A major new academic and industry reference, Sustainable Materials for Rubber and Allied Industries, has been released by CRC Press/Taylor & Francis. The 724-page volume brings together science, technology, policy and industrial practice to explore how one of the world’s most essential material sectors is transitioning towards sustainability.

The rubber industry plays a critical role in mobility, healthcare, defence, infrastructure and consumer products. Yet, for decades, most rubber compounds have relied on fossil-based feedstocks and additives. As the world confronts the realities of climate change, resource depletion and waste accumulation, the industry now finds itself at the centre of global discussions on sustainability and circularity.

This book addresses that challenge directly, not as a philosophical concept but as a practical and scientific journey. It examines the material, processing and policy transitions required to build a sustainable future for rubber and tyre manufacturing.

What the Book Contains

Structured across fourteen detailed chapters, the volume covers:

• Foundations of Sustainability and Circularity — explaining environmental, social and economic drivers shaping modern material science.
• Natural Rubber — explored as the industry's most significant renewable resource, along with sustainability challenges in cultivation and processing.
• Bio-Based and Sustainable Synthetic Rubbers — highlighting advances in monomers and green polymer chemistry.
• Sustainable Fillers, Fibres and Reinforcements — including biomass-derived fillers, recycled fibres and improved steel cord systems.
• Curing Systems, Antidegradants, Resins and Processing Aids — re-examined through environmental performance, toxicity and lifecycle impact.
• Thermoplastic Elastomers and Thermoplastic Vulcanisates — offering recyclable and energy-efficient solutions for multiple applications.
• Recycling, Devulcanisation and Circular Economy Models — reviewing the state of the art and emerging industrial-scale technologies.
• Global Regulation and Policy — outlining responsibility frameworks and sustainability compliance trends.

Throughout the book, laboratory research, practical industrial experience, and case-study insights are blended to provide a realistic and applicable reference for scientists, engineers, educators, sustainability strategists, and manufacturing leaders. The work recognises the progress already made by leading manufacturers while setting a scientific and technological roadmap for the years ahead.

The message is clear: sustainability is not merely a direction for the rubber industry — it is its future operating principle.

Bekaert has launched a sustainability label, inhera, to identify its top-performing solutions designed to help customers accelerate progress towards net-zero targets. The label is applied to products that meet defined criteria, including alignment with the EU Taxonomy Regulation, carbon-emission reduction, improved resource efficiency and support for circularity. Eight solutions currently carry the label.

The company said the initiative responds to rising expectations for transparency and credible sustainability claims. It presents inhera as a means of offering clearer information on the impact of its solutions across sectors including construction, automotive and energy.

The name reflects Bekaert’s stated commitment to integrating sustainability across its operations. Ann-Françoise Versele, Vice-President Sustainability, said: “Sustainability is inherent in everything we do at Bekaert. Through our products and processes, we aim to leave a legacy of sustainability for future generations. Our partners who choose inhera solutions are choosing to accelerate sustainability and create real impact.”

The eight labelled solutions include Ampact copper magnet wire for high-voltage electric-motor stators, which the company says delivers a 10 per cent reduction in direct CO₂ emissions. Flexisteel hoist ropes for elevators are designed to cut daily energy use by up to 36 per cent compared with traditional steel ropes.

Elyta Ultra and Mega Tensile tyre reinforcements provide up to 16 per cent CO₂ savings per tyre and support circular reuse. High-tensile steel cores for overhead power lines reduce steel consumption by more than 30 per cent.

Bezinal Vineyard Plus coatings, made with low-carbon raw materials, deliver more than 50 per cent CO₂ reduction and 14 percent lower life-cycle greenhouse gas emissions. Bezinox non-magnetic armouring wire for submarine power cables is engineered to extend cable life and reduce operating temperatures.

Next-generation hose-wire reinforcement uses 28 per cent less wire and 5 per cent less rubber per hose, resulting in up to 70 percent lower CO₂ emissions, while subsea cable armouring wire made from at least 70 per cent recycled steel offers more than 50 per cent CO₂ savings and is fully recyclable at end-of-life.

Bekaert said additional products will be added to the inhera label as further innovations are developed.

Yokohama Rubber has reported new findings from an international research programme aimed at combating leaf fall disease, a fungal infection that has disrupted natural rubber production in Indonesia, the world’s second-largest supplier.

The results were presented on 9 December at the fifth Joint Coordinating Committee Meeting held at Universitas Indonesia. The initiative, formally titled “Development of Complex Technologies for Prevention and Control of Rubber Tree Leaf Fall Diseases”, forms part of the Science and Technology Research Partnership for Sustainable Development, a scheme run by the Japan Science and Technology Agency and the Japan International Cooperation Agency with support from Japan’s foreign and education ministries.

The project brings together Japanese industry, government and academic institutions, including the national research agency RIKEN, with Indonesian partners. Its objective is to maintain output from smallholders, who account for more than 90 per cent of Indonesia’s natural rubber production. The programme is pursuing several approaches: pesticide-based disease control; the development of disease-resistant clones; and early detection using satellite and drone imagery.

Yokohama Rubber, which uses natural rubber as a principal raw material for tyres, has been involved since the project’s launch in 2020. The company began assessing pesticide effects on rubber quality in 2024, following a screening process. Field tests on large plantations have shown that correctly applied pesticides do not impair the properties of raw or vulcanised rubber. Yokohama Rubber is now contributing to research on how such treatments may affect smallholders.

The group said its “Procurement Policy for Sustainable Natural Rubber” incorporates support for participants across the supply chain, including small-scale farmers. It expects its role in the project to aid the sustainable production of natural rubber and help stabilise smallholder incomes. Yokohama Rubber is also an official partner in a separate SATREPS initiative on using rubber seeds to develop environmentally focused products intended to mitigate global warming and plastic pollution.

Under its sustainability theme, “Caring for the Future”, the company has emphasised links between its commercial activities and broader environmental and social objectives.

Australia has released its first national specification for the use of crumb rubber asphalt on local roads, a move intended to give councils clearer guidance on designing and maintaining light-to-medium-duty networks and to strengthen domestic recycling demand for end-of-life tyres.

The Crumb Rubber Modified Dense Graded Asphalt (CRM DGA) Model Specification for light to medium duty roads was published by the Australian Flexible Pavement Association (AsPA) following collaboration with Tyre Stewardship Australia. The document offers standardised technical requirements for councils, which manage about 75 percent of the national road network — roughly 675,000km of streets and community-level infrastructure.

Existing asphalt standards were largely developed for higher-order state roads, leaving local governments to interpret specifications that did not reflect lower traffic loads or the environmental conditions typical of suburban and regional networks. The new model specification aims to close that gap by setting guidance aligned with the factors that most influence degradation on council roads, such as surface ageing and weather exposure.

The specification promotes the use of crumb rubber modified binders, which can extend pavement life under light-to-medium-duty conditions. Incorporating recycled rubber also aligns with broader circular-economy policies across Australia’s states and municipalities, which are seeking to reduce landfill and illegal dumping while supporting domestic tyre-recycling capacity.

AfPA said the CRM DGA Model Specification V1.0, dated October 2025, is publicly available. It includes requirements for mix design and materials, construction processes such as compaction and temperature control, and performance testing suited to council networks. It also offers practical guidance on integrating reclaimed asphalt pavement content.

Local governments seeking case studies and procurement tools on crumb rubber applications can access Tyre Stewardship Australia’s Crumb Rubber Resource Centre for further technical and project information.
