Marubeni Corporation has taken a significant step into Thailand’s tyre recycling industry by acquiring a 32 percent stake in Green Rubber Energy, an ELT pyrolysis company. This strategic partnership aims to address the tyre industry’s waste management challenges, foster sustainability and strengthen circular economy practices by producing high-quality recovered carbon black and other recycled materials.

Marubeni Corporation recently forayed into Thailand’s tyre recycling space with investing in Green Rubber Energy (GRE), an end-of-life tyre pyrolysis company headquartered in Samut Prakan.

Speaking to Tyre Trends on the partnership, GRE Chief Executive Officer Mai Auapinyakul said, “Marubeni, with its expansive upstream-to downstream network, has long sought to tackle the waste tyre challenge while addressing sustainability goals for major tyre manufacturers. GRE fills a critical gap in Marubeni’s strategy by stepping in as the recycler, a role previously missing in its ecosystem. The partnership between GRE and Marubeni is built on a foundation of trust, having worked together for over five years in the recovered carbon black (rCB) market. GRE’s expertise and Marubeni’s global reach create a natural synergy, fostering collaboration across the entire supply chain, from producers to recyclers.”

The executive revealed that Marubeni now holds a 32 percent stake in GRE, solidifying its entry into the ELT and tyre pyrolysis business in Thailand. While financial specifics remained undisclosed, she mentioned that this partnership is poised to significantly influence regional tyre recycling markets.

“GRE’s vision to lead as a key technological player in closing the circular economy loop aligns seamlessly with Marubeni’s strategy in tyre recycling. This collaboration marks a pivotal step in transforming the tyre industry’s linear supply chain characterised by ‘make, use and discard’ into a circular one focused on ‘use, remake and recycle’,” said Auapinyakul.

The recycler emphasised that a successful circular supply chain demands a seamless partnership among producers, users and recyclers. As tyre manufacturers push towards sustainability targets such as integrating recycled raw materials into their production processes by 2050, GRE plays a critical role in ensuring the quality and consistency of rCB.

“Recovered carbon black production is inherently tied to the formulation of input tyres, whether truck tyres, eco tyres or passenger car tyres. GRE’s approach underscores that ‘what goes in is what comes out’. Tyre manufacturers’ formulations directly influence the rCB quality GRE supplies back to the industry, making collaboration not just beneficial but essential,” said the executive.

She added, “Marubeni’s extensive network within the tyre manufacturing industry opens new avenues for GRE to meet industry-grade rCB standards. This collaboration fosters innovation and quality assurance while expanding the dialogue on the broader adoption of rCB in both tyre and compounding industries.”

DEMAND FOR RCB GRE’s

ELT recycling process produces three primary commercial products that include rCB, tyre pyrolysis oil (TPO) and steel wires. The rCB produced is equivalent to N660-grade carbon black, offering a sustainable alternative for industrial applications. TPO serves as a versatile byproduct used in fuel and chemical production, while the steel wires extracted during the process are sold to recycling markets.

The company currently focuses on the regional market with most of its rCB distributed within Thailand. However, GRE has begun exporting small quantities of rCB to Malaysia and Japan, indicating the growing international interest in sustainable materials. While regional demand remains GRE’s core focus, the international market offers significant potential for expansion as global sustainability goals and regulations gain momentum.

“In Thailand, the initial demand for rCB was driven largely by its cost advantage over virgin carbon black. Over time, this has evolved as manufacturers, especially those exporting to the European Union, adapt to stringent sustainability regulations that prioritise the use of recycled raw materials. Today, major tyre manufacturers are increasingly incorporating rCB into their production processes to meet their long-term environmental targets, resulting in heightened demand for GRE’s products,” said the official.

Adopting rCB, however, comes with its challenges. “Unlike virgin carbon black, rCB is not a one-to-one replacement due to its molecular differences stemming from the recycling process. Manufacturers must adjust their formulations and production methods to ensure compatibility. This shift in the supply chain mindset requires close collaboration between GRE and tyre producers. GRE has been proactive in addressing this challenge by working with manufacturers to align on product specifications and processes, fostering a ‘two-way street’ approach to innovation,” said Auapinyakul.

Currently, GRE’s plant in Samut Prakan, Thailand, processes around 10,000 tonnes of ELT annually, with Mai Auapinyakul, CEO, Marubeni an output split of approximately 38 percent tyre pyrolysis oil, 32 percent recovered carbon black and 13 percent steel wires. While operating below its full capacity of 13,000 tonnes, GRE plans to scale production in the coming year to meet the rising demand for rCB. With the local market currently using rCB in a 10 to 90 percent ratio compared to virgin carbon black, GRE anticipates this will shift to 30 percent rCB and 70 percent virgin carbon black within five years, signalling a transformative change in the tyre and materials industries.

