The Rubber Board, which is observing its 77th anniversary this year, organised a press conference to showcase a novel method developed by the Rubber Research Institute of India (RRII) for recovering high-quality rubber from skim latex.

The new technique creates rubber lumps by treating the skim latex with a specific chemical mixture for 24 hours, then allowing the acid to coagulate. After that, these lumps may be dried and turned straight into skim crepe. About 3–4 percent of the rubber used to make Centrifuged Latex (Cenex) is skim latex, a by-product of the process. Cenex is frequently used in the production of goods including balloons, condoms, and gloves. About 10 percent of the natural rubber produced in India is converted into Cenex via centrifugation, which is accomplished at more than 40 centrifuging facilities.

The current method for recovering skim rubber is the acid coagulation of skim latex, which produces a slurry of skim rubber. After being packed into many plastic sacks, this slurry is allowed to solidify and dewater for two weeks. Skim crepe is made by further processing the resultant skim powder. But this traditional approach is labour-intensive, unrefined and results in bad odours, and it only generates rubber of poor grade. It has also caused public outcry and legal conflicts in the vicinity of Cenex enterprises, and it presents difficulties for wastewater treatment facilities. With the innovative method created by RRII, plastic bags are no longer used and processing takes only twenty-four hours. In addition to improving environmental sustainability and guaranteeing full recovery of premium rubber from skim latex, it drastically reduces offensive odours.

The Federation of Latex Processors (FLP), a group of owners of centrifuged latex factories, has been granted access to this technology on a fee basis. Other organizations and Cenex units can also purchase it. The product is marketed as Indian Purified Skim Rubber (IPSR) by the Rubber Board, which is also working on a patent for the concept. Rubber companies nationwide have expressed a strong interest in employing IPSR in product manufacture as it provides a competitive edge because of its improved quality and reduced cost.

Several efforts to solve various problems that exist in the rubber value chain were also addressed at the press conference. At the press conference, it was revealed that a nationwide celebration of the Silver Jubilee of the National Institute for Rubber Training (previously the Rubber Training Institute) would be organised, with participation from all relevant parties. M Vasanthagesan IRS (Executive Director, Rubber Board), Dr T Siju (Rubber Production Commissioner), Dr M D Jessy (Director-in-Charge, Rubber Research Institute of India) and representatives of the Federation of Latex Processors were in attendance.

Cabot Corporation said it can now produce circular reinforcing carbons in the Asia-Pacific region after validating manufacturing capability at its plants in Cilegon, Indonesia, and Tianjin, China.

The materials are produced using tyre pyrolysis oil derived from end-of-life tyres and an International Sustainability & Carbon Certification (ISCC) PLUS mass-balance approach. With the addition of the two Asian sites, Cabot said it now has circular reinforcing carbon production capacity across Asia, Europe and the Americas.

Tyre manufacturers are pursuing targets to increase sustainable material use in tyre production, with many aiming for 40 per cent by 2030 and 100 per cent by 2050, the company said. Cabot’s circular reinforcing carbons are designed as a drop-in replacement for conventional carbon black, allowing manufacturers to increase sustainable content without affecting tyre performance.

Aatif Misbah, Vice-President and General Manager for sustainable solutions in Cabot’s reinforcement materials segment, said: “This achievement reflects our deep commitment to delivering sustainable solutions across Asia Pacific and globally. Scaling our circular reinforcing carbon capabilities helps strengthen our role as a trusted partner to the tire industry, while helping to drive meaningful sustainability progress. Looking ahead, we remain focused on supporting our customers’ evolving needs and helping enable a more sustainable future.”

Cabot’s facilities in Ville Platte, Louisiana; Mauá, Brazil; and Valasske Mezirici in the Czech Republic had previously demonstrated circular reinforcing carbon production capability. The products are ISCC PLUS-certified and marketed under the recovered category of Cabot’s EVOLVE Sustainable Solutions platform.

The company said it has 13 ISCC PLUS-certified sites supporting circular reinforcing carbon production across Asia, Europe and the Americas, along with two certified masterbatch and compounding sites in Europe.

The Rathi Group has formalised a partnership with the Indian Tyre Technical Advisory Committee (ITTAC) through a Memorandum of Understanding aimed at advancing technical collaboration on recovered carbon black (rCB). The agreement focuses on the responsible integration of rCB into tyre manufacturing, with an emphasis on detailed evaluation and enhancement of its material properties. This initiative will be driven through structured engagement between industry and academia, supported by ITTAC’s technical expertise.

The collaboration is facilitated by the Automotive Tyre Manufacturers’ Association (ATMA) and ITTAC, which have brought together leading technical experts, tyre manufacturers and research institutions on a unified platform. Their coordinated efforts are fostering a science-based approach to accelerate the assessment and adoption of circular materials within the tyre sector. This partnership is seen as a significant step in strengthening industry–academia linkages to advance sustainable practices.

Through this alliance, the Rathi Group aims to contribute to the evolving landscape of tyre-to-tyre circularity. The joint initiative underscores a shared commitment to developing innovative solutions that support environmental responsibility while maintaining technical performance standards in tyre applications.
