Tokai Carbon Co., Ltd., Bridgestone Corporation, Kyushu University and Okayama University have started a technology development project to perform secondary processing on recovered carbon black (rCB) extracted from polymer products like end-of-life tyres containing rubber in order to create new eco carbon black (eCB) from these and other sources. With rubber reinforcing qualities comparable to those of virgin carbon black (vCB), which is made from coal and petroleum, the initiative seeks to transform these resources into eCB. Through the development of cutting-edge recycling technologies, the collaborative project partners want to contribute to the attainment of a circular economy and carbon neutrality.

This project is a component of the ‘Technology Development for Carbon Recycling from Polymer Products Including End-of-Life Tires’ demonstration programme, which was put out by Tokai Carbon in collaboration with Bridgestone, Kyushu University and Okayama University. The New Energy and Industrial Technology Development Organisation (NEDO) chose the project on 23 December 2024, under the heading of ‘Green Innovation Fund Project/Technology Development for Manufacturing Plastic Raw Materials Using CO₂ etc’.

In order to recover and utilise rCB, efforts are already in progress to pyrolyse polymer materials, including rubber from tyres that are nearing the end of their useful lives. Nevertheless, there are still obstacles to overcome before rCB may be used practically in new tyres. Because it contains so many contaminants, rCB performs worse than vCB when it comes to rubber reinforcement. Additionally, heat recovery produces CO2 emissions even if many end-of-life tyres are successfully used as fuel. The demand for tyres is predicted to increase in tandem with the projected expansion in the automotive and transportation sectors. The goal of these initiatives is to improve resource circulation by making it easier to recycle vCB, a crucial component of tyres.

Bridgestone, Kyushu University and Okayama University's knowledge and technologies will be combined with Tokai Carbon's own technologies and skills gained from manufacturing carbon black. The goal of the collaborative project is to create technologies that will eliminate impurities from rCB and create eCB with better rubber reinforcing qualities. By fiscal year 2032, the initiative aims to set up a demonstration unit that can produce 5,000 tonnes of eCB annually. The research will also concentrate on creating unique polymer/carbon composites that allow carbon black to be reused without pyrolysing tyres that have reached the end of their useful lives. With these efforts, the collaborative project participants hope to achieve enhanced recycling of scarce materials and contribute to lowering the CO2 emissions linked to the manufacturing of carbon black and the recycling of end-of-life tyres.

Vipal Rubber, a leading global producer of retreading rubber, has reaffirmed its commitment to innovation with the launch of its new V SUPER HYBRID technology. Available from 1 March 2025, this new compound is designed to redefine performance standards for mixed-terrain applications, offering enhanced mileage, durability and resistance for retreaded tyres across various fleet sizes.

The V SUPER HYBRID achieves a superior balance between on-road and off-road performance. It has proven effective in demanding sectors such as logging, grain and livestock transport, demonstrating robust capabilities across diverse operating conditions. Key advantages of the innovation include improved resistance to chipping and punctures, enhanced casing protection that extends tyre service life, lower environmental impact through increased tread utilisation and significant operational cost savings for fleet operators.

Field tests substantiate these claims. In one trial involving a high-torque truck on steep, unpaved terrain, tyres with V SUPER HYBRID technology showed an 11.5 percent increase in mileage over a standard market compound while maintaining structural integrity with no signs of breakage. Furthermore, the same technology demonstrated the potential for up to a 140 percent mileage increase over conventional compounds in continued testing. The tread's regular wear pattern also allowed for better depth utilisation, enabling tyres to remain in operation down to 5-6 mm, compared to the previous limit of 12 mm. Another test with a grain and livestock truck confirmed these results, documenting a 12.5 percent performance gain across different tread designs.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly NR Statistical Report for July 2025, providing an overview of key developments in the global natural rubber sector.

According to the report, natural rubber prices exhibited significant volatility in July. This instability was driven by a combination of adverse weather conditions impacting production, ongoing geopolitical tensions and international trade tariffs. After an initial phase of ample supply and muted demand, market sentiment shifted as concerns over potential supply disruptions prompted a notable increase in purchasing activity.

The report further projects a modest global production increase of 0.5 percent for 2025, while demand is anticipated to grow by a slightly higher 1.3 percent. However, this growth is expected against a challenging backdrop of a potential global economic slowdown. Complex US tariff policies and their widespread ripple effects are primary factors contributing to what may become one of the most subdued years for economic expansion since the pandemic.

Continental is establishing a groundbreaking industrial process for recycling complex rubber waste through a strategic acquisition of key patents and the launch of a new pilot facility. This initiative, led by its ContiTech division, leverages advanced pyrolysis technology to transform end-of-life rubber products into valuable raw materials, creating a sustainable alternative to fossil resources.

The core of this innovation is a thermal decomposition process where waste rubber is heated in a low-oxygen environment. This breaks the material down into its core chemical constituents, one of which is a high-quality oil with properties mirroring traditional crude oil. This output is particularly significant as it can be directly used in the manufacture of new plastics and rubber goods, effectively closing the material loop.

A major historical obstacle for the industry has been the difficulty of recycling vulcanised rubber, whose altered chemical structure resists conventional separation methods. Pyrolysis successfully circumvents this challenge, cleanly decomposing the material to recover not only oil but also carbon black and other energy sources. The widespread adoption of pyrolysis has been hindered until now by the complexity of purifying its outputs to meet industrial standards. Continental’s new facility, originally developed by British start-up LowSulphurFuels, directly addresses this hurdle with a specialised purification process, making large-scale rubber recycling both technically feasible and economically attractive.

This advancement is especially critical for complex rubber products like composite hoses and specialised seals, which were previously nearly impossible to recycle efficiently. By converting this challenging waste stream into a high-grade resource, Continental is driving progress towards a circular economy. This move also reinforces the company's position as a leader in sustainable innovation, complementing its extensive patent portfolio and ongoing projects focused on material recovery and developing eco-friendly solutions for the automotive and industrial sectors.

Dr Michael Hofmann, Chief Technology Officer, ContiTech, said, “With this technology, we’re closing a crucial gap in the circular materials economy: we’re able to recover high-quality raw materials from rubber waste, which we can then feed back into the chemical material cycle to create new products without relying on crude oil. We’re thus demonstrating how innovation can become the driving force behind sustainable industrial processes – and how a previously untapped raw material cycle can be made economically viable.”
