Paul Lloyd: “Farrel Pomini’s core business lies in supplying processing equipment for the plastics and petrochemical industries."

Pyrolysis has long been associated with pollution and inefficiency, particularly in developing markets where outdated methods dominate. However, technological advancements and a stronger push for circularity are transforming this perception. HF Group, through its subsidiary Farrel Pomini and WF Recycle-Tech, is at the forefront of this shift, introducing a continuous pyrolysis system that promises cleaner and more efficient tyre recycling. Unlike traditional batch processing, its technology ensures consistent output, better resource recovery and reduced emissions.

Pyrolysis has always been considered to be a dirty business. However, with the changes in technology and the increasing hunt for circularity across the tyre industry, businesses are attempting to redefine the age-old tyre recycling process and remove the malice associated with it.

Farrel Pomini is one such entity with the HF Group that is attempting to make pyrolysis cleaner. WF Recycle-Tech, established in 2013, started commercial operations in 2022 with selling its first pyrolysis unit in 2024, slated to be operational in 2026.

Speaking to Tyre Trends, President Paul Lloyd said, “Farrel Pomini’s core business lies in supplying processing equipment for the plastics and petrochemical industries. While its continuous mixer can be used for rubber applications, it is primarily designed for plastic masterbatches and compounds. The company operates across multiple divisions with its plastics compounding equipment focusing on niche applications for highly filled and temperature-sensitive materials. Although the plastics market is significantly larger than the rubber sector, Farrel Pomini targets specialised segments within it. Expanding its footprint in sustainability, the company has developed recycling systems for both plastics and rubber. The end-of-life tyre recycling solution was developed in collaboration with its group company, WF Recycle-Tech.”

Tyre pyrolysis has long been regarded as a polluting industry, particularly in developing countries where unregulated plants often operate at night to evade environmental scrutiny. In markets like India, many such facilities shut down due to non-compliance, reinforcing the industry’s reputation as a ‘dirty business’.

Lloyd further explained, “In Europe, the focus is shifting towards sustainability, driving innovation in pyrolysis technology. Traditional methods relied on large kilns, where tyres were burned with external heat over extended periods. The process was inefficient, labour-intensive and environmentally damaging, requiring extensive manual cleanup.

HF Group has taken a different approach, developing a continuous pyrolysis system that eliminates these challenges.”

Instead of batch processing, the system ensures a constant flow of material, allowing for the controlled capture of gases, liquids and solid outputs. The process begins with pre-grinding tyres into metal-free rubber crumb (6–20 mm), which is then fed into the machine via a hopper. Operating at a capacity of 1,500 kilogrammes per hour, the system requires only continuous material input while automatically managing output streams including recovered oil and gas.

Apropos to the pain points that the company wanted to address, he noted, “Over the past decade of developing this solution, several key learnings and priorities emerged. First and foremost, the goal was to create an efficient pyrolysis system that could consistently process tyre waste at an industrial scale. Second, the decision to develop a continuous rather than batch-based system was fundamental as continuous pyrolysis offers greater consistency, scalability and efficiency. Third, integrating a continuous mixer in the pre-processing stage became a major focus as it significantly improved the homogeneity and quality of the output materials. Finally, optimising the recovered output, particularly recovered carbon black, became the primary objective. Initially, the project was focused on tyre-derived oil (TDO), but as the market evolved, the emphasis shifted to producing the highest-quality rCB, aligning with upcoming ASTM standards and stringent industry requirements.”

By integrating advanced processing controls, the solution ensures cleaner, more efficient pyrolysis, positioning itself at the forefront of sustainable and cleaner tyre recycling.

THE OUTPUT

HF Group’s expertise in mixing technology creates a natural synergy between its traditional business and its expansion into tyre recycling. While the company is known for its tyre curing and rubber mixing solutions, it also has a plastics mixing division; this same mixing technology plays a crucial role in its pyrolysis process.

The recycling system starts with tyre crumb, which is fed into a high-shear Farrel Continuous Mixer originally designed for plastics processing. The mechanical shear heating raises the temperature of the material to 330 degrees Celsius. This ensures uniform heating before the material enters the pyrolysis chamber, where temperatures increase to between 520 degrees Celsius and 580 degrees Celsius. The continuous system eliminates inefficiencies seen in traditional batch pyrolysis, where prolonged heating cycles lead to higher energy consumption and inconsistent output.

