The Polymer Industry Cluster, in partnership with The University of Akron (UA), has announced the selected location for a new innovation pilot facility dedicated to provide crucial resource for innovators by offering the specialised space and equipment needed to transition new materials from research to market.

A significant advancement for Northeast Ohio's polymer industry, the new scale-up facility will be built on the UA campus next to the existing National Polymer Innovation Center building. This proximity is designed to foster a powerful collaborative environment, giving users direct access to the centre’s advanced resources and expertise. Its location at the heart of the region's polymer corridor will provide a centralised hub for businesses and researchers across the area.

A primary goal of the initiative is to fill a recognised void in the product development cycle. The facility will offer turnkey operational space for both startups and established companies to conduct initial production runs and refine their manufacturing processes before committing to full-scale commercial operations. This support is vital for de-risking innovation and accelerating the launch of new advanced polymer products.

Funding was secured through a USD 31.25 million award from the State of Ohio's Department of Development, granted under the Greater Akron Polymer Innovation Hub programme. This state investment is further strengthened by an additional USD 10.4 million in matching contributions from local partners. The construction timeline is set to begin in the second quarter of 2026, following the vacating of the current Lincoln Building on the site and pending final state approvals. This project underscores a shared commitment to strengthening Ohio's position as a global leader in polymer science and manufacturing.

Hans Dorfi, Executive Director and Chief Innovation Officer, Polymer Industry Cluster, said, “This project underscores Akron’s position as the hub of polymer innovation. By placing this facility next to NPIC and close by other polymer and engineering labs, we’re ensuring that entrepreneurs, researchers and industry partners have the tools, environment and support needed to transform new ideas into commercial realities.”

UA President R J Nemer said, "The University of Akron is excited to make room for the polymer facility project. As the number one institution in the world for polymer science and plastics engineering, we look forward to working with our Akron area partners to elevate polymer research, expand development and amplify production right here at the UA campus."

Akron Mayor Shammas Malik said, “Locating the Polymer Industry Cluster innovation pilot facility on The University of Akron Campus demonstrates the importance of the University as a force for education and innovation within the pipeline of polymer development from idea to industry. This new addition complements the work of Bounce Innovation Hub, builds a new resource for our industry partners and highlights the City of Akron as the centre of polymer innovation at the state and national level. This new facility will be just a short walk from Akron's Rubber Worker statue in the heart of downtown which illustrates the importance of Akron's rubber past as a foundation for our polymer future.”

Mark Smale, Executive Director – Advanced Polymer Science, Bridgestone Americas and co-chair of the Polymer Industry Cluster, said, “This facility will represent a transformational step for the Polymer Industry Cluster. It will attract start-ups seeking to validate new materials, researchers aiming to commercialise discoveries and established companies looking to innovate without interrupting their current operations.”

Summit County Executive Ilene Shapiro said, “This new facility is not just an investment in physical infrastructure. It’s an investment in the future of our economy.

Recovered carbon black is edging closer to mainstream adoption as ASTM International committee D36 on Recovered Carbon Black develops a new ash content standard, D8621. The test promises to slash analysis times from 18 hours to just a few, a change that could reshape productivity and quality control for tyre makers and rCB producers. Yet the push for faster monitoring also exposes a bigger challenge, as standardisation alone will not guarantee industry-wide adoption. With high capital investment, scaling hurdles and safety considerations, the new method sits at the intersection of technical progress, economic pressure and the tyre industry’s sustainability ambitions.

The ASTM International’s recovered carbon black (rCB) D36 committee developed and published a new standard called D8621, which will improve productivity of tyre makers and also enhance production process monitoring abilities.

Speaking exclusively to Tyre Trends, ASTM D36 Chair and Director of rCB at Circtec, Pieter Ter Haar, said, “The D1506 method was developed for regular carbon black, which typically has an ash content of <1 percent. rCB typically has an ash content between 15 and 30 percent.”

