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.

A USD 1.4 million equipment enhancement at Liberty Tire Recycling’s Cameron, North Carolina, facility is set to significantly boost its processing capabilities. This upgrade, enabled by the state’s sustainable financial backing of its scrap tyre programme, will allow the facility to handle an extra 3,300 tonnes of material annually, representing nearly 300,000 passenger tyres.

A key improvement is the increased capacity to process truck tyres, which are more challenging to recycle due to their size and durable steel components. The resulting crumb rubber, highly sought after by manufacturers, will be directed towards producing floor mat bases and rubber tiles made entirely from recycled material. This material also serves as a component for athletic tracks, synthetic turf, rubberised asphalt and various moulded products.

This capital investment follows North Carolina’s legislative action to redirect tyre disposal fees into the state’s scrap tyre management system, a move that includes compensating counties for collection and recycling expenses. With North Carolina establishing itself as a centre for tyre recycling, Liberty Tire indicates it is evaluating further multi-million-dollar investments and job creation across its other operations in the state.

WACKER has earned a distinguished ‘A’ rating in the 2025 CDP sustainability assessment for its climate protection management. This is Wacker’s third time in a row on the A list by the global environmental non-profit organisation. Beyond the climate category, WACKER maintained its strong standing in water security, again achieving an A- leadership rating. In the forests category, the company secured a B management-level score. These consistent results highlight WACKER’s ongoing commitment to holistic environmental responsibility and transparent reporting across all key sustainability areas.

The CDP, a globally respected non-profit formerly known as the Carbon Disclosure Project, conducts the world’s premier environmental disclosure system. It annually evaluates thousands of organisations on behalf of investors, using a detailed questionnaire that spans climate change, water security and forests. Scores follow an A-to-F scale, with an A denoting exemplary performance and disclosure.

Among over 22,100 companies evaluated worldwide, WACKER’s top climate score places it in the premier tier. According to CDP, such a rating reflects comprehensive, high-quality data disclosure and robust transformation strategies.

Peter Gigler, Head of ESG at WACKER, said, “We have our sustainability performance independently audited by CDP every year, so we’re very pleased that we were able to maintain our top rating for the third time in a row.”

Midas, Asia’s largest manufacturer of tyre retreading materials, has launched O-rings designed for off-the-road (OTR) tyres, aimed at delivering reliable sealing performance in demanding operating conditions.

The O-rings are manufactured using high-quality natural rubber and are formulated to improve physical properties and ensure dimensional stability. According to the company, the product has been tested over many years in harsh environments and is intended to provide consistent, trouble-free performance in OTR tyre applications.

Midas said only REACH-compliant raw materials are used in the manufacture of the O-rings, underscoring its adherence to safety, quality and international regulatory standards.

Founded 56 years ago, Midas supplies tyre retreading materials to customers in more than 60 countries. The company said the launch reflects its continued focus on developing performance-oriented solutions for the global tyre and retreading industry.

Toyoda Gosei has successfully commercialised automotive weatherstrips using recycled rubber, starting with the new Toyota RAV4. This marks a significant breakthrough in a field where rubber has historically been difficult to reuse, often ending up incinerated instead of truly recycled. Unlike steel or plastic, rubber recycling requires devulcanisation, a complex process that traditionally weakens the material and leaves behind unpleasant odours.

Through dedicated refinement of its proprietary devulcanisation technology, the company has overcome these longstanding quality hurdles. The advancements have dramatically increased the usable proportion of recycled material in automotive parts from under five percent to 20 percent, an achievement honoured by a Toyota Motor Project Award.

Looking ahead, Toyoda Gosei aims to extend this technology beyond synthetic rubber to include natural rubber, which is used in far greater volumes. The broader corporate ambition is to collaborate with automakers and partners to establish a full circular system. This system would collect and regenerate rubber from end-of-life vehicles, positioning the company as an industry leader in enabling both decarbonisation and sustainable resource circulation.