Material recovery is a key advantage of the system. For every tonne of tyre crumb processed, approximately 50 percent is converted into pyrolysis oil, yielding 550–570 litres. Around 40 percent becomes recovered carbon black (rCB), a critical raw material that can replace virgin carbon black in industrial applications. The remaining 10 percent is gas, which can be used to power the system, further improving energy efficiency.

Beyond throughput, the system’s design significantly reduces overall energy demand. Mechanical shear heating minimises reliance on external thermal energy, while the continuous process prevents heat loss and optimises fuel efficiency.

Additionally, rCB from the pyrolysis process requires 60–70 percent less energy to refine, further enhancing sustainability.

“Pyrolysis fundamentally relies on heat and time in the absence of oxygen. Under these conditions, tyres thermally degrade, breaking down into vapour, which is condensed into oil and a solid residue, which is now widely used as recovered carbon black (rCB). This output can be further refined for industrial applications, creating a circular economy within the rubber industry,” explained Lloyd.

CHALLENGING INTEGRATION

The primary challenge for tyre manufacturers in adopting rCB is achieving performance characteristics comparable to virgin carbon black. Similarly, tyre pyrolysis oil must meet stringent quality standards to serve as a feedstock for high-value applications beyond just fuel. The company’s continuous pyrolysis system addresses these concerns by enhancing the quality and usability of both outputs.

“In the case of tyre pyrolysis oil, if used as a fuel, the calorific value may vary slightly, but it remains a viable option. However, its greater potential lies in serving as a feedstock for sustainable carbon black or even virgin carbon black production. The consistency of the oil’s composition determines its suitability for high-end applications, making process control a critical factor,” noted Lloyd.

He added, “For rCB, higher quality directly translates into increased usability across different applications. While rCB will never completely replicate virgin carbon black, superior grades enable a higher substitution rate. In some cases, a high-quality rCB can replace up to 30 percent of virgin carbon black, whereas lower-quality alternatives may only allow a 15 percent substitution. This increased usability not only enhances sustainability but also raises the material’s commercial value.”

HF Group’s rCB, produced through its WF Recycle-Tech process, has been extensively tested across multiple industries. It has demonstrated strong performance in plastics masterbatch applications, technical rubber goods and even tyre manufacturing. One major tyre producer has already validated its suitability for substitution in new tyres, underscoring its industry acceptance.

A key differentiator of the process lies in its patented two-stage pyrolysis system. While continuous pyrolysis itself is well established, HF Group’s innovation stems from its integration of a high-shear Farrel Continuous Mixer in the first stage.

This approach ensures uniform heating, eliminates direct heat exposure and optimises the pyrolysis reaction in the second stage. The result is a more efficient process that yields higher-quality recovered carbon black and cleaner tyre pyrolysis oil.

PERSEVERING THROUGH LIMITATIONS

The primary limitations of the system, Lloyd noted, revolve around scalability, operational efficiency and material consistency. The current processing capacity of 1,500 kilogrammes per hour is relatively low. Scaling up production rates while maintaining efficiency and reliability is an ongoing challenge. The key challenge is ensuring long-term operational stability and optimising run times.

Another significant factor is feedstock variability, particularly in markets like India, where used tyres from different sources such as passenger cars, trucks and buses are often mixed without segregation. The ideal scenario would involve processing a uniform type of tyre with a consistent rubber composition, but in reality, recycling operations must work with what is available.

“There are two main approaches to addressing this viz-a-viz meticulous sorting, which ensures consistency but is time-consuming and costly, or strategic blending, which creates a stable output by balancing material variations. The current system has been designed to handle diverse feedstocks without sorting, using a consistent blend of tyres to produce a predictable output,” said Lloyd.

In the long term, technological advancements such as artificial intelligence or tracking mechanisms for tyres could enhance sorting processes, making recycling operations more efficient. However, for now, the focus remains on refining the system to handle real-world feedstock conditions while delivering high-quality outputs. The continuous processing system also provides flexibility to adjust parameters and optimise results, making it a robust solution even in environments where feedstock quality is unpredictable.

MARKET TALK

The return on investment for pyrolysis systems is quite favourable, but it carries risks, especially in the early stages. A well-managed system operating efficiently for 6,000–7,000 hours per year, with a stable feedstock supply and consistent product quality, can generate strong financial returns, explained the executive.