The new standard promises to cut testing times from 18 hours to just a few. Commenting on this, he said, “This rCB-specific test method requires less material, and by operating the furnace at a higher temperature, the rate-of-reaction is optimised for rCB, resulting in the significant reduction in time. Since ash content is one of the important product specifications, reducing the time to obtain results is of great help in quality control of the production process of rCB.”

“The main benefit is the significant reduced time required to obtain ash content information of the rCB sample from a tailor-made test method. The future bias and precision study will have to show if the method also has an improved standard deviation,” he added.

CONSENSUS BUILDING

The method’s creation reflects the convergence of some of the industry’s biggest players. “This standard was created by the globally leading rCB, carbon black and tyre manufacturers who come together in the committee. We will actively try to promote the use of this method going forward both for producers and users,” said Ter Haar.

He argued that the proposed standard could reshape the economics of rCB production, particularly in terms of reducing waste or lowering costs as more process control will typically result in less waste and a quicker ability to adjust feedstock ratio’s when changes need to be made.

“This new method will also help tyre manufacturers analyse rCB faster and this will, however, not likely play a role in competitiveness compared to virgin carbon black,” he stated.

According to Ter Haar, the temperature of the muffle furnace has increased from 550 degrees Celsius to 700 degrees Celsius, which is an important consideration for the manufacturer using this method when it comes to safe execution of this method. Besides, he wasn’t aware of any other potential risks or limitations that need to be considered.

Alluding to how critical is standardisation in gaining wider adoption of rCB within tyre production supply chains from Circtec’s perspective, Ter Haar explained, “Standardisation will not be the silver bullet for better understanding of rCB or overcoming the initial adoption phase of rCB in rubber compounds. However, when it comes to consistent supply of rCB, relevant rCB-specific specifications are crucial.”

SUSTAINABILITY PUSH

ASTM Standard D8621 fits neatly into the tyre industry’s strategic pivot towards greener materials. According to Ter Haar, the new standard is part of the wider industry development of the rCB producers and adaptation to the needs and requirements of the tyre industry for adoption of new raw materials for the construction of tyres.

He pointed to high levels of capital deployment, the emergence of reputable producers across global regions and platforms like ASTM as proof that rCB is on track to become a cornerstone of tyre sustainability.

“There are very few sustainable raw material options available for the tyre industry that seem to be developing into mature industries,” the spokesperson noted, stressing that rCB is now positioned as a key strategic material for fulfilling long-term sustainability and circularity objectives.

Circtec itself is pushing hard to lead the charge. Later this year, the company will open its third European factory in the Netherlands. The facility, built to a scale comparable with regular carbon black plants, is expected to convert around six percent of all waste tyres in Europe into sustainable products once it reaches full capacity.

“We will continue to focus on the global expansion of Circtec and the development of the sector when it comes to regulatory compliance, technical knowledge and producing high-quality rCB at large industrial scale,” he said.

INDUSTRY RECEPTION

The new standard has already won the backing of the tyre industry. “The tyre industry was an active participant in the development and approval process of this new standard,” Ter Haar emphasised.

The benefit is straightforward, which is more precise quality control. “Any time one of the raw material suppliers can improve their quality control, this is welcomed. The main objective of any new standard is that the test method is technically relevant and improves the ability to test rCB’s characteristics that actually correlate to in-rubber performance,” he explained.

For producers, the efficiency gains are significant. At Circtec’s Netherlands plant, for instance, output is expected to reach 10 tonnes of rCB per hour. At these production rates, quick quality control test methods are crucial.

While faster process monitoring will primarily benefit producers with scaled up production capacity, Ter Haar noted that the standard is not necessarily designed to spark innovation in rCB applications beyond tyres such as plastics or coatings.

Crucially, adopting the new standard won’t require expensive technical upgrades. “The benefit of this method and aim during the development is that for most producers or end-users, there would not be a need for any new investments in equipment. This method is based on the use of an affordable ashing muffle furnace with the ability to heat to 700 degrees Celsius,” he said.

