French biotech firm expands into industrial fabrics market through enzymatic PET recycling technology

French biotechnology company CARBIOS has signed a multi-year commercial agreement with Thailand's Indorama Ventures to supply recycled materials for tyre manufacturing, marking the firm's expansion into the industrial fabrics sector.

Under the deal, CARBIOS will provide biorecycled monomers from its planned Longlaville industrial plant to Indorama Ventures, the world's largest polyester producer. The Thai company will transform these materials into recycled polyethylene terephthalate (r-PET) filaments for use in tyre reinforcement by French tyre manufacturer Michelin.

The partnership represents CARBIOS's entry into a new market segment beyond its existing focus on cosmetic packaging applications. The company uses proprietary enzymatic recycling technology to break down complex PET waste into high-quality recycled materials.

"This commercial agreement with Indorama Ventures marks a new step in the realisation of our industrial project," said Vincent Kamel, chief executive of CARBIOS. "It confirms the trust of Indorama Ventures and Michelin in our PET biorecycling technology."

The deal comes weeks after CARBIOS signed its first sales contracts for biorecycled PET with two unnamed global cosmetics companies, as the firm builds momentum ahead of the commercial launch of its Longlaville facility.

Michelin, which has committed to using 100 percent renewable and recycled materials by 2050, said the partnership advances its circular economy objectives.

"This partnership is a tangible expression of our commitment to turning complex waste into high-performance materials," said Fabien Gaboriaud, director of circularity and renewable & recycled materials at Michelin Group. "By integrating enzymatically recycled r-PET into our tyres, we are marking a new milestone on our journey toward achieving 100 percent renewable and recycled materials by 2050."

Indorama Ventures, which generated $15.4 billion in revenue last year, said the alliance underscores its commitment to circular economy principles. The company employs approximately 25,000 people across manufacturing operations in Europe, Africa, the Americas, and Asia Pacific.

"This alliance with both, CARBIOS and Michelin, underlines our commitment to plan ahead and take a leading role in shifting the industry towards circularity," said Renato Boaventura, global market head mobility at Indorama Ventures.

CARBIOS, founded in 2011, has developed enzyme-based biological processes to break down plastics as part of efforts to prevent plastic pollution and accelerate the transition to a circular economy. The company operates an industrial demonstration plant for biorecycling that has been operational since 2021.

Construction of what the company describes as the world's first biorecycling plant is expected to resume in the second half of 2025, subject to securing additional funding.

Mathe Group, a specialist in recycling radial truck tyres, has undertaken a significant multi-million-rand investment in advanced machinery designed to transform steel recovery into a major revenue source. This strategic upgrade focuses on extracting high-purity, or ‘clean steel’, for export to international markets such as India and South Korea, marking a shift from treating steel as a mere by-product to valuing it as a key income stream.

A central part of this investment involves the installation of state-of-the-art de-beading machines. Unlike older methods that damaged the steel rings embedded in tyre sidewalls, this new technology removes the beads entirely intact and free of rubber. This preserves their quality, making them easier to process and package, and allows them to be sold as a premium product for industrial applications like blasting, replacing virgin steel. The first units are already operational, with a third machine scheduled for delivery. These new, electrically-driven de-beaders will also lower maintenance costs and reduce emissions compared to the previous oil-hydraulic systems.

Furthermore, the company is commissioning an in-house clean steel mill with an integrated automated packaging line. Currently, extracted steel is sent to India for cleaning before being forwarded to South Korean manufacturers. By bringing this cleaning process to its Hammarsdale facility, Mathe Group will drastically reduce rubber contamination from 10 percent to under two percent. This enhanced purity means the steel can be bagged and loaded directly into shipping containers for the port of Durban, commanding double the price on the international market because it requires no further reprocessing. The upgraded system is expected to export 108 tonnes of clean steel weekly.

This comprehensive re-engineering of the production process recovers an additional eight percent of rubber crumb from each tyre and is set to create new jobs. The new steel extraction system is projected to be fully operational by January 2026.

Cabot Corporation has released its 2025 Sustainability Report, detailing the company's advancements in 2024 and introducing a new set of objectives for 2030. The report demonstrates significant momentum, with Cabot having already met 11 of its 15 sustainability targets for 2025 ahead of schedule and anticipating further progress on the remaining goals this year.

Notable achievements from the reporting period include a community investment of USD 10 million in its local operating areas and a reduction in greenhouse gas (GHG) emissions intensity by more than five percent, which surpassed the 2025 goal early. The company also reported its highest level of beneficial waste reuse in over six years, diverting significant material from landfills. In product innovation, Cabot launched the REPLASBLAK family, its first black masterbatches to receive International Sustainability & Carbon Certification (ISCC) PLUS. Furthermore, the company reinforced its commitment to reducing plastic pellet loss by securing Operation Clean Sweep Europe certification for its two masterbatch facilities in Belgium.

Looking forward, Cabot has established a new framework of 2030 Sustainability Goals, shaped by a comprehensive materiality assessment conducted in 2024. This assessment involved extensive research, peer benchmarking and consultations with internal teams and external stakeholders to identify six priority areas. The resulting 2030 targets include a 15 percent reduction in Scope 1 and Scope 2 GHG emissions intensity and a 20 percent absolute reduction in sulphur dioxide emissions. The goals also encompass ambitious energy and water management targets, such as exporting 250 percent of the energy the company imports and reducing freshwater withdrawal intensity by 10 percent at sites in water-stressed regions. Additional objectives focus on lowering the average product carbon footprint by five to 10 percent and achieving a 25 percent reduction in safety incident rates.

Developed in accordance with Global Reporting Initiative (GRI) Standards, the full 2025 Sustainability Report, which also supports Cabot's commitment to the United Nations Global Compact, is available for review on the company’s website.