However, challenges arise if there are interruptions in material supply, equipment downtime or fluctuations in product quality. These factors introduce uncertainty, which can make securing financing more difficult. That said, the market for TDO and rCB is growing, providing ample opportunities for revenue. Companies that can differentiate its output and meet quality standards can command premium prices, further improving ROI.

The market focus for HF Group’s advanced pyrolysis solutions primarily includes recyclers looking to add more value to their processes, material users such as tyre manufacturers and technical rubber companies seeking sustainable raw materials and new businesses emerging in response to industry needs.

“In the US and Europe, there is a growing entrepreneurial push to bridge the gap between traditional recycling and the sustainability requirements of the tyre industry. However, in markets like India and other parts of Asia, the challenge lies in shifting perceptions. Many existing pyrolysis operations use older-generation systems. The transition to modern, cleaner and more efficient systems requires education, proof of performance and financial support. Despite these challenges, India remains a strong market for HF, as the industry values high-quality technology and is willing to invest in the best solutions once the benefits are clearly demonstrated,” informed Lloyd.

Over the next five years, the company’s primary goal is to establish a proven track record with the first full-scale pyrolysis system, demonstrating its performance, reliability and efficiency. Once this is achieved, the focus will shift to helping potential customers secure financing by reducing perceived risks, making it easier for them to invest in the technology.

Alluding to the next phase of development, Lloyd informed, “The next phase of development focuses on three main areas. The first priority is industrialising the system to ensure it operates efficiently, consistently and reliably over long production cycles. This transition from pilot-scale to full-scale manufacturing is where HF Group’s expertise in engineering advanced processing equipment comes into play. Secondly, efforts are underway to further refine the pyrolysis reaction to enhance output quality and efficiency. Lastly, ongoing research and development is focused on post-processing improvements, particularly the removal of ash from recovered carbon black to increase its usability in high-performance applications.” n

The Rubber Board of India has launched a series of educational videos as part of the iSPEED (INROAD Skilling and Production Efficiency Enhancement Drive) programme, an INR 1.50-billion initiative aimed at enhancing skill development, quality improvement and infrastructure building within the natural rubber sector. This launch comes as the plantation activities under the larger Project INROAD (Indian Natural Rubber Operations for Assisted Development) in Northeast India approach completion, shifting focus towards productivity and quality enhancement through modern training and facilities.

The newly released video series targets nearly 300,000 rubber growers in the region, covering five essential processing areas: Rubber Tapping, Rain Guarding, Grading, Rubber Sheet Making and Scientific Smokehouses. To ensure broad accessibility, the modules have been produced in Assamese, Bengali, Hindi and Malayalam, enabling effective communication with diverse stakeholders across the natural rubber ecosystem.

The official release of the videos was conducted by Executive Director M Vasanthagesan, alongside Rubber Production Commissioner Dr Siju T Nair, other senior Board officials and representatives from the Indian tyre industry. Developed over the past year with technical assistance from the Rubber Board and the Rubber Research Institute of India, the educational content combines animation with real-life field demonstrations to simplify complex scientific practices for easy adoption.

Project INROAD represents a unique collaboration between the Indian tyre industry and the Rubber Board, with support from Apollo Tyres, CEAT, JK Tyre and MRF. Over the last five years, this partnership has facilitated new rubber plantations across approximately 180,000 hectares in 113 districts of Northeast India, establishing it as the country’s largest plantation development programme of its kind.

Mohan Kurian, Chairman, INROAD Project, said, "Skill development and adoption of scientific practices are essential for improving both productivity and quality in the natural rubber sector. These multilingual videos will serve as an effective training resource for growers and complement the Rubber Board's ongoing extension efforts across the country.”

Sanjiv Saxena, Convener, ATMA Supply Chain & Resources (SCR) Group, said, "The objective of the participating member companies under INROAD is to ensure that rubber growers benefit the most from a stronger natural rubber value chain. By improving productivity and quality, we aim to help farmers realise better returns while strengthening the sustainability of the entire ecosystem."

Muraligopal, who played a key role in coordinating the development of the videos, said, "These videos are the result of close collaboration with the Rubber Board, RRII and field teams across the Northeast. Their guidance and support helped us develop practical, farmer-friendly training modules based on scientific best practices."