FINE TUNING

GRE claimed to have achieved notable advancements in stabilising the quality of rCB for tyre applications through the implementation of continuous pyrolysis technology. While pyrolysis itself is not a new innovation, GRE has tailored its processes to prioritise rCB production over TPO, a strategy that sets it apart from many batch pyrolysis operations that emphasise oil production. Over nearly a decade, GRE has fine-tuned its technology to meet the stringent quality and stability requirements of the tyre industry, ensuring the rCB produced is suitable for tyre manufacturing.

Moreover, the collaboration seeks to purify rCB and TPO leveraging technology from Germany’s RCB Nanotechnologies GmbH, in which Marubeni has invested. Commenting on the implementation, the executive averred, “While GRE has not yet worked directly with Germany’s RCB Nanotechnology, the potential for collaboration is significant. GRE sees this as an exciting opportunity to further enhance the quality of its rCB and expand into higher-grade products, unlocking greater value in the sustainable raw materials market. The collaboration is expected to align with GRE’s goal of increasing market share by offering diversified grades of rCB, supported by Marubeni’s investment and resources.”

ENSURING SUPPLY

According to the company, Thailand generates approximately 80,000 tonnes of ELTs annually, with an additional 25,000 tonnes of off-spec tyres classified as waste. Currently, the ELT volume is increasing at a rate of around five percent per year driven by rising vehicle use and tyre turnover. With Marubeni’s expanded network and GRE’s growing capacity, the percentage of ELTs recycled is expected to increase significantly, reducing environmental impact and advancing the circular economy within the region.

Furthermore, the collaboration seeks to ensure a steady supply of the ELTs to GRE. Commenting on the supply chain, Auapinyakul noted, “Marubeni’s involvement brings strategic advantages in securing a consistent supply of ELTs. By leveraging its extensive network, including partnerships with tyre retailers and service providers, Marubeni ensures a steady flow of ELTs for GRE. This network also connects GRE to tyre manufacturers, allowing the collection of off-spec tyres directly from production lines.” “This expanded supply chain not only guarantees raw materials for GRE’s increasing production capacity but also addresses environmental concerns by ensuring ELTs are properly recycled and re-introduced into the market as sustainable products. Marubeni’s support enables GRE to scale its operations while promoting responsible waste management practices in Thailand,” she added.

EXPANDING REACH

Thailand offers a robust ecosystem for establishing a proofof- concept model. The country’s well-integrated tyre industry supply chain provides an ideal environment to demonstrate the feasibility and scalability of a closedloop recycling model. GRE aims to leverage this position by expanding its production capacity in Thailand, focusing on both domestic supply and exports.

The next five to 10 years will see GRE doubling its current maximum capacity to 26,000 tonnes with a clear strategy to expand the applications of its products. Once the model is fully operational in Thailand, GRE and Marubeni plan to adapt and replicate it in other regions, with Japan being a key target. Marubeni’s extensive network and expertise will play a pivotal role in expanding into Japan and potentially beyond the Asia-Pacific.

While the tyre industry remains the primary consumer of rCB, GRE is also exploring other markets.

India’s recycling industry is becoming more technology-driven, formalised and commercially sophisticated, but women remain underrepresented across its operational and technical functions. GRP Ltd Executive Director Hemal Gandhi believes a new generation, increasingly exposed to sustainability and circular-economy thinking, could begin changing that equation. Recently appointed as Chairperson of Material Recycling Association of India’s Women in Recycling Committee, Gandhi is pushing for greater participation, capability building and visibility as the sector moves beyond conventional waste processing towards advanced resource recovery and sustainable-material manufacturing.

A new generation of professionals exposed to sustainability and circular-economy principles will drive greater participation of women in India’s recycling industry, according to GRP Ltd Executive Director Hemal Gandhi, who was recently appointed Chairperson of the Women in Recycling Committee at the Material Recycling Association of India (MRAI).

Gandhi acknowledged that women’s representation across the recycling industry remains limited, particularly outside conventional support functions. However, she sees an opportunity for this to change as second-generation members of recycling businesses enter the sector and younger professionals increasingly encounter sustainability and circularity through universities and education.

“A lot of the second generation has come into the business,” Gandhi told Tyre Trends, adding that the newer generation is more receptive to entering recycling because it increasingly understands the industry’s broader environmental purpose.

