Liberty Tire Recycling, North America’s provider of tire recycling services, has released its 2024 Sustainability Report, highlighting another year of progress toward its vision of a more sustainable, circular economy. In 2024, Liberty collected more than 215 million end-of-life tires and reclaimed over 4.7 billion pounds of rubber—creating innovative, high-value recycled products that support infrastructure, manufacturing, and energy recovery.

The U.S. Tire Manufacturers Association (USTMA) and its member companies applaud the introduction of the Innovative Mitigation Partnerships for Asphalt and Concrete Technologies (IMPACT) Act, H.R. 1534, and its complement, IMPACT Act 2.0, H.R.2122, both introduced by U.S. Representatives Valerie Foushee (NC-04) and Max Miller (OH-07). The bills promote research and deployment of innovative pavement technologies, including rubber modified asphalt (RMA), which delivers proven economic, environmental and performance benefits.

Boral has introduced a pioneering crumbed rubber asphalt bitumen derived from off-the-road (OTR) tyres, marking am achievement in Australia. The company claims this innovative product can extend pavement life up to twice as long as conventional road treatments, offering a sustainable and high-performance solution for infrastructure.

As urban mobility continues to evolve, there is a growing emphasis on sustainable infrastructure alongside advancements in vehicle technology and energy sources. Urban roads, cycling lanes, and transport infrastructure must accommodate multiple mobility modes while addressing challenges such as traffic congestion, costs, and environmental impact.

The potential of rubberized asphalt to enhance road durability and sustainability was a key topic at the recent Workshop on Rubberized Asphalt held in Rome on December 4-5. The event, organized by ETRA and ANAS, was supported by the EU-funded RE-PLAN CITY LIFE and LIFE SILENT projects.

In 2024, Sunshine Coast Council launched a demonstration project to test the use of off-the-road (OTR) tyre-derived crumb rubber in road construction and repairs. Now, 12 months on, the results are in—and they reveal a promising future for this innovative material. The project not only confirmed that crumb rubber from OTR tyres can replace traditional crumb rubber in bitumen blends and asphalt mixes, but also provided valuable technical data on performance, constructability, and durability.

Michigan has halted the long-standing practice of burning scrap tires for energy, following a 2023 change in state law that removed tire-derived fuel from the list of renewable energy sources. The decision, coupled with the decline of biomass power plants, has left recyclers and policymakers searching for alternative ways to manage the state’s 10 million discarded tires annually.

A significant highway upgrade in Australia is set to boost road infrastructure while promoting sustainability through the use of end-of-life tyres (EOLT) in construction. The Australian government has announced a large-scale upgrade to the Bruce Highway, a major transport route connecting Brisbane to Cairns.

Launched in May 2022, the PERSEUS project focuses on creating innovative asphalt mixtures to reduce road traffic noise while incorporating recycled tire materials. The project, funded by CDTI, is led by CAMPEZO with contributions from ASFALTIA, MOEVE, and SIGNUS, and support from TECNALIA.