Zeon Corporation has finalised the construction of a new bench-scale facility at its Tokuyama Plant in Shunan City, Yamaguchi Prefecture, dedicated to advancing the efficient production of butadiene from sustainable ethanol sources. The project, which broke ground in July 2025, represents a strategic move to establish a naphtha-independent raw material supply chain, thereby bolstering both corporate sustainability and the broader transition towards a carbon-neutral society. The facility is slated to commence full-scale operations in January 2027, with the ultimate goal of achieving commercial viability by 2034.

A commemorative ceremony took place at the plant site on 31 July 2026, drawing a total of 46 attendees. The gathering included official representatives from Japan’s Ministry of Economy, Trade and Industry (METI), the New Energy and Industrial Technology Development Organization (NEDO) and local governmental bodies from Yamaguchi Prefecture and Shunan City. Also present were delegates from the Yokohama Rubber Company, the construction contractor and various affiliated firms, alongside Zeon’s leadership, including Akira Honma, the Corporate Officer and Tokuyama Plant Manager.

This initiative forms one half of a dual-themed research and development programme undertaken in partnership with Yokohama Rubber, under the auspices of NEDO’s Green Innovation Fund. The collaborative effort is focused on the social implementation of technologies for synthesising both butadiene and isoprene from renewable biological materials by the 2030s. As part of this process, Zeon is set to produce a prototype polybutadiene rubber using the output from the new bench-scale facility, while Yokohama Rubber will subsequently manufacture test tyres from this material and conduct performance evaluations on test tracks.

Both companies have outlined a clear roadmap, intending to finalise the core technology for societal deployment by 2030 through the operation of a larger pilot plant, with full-scale commercialisation targeted for 2034. The bench-scale facility is a critical precursor in this phased approach, providing essential data for the scale-up process.

The broader project encompasses two selected NEDO themes, both subsidised through the Green Innovation Fund. The first involves the highly efficient synthesis of butadiene from ethanol, with technical cooperation from the National Institute of Advanced Industrial Science and Technology. The second focuses on biotechnological pathways to directly produce butadiene and isoprene from plant-based materials, involving partnerships with the Institute of Science Tokyo and RIKEN. Both tracks aim to supplement synthetic rubber feedstocks and support closed-loop recycling, aligning with Japan’s 2050 net-zero emissions goal by fostering long-term industrial innovation.

The Association of Natural Rubber Producing Countries (ANRPC) has released its Monthly Natural Rubber Statistical Report for June 2026, a month defined by price resilience amid conflicting market forces. The provisional reopening of the Strait of Hormuz triggered a sharp 20.29 percent drop in Brent crude oil prices to USD 85.40 per barrel. However, this bearish signal was counterbalanced by persistent supply constraints from El Niño-related weather disruptions across major producing regions.

Physical rubber prices posted broad-based gains across most grades. SMR-20 rose 1.39 percent to USD 2.32 per kilogramme, while STR-20 gained 2.61 percent to USD 2.55 per kilogramme. RSS-3 and RSS-4 advanced 4.98 percent and 5.88 percent to USD 3.09 and USD 2.84 per kilogramme, respectively, though latex eased 1.44 percent to USD 1.94 per kilogramme. On the trade front, China's imports surged 7.14 percent month-on-month, while India and Viet Nam declined. Export growth was recorded for Cambodia, Viet Nam and Indonesia, though Thai shipments contracted.

Global production for 2026 is projected at 15.310 million tonnes, up 2.3 percent from 2025, driven by gains in Thailand, China, India and Malaysia. However, June output fell 3.7 percent year-on-year to 1.207 million tonnes due to seasonal wintering and El Niño-related weather disruptions. Malaysia, Indonesia and Cambodia have introduced new incentive and governance measures to strengthen their sectors. Global consumption is forecast to grow 0.7 percent to 15.411 million tonnes in 2026, with June consumption rising 3.3 percent to 1.300 million tonnes, led by China and India amid steady tyre and EV-related demand.

Currency markets saw the Malaysian ringgit trade between RM3.96 and RM4.08 against the US dollar, while the Thai baht ranged from 32.56 to 33.24. In futures trading, the SHFE September 2026 contract averaged 17,580.68 CNY per tonne, down 0.45 percent month-on-month, while the SGX September contract averaged USD 2.24 per kilogramme, up 1.75 percent, with both reflecting tightening supply and firm downstream demand.
