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

The ANRPC Statistics and Information Committee (ISC) presented an updated perspective on the global supply-demand landscape for 2025 and examined updated 2024 statistics and growth rates during the October 2025 Annual Assembly Sessions. September saw price volatility and pressure as output increased while demand stayed low. However, tapping activities were limited in several producing regions due to rains and labour limitations, which contributed to a passive production rise that was not anticipated during the peak production season.

Global natural rubber (NR) output is expected to increase slightly by 1.3 percent in 2025 compared to 2024, according to recent reports from ANRPC member nations, after Indonesia's production base was revised downward. Concurrently, it is anticipated that NR demand would increase by 0.8 percent in 2025 due to an increase in Indonesia's consumer base. Although there were some indications of recovery in the tyre sector in a few countries, market mood remained divided.

In a significant advancement for materials science, Shin-Etsu Chemical has pioneered a new class of thermoplastic silicone, effectively overcoming the longstanding recyclability challenges associated with conventional silicone rubber. This innovation is a core component of the company's Silicones Solution-Engineering initiative, which leverages sophisticated silicon chemistry. Traditional materials are broadly categorised as thermoplastics, which can be remelted and recycled, and thermosetting plastics, which undergo a permanent hardening process that prevents recycling. Standard silicone rubber falls into the latter, thermosetting category.

This newly engineered thermoplastic silicone, however, represents a paradigm shift. It retains the desirable soft texture of silicone but introduces a suite of previously unattainable properties. The material is not only fully recyclable due to its thermoplastic nature but also achieves a unique combination of high hardness and exceptional elasticity. Furthermore, its composition allows for excellent transparency and ease of colouring, as it requires no inorganic fillers like silica. From a manufacturing perspective, it offers excellent processability, suitable for standard plastic injection moulding and even formulation into solvent-based coatings for diverse applications.

The potential uses for this material are extensive and novel. It is expected to enable new applications in consumer electronics, such as soft-touch components for mobile devices and sports equipment, and in the medical field for protective coatings on caregiving devices. By offering a spectrum of properties from rubber-like elasticity to plastic-like rigidity, Shin-Etsu can provide highly customised solutions. The product is scheduled for its first public reference display at the 14th PLASTIC JAPAN exhibition, taking place at Makuhari Messe from 12 to 14 November 2025.

In a strategic move to secure its supply chain, Aluminium Bahrain B.S.C. (Alba) has entered into a partnership with India's Epsilon Carbon. The two companies have signed a non-binding Memorandum of Understanding to explore a long-term arrangement for the supply of liquid coal tar pitch, a critical raw material for aluminium smelting.

This initiative, launched at the Gateway Gulf Forum 2025 in Bahrain, is designed to enhance Alba’s operational security and efficiency. Concurrently, it supports Epsilon Carbon's strategy to establish a new coal tar pitch melting facility within the Kingdom of Bahrain. The agreement paves the way for future detailed negotiations, which will include trial deliveries and the finalisation of quality and commercial terms.

Ali Al Baqali, CEO, Alba, said, “Our collaboration with Epsilon Carbon marks an important milestone in Alba’s journey to reinforce supply chain reliability and maintain the highest standards of quality. This partnership not only secures a key input for our operations but also supports the growth of Bahrain’s industrial sector. We are confident that this alliance will deliver lasting value for both organisations.”

Vikram Handa, Managing Director, Epsilon Carbon, said, “Our collaboration with Alba is an important step toward sustainable industrial growth. With our coal tar distillation capacity set to reach 750,000 tonnes by 2027 and a USD 20 million investment in the Kingdom of Bahrain, we aim to strengthen regional collaboration and supply chain resilience. This will not only reinforce the India – Kingdom of Bahrain industrial corridor but also help reduce the carbon footprint and realise our vision for a more sustainable and efficient aluminium industry.”

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.