For Gandhi, the immediate priorities for increasing women’s involvement are participation, capability building and visibility.

She wants participation to extend beyond corporate and leadership positions into technology, operations, engineering, research and development, entrepreneurship and commercial functions.

“I’d like to encourage greater participation of women across the recycling value chain,” Gandhi said.

She added that stronger platforms for knowledge sharing and mentoring are needed, with mentor circles among the mechanisms being considered to engage a wider audience.

Visibility represents the third element as she wants greater recognition of women already contributing to recycling while strengthening connections between established industry leaders and the next generation.

The broader objective, she said, is to make recycling a more inclusive, professional and future-oriented industry and ensure women have a meaningful role in determining its next phase of growth.

“Women bring extraordinary attention to detail, discipline, resilience and an ability to see both the task and the people around it. But I don’t want women to be valued only for these qualities. I want them at the table, making the big decisions,” noted a confident Gandhi.

GRP’s own experience illustrates some of the barriers. Gandhi said women joining the company’s Sholapur operations were initially concentrated in support functions including administration and human resources.

Changing that required what she described as a ‘mindset shift’ within GRP itself. The company has since expanded their presence into manufacturing.

“We are pros at multi-tasking and know how to get the job done. We’ve successfully represented plenty of industries before and now it’s recycling’s turn to take centre stage,” she said.

Women’s representation at GRP varies across locations based on the job requirement and talent availability. The head office has the largest women participation of 28.57 percent. The reclaim rubber and Pyrova business combined contribute to about 13.30 percent with substantial women participation on shopfloor at all shifts.

The plants in Solapur and Ankleshwar show 19.32 percent and 17.81 percent, respectively, which are far higher than the industry average of 10–11 percent.

The focus is to create opportunities of women participation in the plastics business as well.

BROADENING BASE

The push for broader participation comes as India’s tyre-recycling ecosystem itself undergoes significant change.

Gandhi said tyre recycling now has strong representation within MRAI with participation increasing across the value chain. The ecosystem has expanded beyond conventional scrap processing to include collection, aggregation, mechanical recycling, crumb rubber, reclaim rubber, pyrolysis, devulcanisation, retreading technologies and downstream users.

MRAI’s tyre-focused sessions and programmes have also seen increased participation, according to Gandhi. She sees the association’s role extending beyond industry representation to providing a platform where stakeholders can engage on policy, standards, technology and development of end markets.

The next opportunity, she said, is to deepen representation across the tyre-recycling value chain.

Gandhi described India’s tyre-recycling industry as being at an inflection point with Extended Producer Responsibility emerging as a significant catalyst.

The waste-tyre framework has brought greater attention to end-of-life tyres, encouraged formal recycling channels and provided recyclers with a more structured position within the tyre ecosystem.

More companies entering the sector demonstrate growing interest, but Gandhi cautioned that regulation and creation of recycling capacity represent only the beginning.

“The next phase needs to concentrate on quality, traceability, responsible processing and end markets,” she said, adding, “Industry should not measure success only by how many tonnes of tyres are processed.”

Instead, the sector needs to examine how much material value is recovered from every tyre, the quality of those recovered materials and whether they ultimately enter higher-value applications.

She described EPR as a game changer that has established the framework, while the next challenge is developing a more transparent, technology-driven and circular system around it.

COLLABORATION OVER CONSOLIDATION

India’s tyre-recycling industry has historically been fragmented, though Gandhi believes it is gradually becoming more organised as regulations, technology and market requirements become clearer.

She drew a distinction between consolidation and collaboration.

“Companies operating in collection, dismantling, shredding, pyrolysis and retreading can have significantly different levels of technology and formalisation. The objective should therefore not simply be reducing the number of companies,” she argued.

Instead, India needs a more organised ecosystem with common expectations around compliance, traceability, quality, technology and responsible processing.

More clearly defined standards and EPR requirements will increasingly differentiate companies investing in quality systems and sustainable operations, she said.

Gandhi said the country has several advantages including a large domestic tyre market, substantial availability of end-of-life tyres, rubber-processing capabilities and an increasingly structured policy framework.

There is, however, no single international recycling model India can simply replicate because individual markets have developed around different collection systems, regulations and economics.

The common global direction is towards higher-value material recovery.

Products such as reclaim rubber and recovered carbon black are increasingly being developed as industrial raw materials rather than merely waste-derived outputs.

India is moving in the same direction, Gandhi said, with domestic recyclers already producing such materials and supplying to international markets.

“The opportunity is to combine India’s scale, manufacturing capabilities and entrepreneurial base with global best practices,” she noted.

