Continental is increasing its use of recycled materials in tyre manufacturing, with more facilities now using polyester fabric made from recycled polyethylene terephthalate (PET) bottles. This initiative has raised the recycled content in several tyre lines by an average of thee percent. Depending on the tyre size, up to 15 PET bottles can be used in a single tyre, conserving valuable resources.

“Reduce, reuse, recycle – this trio is key to more sustainable tyres “, says Jorge Almeida, Head of Sustainability at Continental Tires.

“Reduce, reuse, recycle – this trio is key to more sustainable tyres. Wherever possible, we use recycled materials while maintaining our highest quality standards,” says Jorge Almeida, Head of Sustainability at Continental Tires. “Our polyester yarn made from recycled PET bottles is just as strong as conventional polyester yarn. This shows that sustainability, performance, and safety go hand in hand at Continental.

The company’s ContiRe.Tex technology, unveiled in late 2021, processes PET bottles that would otherwise go unrecycled. These bottles are spun into high-performance polyester yarn without intermediate chemical treatments, producing materials robust enough to meet the demands of tyre manufacturing.

Since 2022, this technology has been used on a limited scale at Continental’s tyre plants in Lousado, Portugal, and Otrokovice, Czech Republic. Recently, facilities in Korbach, Germany, and Sarreguemines, France, have also adopted recycled PET in series production.

Ambitious sustainability goals

The transition to sustainable materials aligns with Continental’s broader sustainability strategy. The company aims to increase the proportion of renewable and recycled materials in its tyres to over 40% by 2030. By then, all new car and light truck tyres are expected to feature high-performance polyester fibres made entirely from sustainable PET.

At present, an average passenger tyre contains 15–20 percent recycled and renewable materials. By 2050, Continental plans for all its new tyres to be made from 100 percent sustainable materials.

Turning waste into high-quality materials

Continental’s use of recycled PET is part of a broader effort to replace raw materials with sustainable alternatives. Textile fabrics made from recycled polyester enhance the strength, flexibility, and durability of tyres, with performance matching that of materials derived from crude oil.

In addition to recycled PET, Continental is exploring other sustainable materials, including bio-based and chemically recycled PET. Agricultural by-products, such as rice husk ash, rubber from dandelions and recycled rubber, are also being tested for future use.

LD Carbon, a South Korean environmental materials company, has filed a criminal complaint against its former chief executive and two senior finance officials, accusing them of embezzling corporate funds and misusing government subsidies through falsified payments and internal approvals.

The filing, submitted to the Suseo Police Station in Seoul and accessed by Tyre Trends magazine, names former CEO Hwang yong-kyung (YK), Chief Financial Officer Lee Chung-jin and Finance Manager Han Seung-yeon (Sara) as suspects in an alleged scheme that spanned from 2022 to 2023. 

At the centre of the complaint is what the company describes as a ‘bonus recycling’ scheme designed to create off-the-books cash. Following the complaint, a probe has been initiated. 

After LD Carbon raised about KRW 18.5 billion (approximately USD 12.5 million) in Series A funding in 2022, Hwang allegedly instructed selected employees to accept inflated bonuses or salary payments and return portions of the money in cash. 

The approach, according to the filing, was framed as a way to manage tax exposure while enabling payments that could not be processed through formal corporate channels.

Internal documents cited in the complaint show unusually large bonus allocations in the tune of tens of millions of won per employee, which is far exceeding typical compensation levels. 

The payments were approved through standard company processes with sign-offs from the finance department including the CFO, the filing states.

The complaint includes call recordings and internal communications in which employees were allegedly directed to return funds as well as bank transaction records showing the movement of money through employee accounts.

Broker fee dispute tied to fundraising
The company alleges that part of the diverted funds was used to pay a broker commission linked to the 2022 fundraising round.

According to the filing, a third-party intermediary involved in introducing investors was promised a success fee of roughly 2.5 percent of total funds raised, equivalent to about 137.5 million won. 