ADOPTION DYNAMICS

ASTM standards remain voluntary, but Ter Haar expects uptake to be swift given the operational advantages. “This new standard is a tool to improve the speed of quality control. It is up to the individual parties to adopt this or any other ASTM method. Due to the clear advantages of this method, I would expect both producers and users to welcome using this test method moving forward,” Ter Haar said.

The development also represents a milestone in a broader strategic roadmap. The ASTM committee D36 on Recovered Carbon Black, formed eight years ago, initially issued guidance on which carbon black test methods could or should not be used.

“At the moment, most of the key product performance characteristics of rCB can be determined,” he observed, suggesting that D8621 could be a stepping stone towards a broader suite of rCB-specific standards on par with virgin carbon black testing.

As rCB moves into the mainstream, the combination of industrial-scale production, regulatory support and technical validation is setting the stage for what could become one of the tyre industry’s most significant sustainability transformations in decades.

Members of the Global Platform for Sustainable Natural Rubber gathered for the organisation’s seventh General Assembly, marking what it described as a pivotal year for accountability and member-led sustainability across the natural rubber value chain.

A key development in 2025 was the launch of GPSNR’s risk-based Assurance System, which sets sustainability expectations, introduces independent verification and aims to drive continuous improvement beyond regulatory compliance. The system was developed collaboratively over several years and is intended to provide a globally applicable framework for sustainability in the sector.

At the assembly, end-user companies reaffirmed their support for the Assurance System and agreed on a structured pathway towards full implementation within their category.

“This year marks a turning point for GPSNR,” said Stefano Savi, chief executive of GPSNR. “The Assurance System gives our members a shared and trusted foundation for demonstrating progress across the value chain.”

Members also reflected on the first year of the Shared Investment Mechanism, a model that allows manufacturers to share the costs of large-scale capacity-building projects. The initiative is intended to deliver long-term benefits for upstream participants, particularly smallholder producers.

“Sustainability cannot be achieved by one part of the value chain alone,” Savi said. “By investing together, our members are enabling more inclusive and impactful outcomes worldwide.”

Looking ahead to 2026, GPSNR said it would focus on supporting the implementation of the Assurance System through data collection, member learning programmes, and stakeholder dialogue, to ensure the framework reflects operational realities and different business models.

The assembly concluded with members reiterating their commitment to building more equitable, resilient and sustainable natural rubber supply chains.

The German Rubber Industry Association (wdk) has called for enhanced policies to unlock the full potential of tyre recycling in Germany. While acknowledging the existing successes of the circular economy in this sector, Stephan Rau, Technical Director of wdk, emphasised that significant untapped opportunities remain. Last year alone, Germany generated 533,000 tonnes of used tyres, with nearly 70 percent kept in circulation through reuse, retreading and recycling. The wdk advocates for a stronger framework to improve these material flows and boost the market for recycled materials.

A central pillar of the wdk’s position is the demand for a modern, science-based evaluation of recycled rubber products. Over 200,000 tonnes of used tyres are processed annually into granules and rubber flour, vital secondary raw materials for sustainable manufacturing. However, Rau argues that their broader market success is hindered by outdated assessment methods. The association urgently recommends a risk-based approach that evaluates chemical ingredients based on their actual bioavailability and migration, rather than their mere presence. This perspective, now supported by the German Federal Institute for Risk Assessment (BfR), necessitates establishing binding limit values determined through migration analysis to ensure both safety and commercial viability.

Furthermore, the wdk highlights a critical gap in the complete monitoring of tyre material flows. A notable proportion of used tyres exit Germany and Europe for processing, depriving domestic recyclers of valuable secondary raw materials. To address this leakage and strengthen the circular economy, Rau stresses the need for comprehensive tracking of all end-of-life tyres. The association’s commitment is reflected in its patronage of the Alliance for Future Tyres (AZuR), a European network of nearly 100 partners from industry, trade and science dedicated to advancing a sustainable tyre circular economy across all segments.
