TIEROC enhances this cycle by supporting efficient landfill operations that maximize methane capture and recycling.
Trend 4: Material Simplicity, Operational Ease
No complicated slurry. No temperature-sensitive foam. No messy mixed debris. In 2025, landfill teams want ADC that’s simple, stackable, and scalable. TIEROC is delivered ready-to-use—easy to apply, easy to store, and easy to document. It’s the low-maintenance ADC that makes daily operations smoother for your crew.
Trend 5: Sustainability with a Purpose
Using a proprietary process, TIEROC is made from 100% recycled wood—clean, consistent, and landfill-safe. As ESG expectations ramp up across the waste sector, using a sustainable ADC isn’t just a smart move—it’s a reputational win. Landfills using TIEROC can proudly claim to reduce reliance on stone, soil, and contaminated byproducts while maximizing environmental performance.
Trend 6: Technology-Enabled Efficiency
AI, drones, and advanced monitoring tools are helping landfill managers predict fill rates, optimize cover use, and track compliance in real time. When paired with innovations like TIEROC’s high-performance ADC, technology ensures every cubic yard is optimized for both capacity and sustainability goals—including RNG readiness.
Ready for the Future?
The trends are clear: smarter cover strategies, cleaner compliance, and operational savings are driving landfill decisions in 2025. TIEROC sits at the intersection of these goals—helping you run leaner, cleaner, and greener.
