Our Approach to
Sustainable ADC

At TIEROC, we believe better landfill operations start with smarter, cleaner solutions. Our approach is grounded in innovation, sustainability, and real-world performance—helping landfills across the Midwest maximize daily cover efficiency while reducing environmental impact and operational costs.

Purpose-Built for Landfills

Unlike traditional stone or mixed debris cover, TIEROC is made from 100% clean, nail-free wood. It’s engineered specifically to meet landfill needs—saving time, reducing equipment wear, and supporting compliance with EPA guidelines for Alternative Daily Cover (ADC).

We don’t sell “filler.” We deliver results.

Sustainability Statement

Sustainability, Built Into Every Load

TIEROC is committed to advancing circular economy practices and environmental stewardship across the waste management industry.

By repurposing clean, untreated wood that would otherwise go to waste, TIEROC helps reduce landfill reliance on mined materials like rock and stone. This not only lowers emissions associated with extraction and transport but also supports local and regional sustainability goals.

Support Businesses & the Environment with Circular Economy Recycling
TIEROC sustains a circular economy by recycling used wood materials from railroad ties, construction salvage, and more, giving these products another life as Alternative Daily Cover. And in turn, when the material reaches the end of its useful cover life, it contributes to long-term landfill gas production—supporting renewable energy capture.

Using TIEROC as a stone and gravel substitute not only saves your landfill money and time—it also reduces waste and promotes a more sustainable, closed-loop materials lifecycle.