EXPANDING CAPACITY

GRP, meanwhile, is positioning its recycling operations around recovering greater value from waste materials and developing applications capable of substituting virgin resources.

The company currently operates across five strategic locations and eight manufacturing units with installed capacity of approximately 122,000 tonnes per annum, according to Gandhi.

Its next step into end-of-life tyre recovery is being pursued through Pyrova Energy.

At Sholapur, GRP has commissioned a 15,000-tonne-per-annum continuous tyre pyrolysis reactor alongside an integrated crumb-rubber facility. The next phase includes expanding pyrolysis capacity to 45,000 tonnes per annum and developing recovered carbon black capacity.

The broader objective is to recover the different components of an end-of-life tyre while progressively improving the quality and value of each material stream.

Gandhi also highlighted GRP’s wider sustainability performance. She said the company reduced Scope 4 emissions by 55 percent, while the share of its energy requirements met through renewable sources increased to 48 percent from 37 percent in the previous year.

GRP has also received an EcoVadis Gold rating and published a comprehensive sustainability report covering initiatives across the organisation. It has also been recognised as a 2026 Avtar & Seramount ‘Best Company for ESG’, acknowledging its commitment to responsible business, transparency and accountability.

The direction, Gandhi said, is to recover more from every tyre, improve material quality and create additional applications for those recovered materials.

GAINING GROUND

Interest in recycled and renewable materials is increasing, although Gandhi said recycled content varies significantly depending on the material, application and performance requirements.

For reclaim rubber, she cited Rubber Board data showing domestic consumption of almost 167,500 tonnes in 2024-25, including about 67,000 tonnes consumed by automotive tyre manufacturers.

GRP supplies reclaim rubber to major tyre manufacturers globally, Gandhi said, adding that eight of the world’s top 10 tyre manufacturers are its customers.

She noted that recyclers and tyre companies need to work together from the product-development stage, developing materials and testing capabilities for specific applications and establishing appropriate quality and performance parameters.

Sustainability targets will translate into meaningful virgin-material substitution only when recycled alternatives meet requirements around quality, safety, consistency and economics, she added.

Despite India’s sizeable tyre-recycling ecosystem, Gandhi said a significant proportion of the industry continues to serve relatively lower-value applications.

“The next opportunity is to retain more of the material value contained within an end-of-life tyre by developing markets for high-quality reclaim rubber, recovered carbon black, pyrolysis products and engineered tyre-derived materials,” she noted.

Achieving that transition will require recyclers and downstream industries to collaborate on qualification, testing and application development.

Gandhi also argued that comparisons between virgin and recycled materials should move beyond price.

“Cost needs to be considered alongside performance, consistency, carbon footprint and supply security. Recyclers, meanwhile, will need to invest in process control, research and development and testing to improve performance, while scale, automation and energy efficiency will be critical to improving costs,” she contended.

NEXT PHASE

Greater standardisation and quality benchmarks will be among the most important enablers of the industry’s next stage, Gandhi said.

Tyre manufacturers and other industrial customers need confidence that recycled material purchased today will meet the same critical parameters when supplied months later.

This places increasing importance on testing protocols, traceability and credible certification.

Gandhi said standards should nevertheless avoid becoming barriers to innovation. Instead, they should be performance-based, allowing new technologies and materials to develop while providing customers with confidence around consistency and safety.

She sees MRAI as potentially playing a constructive role by bringing recyclers, tyre manufacturers, standards bodies, technical institutions and policymakers together.

GRP’s immediate priorities include scaling its next-generation reclaim-rubber business, ramping up the Pyrova Energy platform, commissioning recovered carbon black capacity and investing further in innovation and research and development to develop higher-value products and applications.

But Gandhi said her ambitions extend beyond the company.

Through her role with the Women in Recycling Committee, she wants to increase women’s participation particularly in leadership, technology and technical functions.

“The next generation of women in recycling should not just be entering the industry but shaping its technology, factories, businesses and future,” contended Gandhi.

Her message to young and aspiring women was not to make themselves smaller to fit the room but to prepare well, do the work, speak up and take their place.

That objective intersects with Gandhi’s broader view of where the Indian recycling industry is heading.

“India has an opportunity to progress from waste management towards resource recovery and sustainable-material manufacturing. Combining stronger regulation and standards with responsible manufacturing could help develop a globally competitive circular-materials industry,” she said.

For women entering the sector, that transformation could simultaneously broaden the types of careers available.

As recycling becomes more technical, formalised and closely integrated with manufacturing, Gandhi believes the new generation’s familiarity with sustainability and circularity could help accelerate that shift.