While the individuals allegedly agreed to cover the fee personally, the complaint claims the payment was instead funded using company money routed through the bonus scheme.

Messages cited in the complaint suggest internal discussions about dividing the fee among executives, indicating awareness that the expense was not a legitimate corporate liability.

Government subsidies allegedly misused
Beyond corporate funds, the complaint accuses the executives of improperly using government subsidies provided for environmental export and development projects.

LD Carbon participated in programmes administered by state-affiliated agencies to support overseas expansion of eco-friendly businesses. Under South Korean law, such subsidies must be used strictly for designated purposes.

The filing alleges that funds were instead diverted to unrelated expenses, including payments to affiliated or controlled businesses, costs for unrelated products such as golf balls and consumer goods and marketing and vendor payments supported by fabricated invoices.

Supporting materials include internal approval documents, emails and supplier invoices, which the company claims were falsified to justify the expenditures.

Potential legal violations
The allegations, if substantiated, could constitute multiple criminal offences under South Korean law, including occupational embezzlement, criminal breach of trust and violation of the Subsidy Management Act.

Under applicable statutes, misuse of government subsidies can carry penalties of up to five years in prison or significant fines with additional exposure under broader financial crime provisions.

The complaint alleges that the three individuals acted in collusion, emphasising how their roles complemented one another within the organisation’s financial structure. It points to Hwang, in his capacity as CEO, as having overarching authority and control over the organisation’s funds, thereby setting the strategic and operational direction.

It further highlights Lee’s position as CFO, noting his responsibility for financial oversight, governance and ensuring the integrity of financial management processes. Within this framework, Lee is portrayed as a key figure in monitoring and validating the movement and use of funds.

Finally, the complaint identifies Han, the finance manager, as the individual responsible for executing transactions. In this role, Han is described as operationalising financial decisions, thereby completing the chain of actions that, according to the complaint, demonstrates coordinated conduct among all three parties.

Internal disruptions 
Separate company records reviewed indicate that multiple employees resigned during and after the period in question. While there is no confirmed causal link between these departures and the alleged misconduct, the timing has drawn attention. 

Some employees named in the complaint appear to have been involved in processing or receiving the disputed payments, suggesting that certain staff members may have acted as intermediaries, knowingly or otherwise, within the alleged scheme.

At present, the matter remains at the complaint stage and it is unclear whether authorities have formally initiated a criminal investigation or undertaken actions such as issuing summons or conducting searches. 

Also. Korea Environmental Industry and Technology Institute (KEITI) conducted audit on LD Carbon on 24 April 2026, which will soon to be followed with further investigation and preliminary disposition if wrong use of govt fund is confirmed.

The case underscores growing regulatory and public scrutiny over how companies manage government-backed funding alongside private investment in South Korea’s innovation-driven economy. 

In recent years, regulators have intensified oversight, particularly in sectors linked to sustainability and advanced manufacturing. The outcome of the case may ultimately hinge on how authorities interpret the intent behind the transactions and whether internal approval mechanisms are found to have concealed or facilitated the alleged misuse of funds.

Michelin reported lower first-quarter revenue after adverse currency movements offset stable underlying sales, while the tyre maker maintained its 2026 guidance amid growing geopolitical and supply chain uncertainty.

Group revenue for the three months to 31March fell 5.4 percent year on year to €6.2bn, compared with €6.5bn a year earlier. Michelin said the decline was entirely due to currency effects, primarily the appreciation of the euro against the US dollar and several other currencies. At constant exchange rates, revenue was stable.

Tire volumes declined 1.4 percent during the quarter, although replacement sales improved, supported by a 3 percent increase in MICHELIN-brand tire volumes. A favourable product mix, particularly in larger premium tires, partly offset weaker original equipment demand.

The Consumer segment recorded revenue of €3.4bn, down 4.4 percent on a reported basis. Michelin said replacement sales of passenger car and light truck tires remained resilient, while original equipment sales continued to be affected by weaker automotive markets, particularly in China. Sales of 18-inch and larger tires represented 69 percent of MICHELIN-brand sales during the quarter.

