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.

Ecolomondo Corporation, a Canadian developer of sustainable technology for recycling scrap tyres, is reporting significant commercial progress at its Hawkesbury TDP facility. The company is experiencing a substantial rise in demand for its recycled products, leading to strong sales growth.

A key development involves a major customer who, since mid-July 2025, has purchased 12 truckloads of recovered carbon black (rCB), representing approximately 276 metric tonnes. This client has signalled its intention to increase order volumes further as it transitions its business from another supplier. In another positive step, a second US-based customer has formally approved Ecolomondo's recovered carbon black for use in its manufacturing supply chain and is anticipated to commence bulk orders imminently. Additionally, the company has successfully shipped its 26th tanker of tyre-derived oil, amounting to 520 metric tonnes with an estimated value of USD 416,000.

This upward trend is reflected in the financial results. For the period from 1 January to 31 August 2025, revenues reached USD 640,986, a 91 percent increase compared to the USD 336,078 recorded during the same timeframe in 2024. This growth is largely attributed to the rising sales of recovered carbon black. To support the escalating production needs, Ecolomondo plans to hire and train additional personnel for the Hawkesbury facility. The company notes that, as expected during this operational ramp-up phase, the facility is not yet generating gross margins and continues to operate at a loss.

Jean-François Labbé, Interim CEO, Ecolomondo Corporation, said, “These milestones demonstrate the reliability of our production and the repeated nature of revenues we are building.”

ARLANXEO has reinforced its commitment to sustainable manufacturing with the recent award of the International Sustainability and Carbon Certification (ISCC) PLUS standard to its Chloroprene Rubber (CR) plant in Dormagen, Germany. This facility, producing materials under the Baypren brand, becomes the company's sixth site to achieve this globally recognised standard, underscoring a corporate-wide strategy for environmental responsibility.

The ISCC PLUS certification is instrumental for ARLANXEO's Eco product portfolio, a growing line of bio-based and circular synthetic rubbers. The certification employs a mass balance approach, which allows for the tracking of sustainable raw materials through the production chain. This system enables the integration of renewable feedstocks into existing manufacturing processes, providing customers with independently verified proof of a reduced carbon footprint in the final product.

Complementing this certified production process is the advanced formulation of specific Baypren grades. The company offers Baypren 616, a sulfur grade engineered for enhanced safety and regulatory compliance. Unlike conventional alternatives, this product is manufactured without nitrosamine-forming chemicals, making it entirely free of these hazardous substances. Consequently, Baypren 616 is not classified as dangerous goods or as toxic to aquatic life, offering a safer solution that aligns with evolving regulatory standards like EU REACH. This dual focus on certified sustainable production and inherently safer product chemistry positions ARLANXEO as a leader in providing responsible rubber solutions to the market.

Edwin van Grootendorst, Global Head – Business Specialty Elastomers, ARLANXEO, said, “The ISCC PLUS certification of our CR plant reaffirms ARLANXEO's ongoing commitment to providing our customers with high-performance rubber.

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.
