Cabot Corporation announced the launch of EVOLVE Sustainable Solutions, a new technology platform for advancing sustainable reinforcing carbons.

The company's ambition through this technology platform is to develop products that offer sustainable content with reliable performance at industrial scale by leveraging circular value chains and materials recovered from end-of-life tires, and/or renewable and bio-based materials, and/or processes that reduce greenhouse gas (GHG) emissions.

Resulting from these efforts, Cabot has launched two new products which will be sold as the company’s first-ever International Sustainability & Carbon Certification (ISCC PLUS) certified solutions. 

Increased environmental pressures are driving greater demand for sustainable reinforcing carbon solutions that support a circular, sustainable economy as well as decrease GHG emissions. The introduction of EVOLVE Sustainable Solutions is an important step in Cabot’s journey to develop new ways to create materials that improve daily life and enable a more sustainable future.

Cabot Corporation launches EVOLVE Sustainable Solutions technology platform focused on advancing sustainable reinforcing carbons.

The platform is expected to focus Cabot’s efforts on the development of breakthrough sustainable products and process technologies that deliver the performance, quality, and consistency that the industry requires at scale.

EVOLVE Sustainable Solutions is designed to deliver reinforcing carbons across three sustainability categories including:

• Recovered: Reinforcing carbons from circular value chains that are produced using materials recovered from end-of-life-tires, such as tire pyrolysis oils through an ISCC PLUS mass balance approach or reclaimed carbons co-pelletized with virgin carbon blacks.

• Renewable: Reinforcing carbons made from renewable materials, such as bio-based feedstocks through an ISCC PLUS mass balance approach and from bio-based particles.

• Reduced: Reinforcing carbons made with a reduced GHG footprint from decarbonization technologies, such as emissions capture technologies and other decarbonization processes such as CO2 capture and sequestration.

Cabot has launched two new products powered by EVOLVE Sustainable Solutions under the recovered category, VULCAN 7H-C circular reinforcing carbon and STERLING SO-RC110 circular reinforcing carbon that will leverage an ISCC PLUS certified mass balance approach.

VULCAN 7H-C circular reinforcing carbon is a reinforcing material made from ISCC PLUS certified tire pyrolysis oil derived from end-of-life tires. It delivers optimal dispersibility and extrusion characteristics to rubber compounds and delivers drop-in performance comparable to VULCAN 7H carbon black or ASTM N234 carbon black.

It is suitable for synthetic and natural rubber-based tire treads and industrial rubber products that require excellent wear resistance, such as conveyor belts, solid tires, and other applications that require exceptional abrasion resistance. 

STERLING SO-RC110 circular reinforcing carbon is a semi-reinforcing material containing 10% recovered carbon material. Utilizing Cabot’s co-pelletization technology, STERLING SO-RC110 circular reinforcing carbon combines ISCC PLUS certified recovered carbon material with its STERLING SO carbon black to deliver performance comparable to ASTM N550 carbon black.

It maintains high levels of quality, consistency and processability in rubber compounds, making it suitable for applications that require higher sustainable content without compromising rubber performance, including the sidewalls and under tread compounds in passenger car and light truck tires as well as industrial rubber products such as rubber hoses, construction profiles, engine mounts and belt inner layers.