Revenue in the Transportation segment fell 11.3 percent to €1.4bn, reflecting weaker original equipment demand in North and South America and adverse exchange rates. Replacement sales increased in Europe but remained subdued in North America amid a softer road freight market.

The Specialties segment reported revenue of €1.1bn, down 3.3 percent. Michelin said mining and aircraft tire sales increased during the quarter, while beyond-road activities stabilised despite continued weakness in agricultural original equipment markets.

Polymer Composite Solutions revenue rose 5.1 percent to €326m, supported by the integration of Cooley Group and growth in sealing and coated fabric activities. Michelin said the segment would continue expanding through the integration of Flexitallic in April and the expected consolidation of TexTech later in 2026.

The company said uncertainty linked to the Middle East conflict continued to create risks around global demand, raw material supply and energy costs. Michelin nevertheless maintained its financial outlook for 2026, citing operational resilience, localised production and supply chain integration.

During the quarter, Michelin also completed the acquisitions of Cooley Group and Flexitallic as part of efforts to accelerate the growth of its Polymer Composite Solutions business.

Hankook Tire, the exclusive tyre supplier for the FIA World Rally Championship, has concluded the fifth round of the 2026 season, Rally Islas Canarias, which took place from 23 to 26 April in Spain’s Canary Islands. For the demanding asphalt stages, Hankook provided its specialised Ventus Z215 and Ventus Z210 tarmac rally tyres, engineered to handle extreme conditions.

The event, first held in 1977, marked its 50th anniversary this year and its second edition as an official WRC round. Competitors tackled 18 special stages across Gran Canaria Island, centred around Las Palmas, covering approximately 322.61 kilometres. The course featured rough, high-abrasion volcanic asphalt with dramatic elevation changes, while dense fog and local rain above 1,000 metres made weather a decisive factor. The opening day’s Super Special Stage at the BP Ultimate Circuito Islas Canarias offered side-by-side racing, where small pace differences quickly altered positions.

Hankook’s tyres provided reliable grip and control at high speeds and through continuous cornering, helping drivers maintain stability on the technical routes. Sébastien Ogier of TOYOTA GAZOO Racing secured his first win of the season, leading a team podium sweep. In the Drivers’ Championship, Elfyn Evans leads with 101 points, followed closely by Takamoto Katsuta on 99.

The 2026 WRC season now moves to Round 6, Vodafone Rally de Portugal, from 7 to 10 May in northern Portugal, a demanding event mostly on unpaved surfaces. Hankook will operate a ‘Brand World’ booth in the service park there, using motorsport content and hands-on experiences to promote its premium image. As exclusive WRC tyre supplier since 2025, Hankook continues integrating data from over 70 global championships into R&D, advancing high-performance tyre technology and the Ventus brand’s global leadership.

wdk, the German Rubber Industry Association, and the ADK, the German Rubber Industry Employers’ Association, hosted their annual Rubber Industry Day in Berlin on 28 April 2026. The event saw wdk President Michael Klein issue an urgent call for industrial policy measures, warning that pressure on Germany’s manufacturing base remains relentless. He argued that the country can no longer afford strategic delays, insisting that declarations of intent must be replaced by immediate action to reduce bureaucracy and energy costs for businesses.

Citing fresh member survey data, Klein reported that sales, revenue and production levels in Germany’s rubber industry are predominantly declining compared to the previous year. He described this downturn as a clear warning signal, noting that companies have exhausted their potential at domestic sites. Without political support, he added, only foreign markets remain viable alternatives, while Germany continues to lose industrial substance.

The wdk president stressed that the federal government’s failure to implement countermeasures risks permanent damage to the nation’s industrial base. He expressed bafflement that political decision-makers have long known what needs to be done yet have failed to act for an extended period. Klein concluded that proactive intervention is now essential, as the erosion of Germany as a production location must finally be stopped to preserve the manufacturing sector as the backbone of the economy and a guarantor of prosperity.
