Epsilon Carbon, a leading global manufacturer of carbon black, has launched N134, which it claims is a specialised ‘Hard Grade’ carbon black known for its superior abrasion resistance and durability.

At present, the high-quality N134 grade is being imported due to the lack of consistent quality and supply chain issues in the Indian market. As a result, the tyre makers have to modify their formulations using other grades of carbon black, which it shared often leads to reduced performance.

But now, Epsilon Carbon has become the first company in India to install a dedicated manufacturing unit designed for N134 grade hard carbon. The company is expanding its existing Vijayanagar Carbon complex facility to produce 215,000 tonnes of carbon black.

This will not only ensure consistent supply of N134 carbon black for tyre makers in the country, reduce import dependency, but also open up export potential to markets such as Europe and USA. Epsilon Carbon will also focus on integrate advanced processing techniques to ensure batch consistency for durability and performance.

Vikram Handa, Managing Director, Epsilon Carbon, said, “This is a proud moment for us and for India’s carbon black manufacturing sector as the high quality N134 black will significantly reduce import dependency and provide tire manufacturers in India and abroad with a reliable, high-quality product. Our goal is to match global standards while building India’s capability to serve premium markets.”

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.

Cabot Corporation has launched LITX 95F, a high-performance conductive carbon additive designed for lithium-ion batteries in energy storage systems (ESS). Optimised for residential, commercial and industrial ESS applications, this advanced material enhances conductivity, extends cycle life and improves processability – critical for systems requiring durability under frequent charging and discharging.

With the global ESS market expanding due to renewable energy adoption and demand for grid stability, battery manufacturers need cost-effective, high-performance solutions. LITX 95F meets these needs by boosting energy density and cycle life while maintaining stability. Pouch cell tests with thick electrodes confirm its superior capacity retention, offering manufacturers greater flexibility in ESS design.

The material’s high-structure morphology strengthens conductivity and stability over repeated cycles. Additionally, its compatibility with thick cathode designs helps lower material costs without sacrificing performance. This innovation supports the growing ESS sector by enabling more efficient, reliable and scalable battery solutions.

Jeff Zhu, Executive Vice President and President, Carbon & Silica Technologies, Battery Materials and Asia Pacific Region, said, “As the global energy landscape continues to evolve, the ESS market requires advanced materials that deliver both performance and efficiency. Our new LITX 95F product is a direct response to the needs of the market and our battery customers – leveraging our deep industry expertise with proven performance to help scale ESS applications faster and more efficiently. This launch reflects our commitment to enabling a more sustainable future by delivering innovative solutions for battery technologies that support the energy transition at a global scale.”

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for June 2025, providing an overview of key developments in the global natural rubber sector. The latest data indicates a sustained downward price trend, primarily driven by improving supply conditions in major producing nations, elevated stockpiles at key ports and ongoing trade policy uncertainties.

Market analysts attribute the bearish sentiment to a combination of factors, including increased output from leading rubber-producing countries and subdued industrial demand, particularly from tyre manufacturers. These conditions have contributed to mounting pressure on prices, with limited signs of immediate recovery. The ANRPC notes that while production levels remain stable, cautious demand projections persist due to broader macroeconomic concerns, including potential trade disruptions and slowing global economic growth.

Projections for 2025 suggest a modest 0.5 percent increase in worldwide natural rubber production compared to the previous year. Meanwhile, consumption is anticipated to grow by 1.3 percent, reflecting a slight but uneven recovery across key markets. However, analysts warn that external factors, such as shifting US tariff policies and weaker-than-expected industrial activity, could further dampen demand growth in the coming months.
