Continental has acquired a patent portfolio and launched a pilot facility for the production of pyrolysis oil. The investment lays the foundation for recycling complex rubber compounds on an industrial scale. The patented pyrolysis technology solution employed by ContiTech aims to recover high-quality raw materials from waste rubber and systematically replace fossil resources.

Pyrolysis is based on a thermal process. Through controlled heating in a low-oxygen environment, the waste rubber is thermally broken down into its basic components. This produces a gaseous energy source, recovered carbon black and a high-quality oil that is similar in composition to fossil crude oil.

Ecolomondo has received a repeat order and shipped its second commercial truckload of 23 metric tons of recovered carbon black produced at its Hawkesbury TDP facility to its main offtake client.

The Canadian cleantech company’s main offtake client recently approved the quality of the rCB produced at the Hawkesbury TDP facility after testing all quality thresholds, including humidity, pellet size, pellet hardness, particle size, as well as ash and fines content. Ecolomondo says it is also expecting to receive quality approval from another offtake client.

The main offtake client placed an initial order for one truckload (23 metric tons) and has subsequently placed a repeat order for another truckload, which has also been shipped.

Carbios has signed a multi-year commercial agreement with Indorama Ventures. The agreement covers the supply of biorecycled monomers from its Longlaville plant, which will be transformed into r-PET filaments by Indorama Ventures and then integrated by Michelin into the manufacturing of its tires.

Using its enzymatic PET recycling technology, Carbios will produce monomers from complex PET waste at its future industrial site in Longlaville. Indorama Ventures will handle the repolymerization and production of technical filaments. Michelin will use these innovative materials in its tire reinforcements.

“This commercial agreement with Indorama Ventures marks a new step in the realization of our industrial project.

The share of renewable and recycled materials in Continental’s tire production averaged 26% in 2024, a figure that the tire manufacturer aims to increase by 2-3% in 2025. By 2030, Continental’s target is to use over 40% of renewable and recycled materials.

As carbon black and silica make up a large proportion of the raw materials in tire production, Conti aims to increase the sustainability of these fillers to help hit its materials target.

Silica: Rice husks

Continental is increasingly using silica variants across its whole tire portfolio in order to reduce resource consumption while still meeting required safety, efficiency and rolling resistance requirements.

Modern Meadow has entered a development partnership with Mercedes-Benz that leverages Modern Meadow’s Innovera material to develop a bio-design leather alternative combining chemically recycled AMG GT3 racing car tires, plant-based proteins and biopolymers for the Concept AMG GT XX technology program.

The development partnership aims to further develop this innovative material for series production and set new standards in vehicle interiors. Made of Innovera, the leather alternative

The recycling process is conducted in accordance with the mass balance approach. Because it replicates key properties of the collagens found in leather, the material offers a level of design freedom equivalent to that of traditional leather and can be produced with different finishes such as nubuck, full grain or suede and in various colors and haptics.

Prism Worldwide has announced a trio of advancements, in odor reduction, sustainable thermoplastic vulcanizates (TPV) development and high-content ethylene propylene diene monomer (EPDM) reuse. These three challenges have been considered as barriers to wider adoption of recycled materials in consumer and industrial products.

“This is a turning point for end-of-life tire recycling and sustainable polymer development,” said Bob Abramowitz, CEO, Prism Worldwide. “These are not incremental improvements. We’ve tackled odor, cost and performance, three of the biggest barriers to more widespread adoption of recycled materials, and overcome them all with commercially viable solutions.

“Our team’s diligence in developing solutions that solve these challenges allows us to deliver cost-effective, high-performance materials without requiring customers to pay a green premium.

Bridgestone Corporation will provide the 2025 Bridgestone World Solar Challenge (BWSC) with new Enliten technology tires featuring the first application of recycled materials developed through co-creation with partners that increase the ratio of recycled and renewable materials to over 65%. The company will supply the tires to 33 teams from 17 locations.

The BWSC, which will take place August 24-31, challenges participants to traverse approximately 3,000km across the Australian continent using only limited solar power.

Bridgestone will supply tires with Enliten technology, which helps deliver the performance required for solar cars and advance sustainability. For the first time, Bridgestone has applied recovered carbon black and steel, recycled materials developed and produced through co-creation efforts.

Lummus Technology, a global leader in process technologies and energy solutions, has signed a memorandum of understanding (MoU) with InnoVent Renewables to support the licensing and worldwide deployment of InnoVent’s continuous tire pyrolysis technology. The collaboration aims to convert end-of-life tires into renewable, high-value products on a global scale.

“This is another significant step in expanding and strengthening our portfolio for the circular economy,” said Leon de Bruyn, president and chief executive officer of Lummus Technology. “By combining InnoVent’s tire recycling technology with Lummus’s global licensing and engineering expertise, we will be addressing the global challenge of waste tires and creating new pathways for sustainable product development.”

Under an agreement outlined in the MoU, once finally negotiated, Lummus will serve as the exclusive licensor for InnoVent’s proprietary continuous tire pyrolysis technology, which converts end-of-life tires into valuable products such as pyrolysis oil, gas, recycled carbon black and steel.
