TDF vs. Coal Benefits at a Glance
More Heat, Less Cost, Lower Impact—The Smarter Fuel Choice for Cement Production
Lower Fuel Cost
As of August 2025, In North America , TDF lands at ~$0.5–$1.9/MMBtu, while current U.S. coal benchmarks sit around $2.5–$3.4/MMBtu—a 30–70%+ fuel-cost advantage for TDF depending on local incentives & delivered pricing.

Higher Energy Efficiency
TDF delivers ~26–30 MMBtu/ton, about 25% higher than typical U.S. coal (~20–24 MMBtu/ton), enabling hotter, more efficient kiln combustion and reduced fuel volume requirements—translating to improved throughput & lower overall fuel costs.

Environmental Advantages
TDF’s higher BTU value promote more complete combustion at optimized flame temperatures, suppressing thermal NOx formation compared to many U.S. coals. The reduced nitrogen content in tire rubber further limits fuel-NOx generation.

Frequently Asked Questions
Got questions? We have answers!
Is TDF safe and compliant?
Yes. U.S. EPA studies show that properly fired TDF meets or exceeds cement kiln emission standards, often reducing NOₓ by 20–50% compared to many U.S. coals. Metal content from the tire’s steel belts is chemically bound into the clinker, eliminating disposal and contributing beneficial 1–2% Fe₂O₃ to raw mix chemistry.
What’s the return on investment?
Plants often realize ROI in 6–12 months. With delivered TDF at $0.50–$1.90/MMBtu vs. coal at $2.50–$3.40/MMBtu, cost savings can exceed $1 million annually for a kiln replacing 20–30% of its coal with TDF. Additional upside comes from reduced urea/NOₓ control costs and avoided landfill tipping fees.
Can my kiln run TDF without major changes?
In most retrofit scenarios, only minor adjustments to fuel feeding and handling are required. CM works with kiln operators to achieve uniform 2" minus sizing, consistent moisture (<2%), and stable BTU values (26–30 MMBtu/ton)—ensuring predictable combustion profiles without compromising production rates.
Does TDF affect kiln performance & clinker quality?
TDF’s higher volatile content promotes more complete combustion, while its ~25% higher energy density vs. coal supports stable flame temperatures and clinker mineralogy. For steel-in TDF, the added iron can partially replace purchased iron ore or mill scale, lowering raw material costs and tightening chemical control without increasing build-ups when chip size and cleanliness are maintained.
