The US scrap tire market has transformed over three decades from a chronic disposal problem into a managed recycling sector, but it is not static. Generation volumes, recovery method mix, market prices, and regulatory frameworks all shift over time. Operators who understand the trend direction in each of these dimensions make better decisions about equipment investment, business model design, and market positioning than those reacting to the present without anticipating what comes next.
This article covers the current state of the US scrap tire market across five dimensions: generation volumes and the factors that drive them, recovery method trends and how the mix is shifting, price trends in key output markets, regulatory direction at federal and state levels, and the emerging forces, electric vehicles, advanced pyrolysis, and circular economy policy, that will shape the market over the coming decade.
US scrap tire generation has been broadly stable at 280 to 300 million tires annually for the past decade, reflecting the relatively stable US vehicle fleet size and average tire replacement frequency. The vehicle registration base of approximately 290 million registered vehicles, each replacing tires on average every three to four years, produces a predictable annual generation volume that does not change dramatically year to year absent major structural shifts in the vehicle fleet.
Two structural shifts are underway that will affect generation volumes over time. Electric vehicle adoption affects tire wear rates: EVs are significantly heavier than equivalent ICE vehicles due to battery weight, and the high torque of electric motors accelerates drive tire wear. Early data from markets with high EV penetration suggests EV tires wear 20 to 30% faster than comparable ICE vehicle tires. If EV adoption in the US reaches the projections in current federal clean vehicle programs, per-vehicle tire consumption could increase, potentially adding 10 to 20 million tires annually to the generation base by the early 2030s.
TDF combustion has been the dominant recovery method for US scrap tires for the past three decades and remains the largest category today at approximately 40 to 45% of total beneficial use. However, its share is declining relative to ground rubber and other value-added applications, as cement kiln TDF capacity reaches effective ceiling levels and other markets grow.
Ground rubber (crumb rubber) has grown from a niche application to a mainstream market, driven primarily by synthetic turf installation and asphalt rubber programs. California’s crumb rubber asphalt program, which specifies recycled tire rubber in highway resurfacing projects, has consumed significant volumes of crumb rubber annually and provided a policy-supported floor for crumb rubber demand in that state. Other states with similar mandates or programs contribute to the trend.
Civil engineering applications, while a smaller percentage of total use, are growing in technical acceptance as the body of documentation from US and international project experience accumulates. The FHWA’s technical guidance, state DOT approved materials programs, and growing familiarity among geotechnical engineers with tire bale properties are all driving incremental adoption.
For US tire recyclers positioning for the civil engineering market, producing bales to the international PAS 108 standard provides the specification documentation that civil engineering buyers require. The Gradeall MKII Tire Baler is designed to produce bales to this specification, and Gradeall’s export case studies document the international civil engineering applications that provide technical precedent for US project specifications.
TDF bale prices correlate with energy commodity markets, primarily coal and natural gas. The coal price increase in 2021 to 2022 improved TDF bale values; the subsequent moderation in coal prices has reduced the price premium for TDF relative to the long-run average. Natural gas price volatility affects TDF demand at industrial boilers and some cement kilns that can switch between fuels. TDF bale prices over a 10-year horizon have averaged $25 to $40 per bale, with cyclical variation around this mean.
Crumb rubber prices have been more stable than TDF, supported by synthetic turf and molded product demand that is less correlated with energy commodity cycles. The synthetic turf market has grown steadily with school and municipal athletic facility investment. Asphalt rubber demand is policy-driven and varies by state program funding levels. Crumb rubber at 10 to 20 mesh has typically commanded $200 to $400 per ton at US processors, compared to $60 to $100 per ton equivalent for TDF bale material.
Federal regulatory direction under the EPA continues to support tire recycling through RCRA implementation guidance, TDF combustion permitting, and research programs on crumb rubber safety. The EPA’s 2019 Federal Research Action Plan on Recycled Tire Crumb has been influential in providing evidence for regulatory decisions on synthetic turf applications.
State regulatory programs continue to evolve toward stricter storage standards, tighter permit conditions, and, in some states, expanded generator obligations that increase the regulated demand for legitimate tire collection services. States that have not yet implemented comprehensive tire management programs are under increasing pressure from illegal dump cleanup costs to develop them. The regulatory direction at state level is toward tighter management, which creates better market conditions for licensed processors.
“The regulatory trend is consistently in the direction of more structured tire management, not less,” says Conor Murphy, Director of Gradeall International. “Every state that tightens storage standards, expands generator obligations, or funds collection infrastructure is creating better conditions for licensed processors. The market improves for compliant operators as the regulatory floor rises.”
Pyrolysis of scrap tires is moving from demonstration scale toward commercial reality in the United States. Several companies are operating or building commercial-scale pyrolysis facilities that produce pyrolysis oil, recovered carbon black, and steel wire from scrap tires. The quality of pyrolysis oil and carbon black from tire feedstock has improved significantly with technology development, and the economics are increasingly viable at current oil prices. If pyrolysis scales to represent 10 to 15% of US tire management, it changes the competitive landscape for TDF buyers and creates a new high-value outlet for tire feedstock.
For operators building toward any processing future, the collection, sidewall cutting, and baling infrastructure from Gradeall provides the upstream processing capability that feeds both current markets (TDF, civil engineering, export) and emerging pathways (pyrolysis feedstock, advanced material recycling). The Gradeall tyre recycling equipment range covers the full pre-processing spectrum from OTR tire cutting through to standard passenger tire baling, serving operations at any position in the processing chain.
Generation volumes are expected to be broadly stable in the near term and potentially grow modestly over the medium term as EV adoption increases per-vehicle tire wear rates. The combination of a growing vehicle fleet and higher tire consumption per EV compared to ICE vehicles is a net positive for scrap tire generation volumes, which is favorable for the recycling sector. No significant technology is expected to dramatically reduce tire wear rates in the near term.
EV tires, particularly in the current generation, are physically similar to ICE vehicle tires in composition, dimensions, and construction. They process through standard tire recycling equipment without modification. The primary difference is wear rate, meaning EV tires enter the waste stream sooner than comparable ICE tires. Future EV tire designs that incorporate novel materials for rolling resistance optimization could create new processing considerations, but these are speculative at this stage. Current EV tires are processed identically to standard passenger tires.
The synthetic turf crumb rubber market has faced some headwinds from regulatory scrutiny of crumb rubber safety in turf applications, particularly for children’s playing surfaces. Some municipalities have specified alternative infill materials for new turf installations as a precautionary measure. At the same time, the turf market continues to grow as school and municipal athletic facilities replace natural grass. The net trend is stable to modest growth in crumb rubber demand for turf, with quality and safety documentation becoming more important for supplier qualification.
No reversal of state tire landfill bans is expected. Tire landfill bans are deeply embedded in state solid waste policy and have been in place long enough that the landfill disposal infrastructure no longer exists in most states to handle significant tire volumes. The political and regulatory direction is toward maintaining and in some cases tightening tire management requirements, not relaxing them. The landfill ban is effectively permanent from an operational planning perspective.
US tire recyclers should monitor commercial-scale pyrolysis facility development in their region and consider whether pyrolysis operators in their area will become tire feedstock buyers. Pyrolysis operators typically prefer shredded tire chips rather than whole tire bales, which means a recycler with shredding capability is better positioned as a pyrolysis feedstock supplier than a baling-only operation. Maintaining flexibility in processing capability, producing bales for current markets while developing shredding capability for future markets, is the practical positioning approach for operations anticipating pyrolysis market development.
