Alessio Iacovelli Named Deputy Director Replacement Sales West Europe At Linglong Tire
- By TT News
- October 10, 2025

Linglong Tire has announced the promotion of Alessio Iacovelli to Deputy Director of Replacement Sales for Western Europe, effective 1 September 2025. In this elevated role, Iacovelli will take on leadership of the regional sales team with a mandate to accelerate business development. His key objectives will include forging strategic alliances and implementing programmes to strengthen customer loyalty. Iacovelli will report directly to Lisa Zhao, the Director of Replacement Sales for Western Europe, and will collaborate with her to manage key markets, including Germany, the UK, Italy and Spain.
Iacovelli, who began his career with Goodyear and Nexen, first joined Linglong Tire at the end of 2022 as a Sales Manager. In that capacity, he demonstrated significant success in developing the Southern European aftermarket, where he expanded the brand's footprint, defined effective growth strategies and secured robust partnerships with distributors. This strategic appointment and the restructuring of the sales leadership underscore Linglong Tire's intensified focus on achieving its ambitious growth targets across the European continent.
Iacovelli said, "I am very pleased to have been promoted to Deputy Director Replacement Sales West Europe at Linglong Tire. We have fantastic products such as the Sport Master 4S and the Sport Master Winter, both successfully tested in the recently published tyre tests. We have a state-of-the-art development centre in Germany and a new tyre plant in Europe and are successful in original equipment – ideal conditions for achieving our ambitious goals together with my team and the colleagues in Hannover and continuing to grow, especially in Europe."
ARLANXEO To Close French Plant As Chemicals Sector Struggles
- By TT News
- October 10, 2025

German synthetic rubber maker ARLANXEO has launched consultations with worker representatives over the potential closure of its Port Jerome facility in France, citing persistent weak demand and declining competitiveness in the European chemicals industry.
The company, which is majority-owned by Saudi Aramco, had begun an information and consultation period with the Works Council at the site, located in northern France. A final decision on the closure will be taken after the mandatory consultation process concludes and approval is obtained from the French labour authorities, DREETS.
“The European chemical industry continues to face persistent weak demand and declining competitiveness driven by rising costs, unbalanced global markets, and increased regulatory pressure,” said Stephan van Santbrink, ARLANXEO chief executive.
“These conditions have generated a significant burden on the sector across the regional value chain. ARLANXEO has not been an exception to these challenges. The Port Jerome site has remained in a structurally loss-making position. Despite numerous improvement efforts, we do not foresee a viable path to a sustained structural improvement.”
The company did not disclose how many jobs would be affected by a potential closure, nor did it provide details on the facility’s production capacity or annual output.
Van Santbrink acknowledged the impact on workers, saying: “We recognise the impact a potential closure may have on our employees, and we regret the need to consider these steps. We will continue to treat all employees with respect. If we decide to cease operations at the site, we will do our utmost to assist in finding alternative solutions for all impacted employees. In addition, we intend to provide impacted employees with a social plan which reflects their valued contribution to ARLANXEO.”
The announcement adds to a growing list of European chemical producers struggling with high energy costs, sluggish demand and competition from lower-cost producers in Asia and the United States.
ARLANXEO said it would work closely with all affected internal and external stakeholders to minimise the impact of the intended closure.
Continental Appoints Managers For Global Purchasing And Original Equipment Business
- By TT News
- October 07, 2025

Continental's Tires group sector has strengthened its leadership team with two key internal appointments, effective 1 September 2025. Jana Striezel has been named the new head of global purchasing for Continental Tires, while Dennis Bellmund has assumed leadership of the global original equipment business for both passenger and commercial vehicles. Both executives will report directly to Christian Kötz, the member of Continental AG's Executive Board who leads the Tires group sector.
In her new capacity, Striezel will oversee worldwide strategic and operational purchasing. She brings extensive experience from the automotive industry, having previously held several procurement management roles at Renault, where she led purchasing for the Renault brand and its alliance with Nissan and Mitsubishi in Europe. Her career began at Volkswagen in 2014.
Bellmund, who has a 25-year tenure with Continental, steps into his role following the departure of his predecessor, Manja Greimeier, to the ContiTech sector. His extensive background within the company includes recent responsibility for Continental’s tyre retail operations, alongside prior leadership roles in EMEA supply chain management and sales direction for the European replacement tyre business. These appointments signal a strategic reinforcement of Continental's tyre division leadership.
Kötz said, “We’re delighted to welcome Jana Striezel, a highly skilled manager, to our team. She brings extensive expertise in international procurement and will focus on driving forward our purchasing strategy. In Dennis Bellmund, our global original equipment business has gained a highly experienced leader. Thanks to his many years at Continental, he is familiar with our company and our customers’ needs from many different angles. On behalf of the entire management team, I wish both of them every success in their new roles and look forward to working together.”
“On behalf of the entire team, I would like to thank Manja Greimeier for her successful leadership of our original equipment business and wish her all the best and continued success,” added Kötz.

In a significant leadership update, LD Carbon (LDC) has announced a restructuring of the chief executive office at the company. The company confirmed that Seong-Moon Baek will now serve as the sole CEO. This move follows the departure of former co-CEO Yong-Kyung Hwang from the executive position.
The change is effective immediately as the company continues to advance its initiatives in the sustainable materials sector. Chief Commercial Officer Bumseek Kim (BK) formally communicated the development in a statement, saying, “Should you have any questions, please feel free to contact me at any time.”
