Yokohama Rubber Company announced today that, together with the Surat Thani branch of the Rubber Authority of Thailand (RAOT), it held a seminar event in December in order to help Thai natural rubber farmers improve the quality and productivity of their natural rubber. Fifty farm households in the Surat Thani area participated in the event. Yokohama claims that each participating household received a complimentary 250 kg of fertiliser developed using RAOT’s specialist knowledge. The seminar is the fourth held by Yokohama Rubber and RAOT since 2020.

Yokohama states that it signed a Memorandum of Understanding (MoU) with the RAOT in January 2020 in order to cooperate in efforts to provide economic support for Thai natural rubber farmers and to improve traceability to ensure transparency and soundness of the natural rubber supply chain. The MoU and events held under it are concrete actions based on Yokohama’s ‘Procurement Policy for Sustainable Natural Rubber’. According to Yokohama, the farmers who received fertiliser at this event are cooperating in follow-up surveys on its effect on the physical properties and productivity of their natural rubber. Another action under the MoU is a program of onsite surveys that began in 2019 that seeks to analyse the issues faced by natural rubber farmers in Surat Thani area, home to Yokohama Rubber’s Thai natural rubber processing company, YT Rubber Co., Ltd.

A founding member of the Global Platform for Sustainable Natural Rubber (GPSNR), Yokohama claims that it revised its ‘Procurement Policy for Sustainable Natural Rubber’ in September 2021 and is strengthening its collaboration with GPSNR activities. The recent seminar event in Thailand reflects the principle of ‘Support for suppliers, including small-scale farmers and other parties involved in the supply chain’ set forth in the procurement policy. As per Yokohama, the tyre company will continue to implement and announce initiatives in line with the action guidelines stipulated in this policy. The company is also endeavoring to achieve the Sustainable Development Goals (SDGs) adopted by the United Nations. Yokohama states that as part of these efforts, the Yokohama Rubber Group is promoting the procurement of sustainable raw materials. Also, this December, the tyre company signed an MoU with an Indonesian natural rubber supplier. Yokohama claims that the two companies held a seminar event for small-scale natural rubber farmers in Indonesia.

The sustainability initiatives included in Yokohama Transformation 2023 (YX2023), Yokohama Rubber’s medium-term management plan for fiscal years 2021–2023, are based on the concept of ‘Caring for the Future.’ By implementing sustainability initiatives under this concept, Yokohama Rubber is endeavoring to help resolve social issues through its business activities, states the tyre company.

Tegeta Green Planet and Shine Energy, both affiliated with Tegeta Holding, have launched a joint educational initiative to raise environmental awareness and a sense of responsibility among young people. The project addresses modern challenges such as environmental protection and sustainable development.

Company representatives are visiting schools across Tbilisi to hold informational meetings, presentations and workshops. The programme begins with presentations, followed by interactive games and activities designed to help students retain the information. At the end of each session, participants receive symbolic gifts and prizes as motivation.

Tegeta Green Planet focuses on teaching students the principles of specific waste management, including how to properly handle used tyres, batteries and oils. The sessions explain why proper waste management is essential for environmental protection and how it connects to the circular economy. Meanwhile, Shine Energy educates young people on the importance of energy, its everyday use and why developing renewable and sustainable energy resources is crucial.

The initiative is not limited to schools. In the near future, both organisations will expand their efforts to universities, aiming to broaden awareness about environmental protection, waste management and energy efficiency. The ultimate goal is to foster environmentally responsible attitudes among the younger generation, helping build a more sustainable and conscious society.

German chemical group WACKER has announced a price increase of up to 15 percent for its resins, dispersions and dispersible polymer powders produced at its European and US facilities. The adjustment takes effect on 1 June 2026, or as existing customer contracts permit. The move is designed to allow the company’s Polymers division to maintain high product quality, deliver technological innovations and provide superior customer service and technical support. It will also support investments aimed at securing future growth in key markets.

Rising costs for raw materials and logistics have forced the pricing measure, with the Polymers division being particularly affected. The recent conflict in the Middle East has caused significant disruptions across global commodity markets. As a direct result, prices for energy, raw materials and transportation have climbed sharply.

Despite the increase, WACKER remains focused on sustaining its commitment to customer support and long-term capability. The company underscored that the adjustment is necessary to continue meeting market demands while ensuring operational stability and future-oriented development across its focus markets.

Pirelli North America has launched its first closed-loop circular recycling initiative, marking a significant step in the company’s broader strategy to increase recycled and bio‑based content in its tyre production. The project has received the Tire Recycling Foundation’s Value Chain Collaboration Award.

The programme recovers scrap tyres generated during Pirelli’s own North American manufacturing process. These materials are sent to Bolder Industries, which applies ISCC PLUS‑certified pyrolysis technology to produce BolderBlack recovered carbon black. Pirelli then reintroduces this material into new tyre production at its North American facilities, partially replacing virgin carbon black. The effort is part of a wider Pirelli plan to expand such industrial ecosystems across the group’s production network, aiming to valorise waste by reintegrating recovered materials into tyre manufacturing.

Beyond the award, the initiative reflects Pirelli’s broader circularity approach, which includes ongoing work to boost recycled and bio‑based material usage. The company targets over 80 percent bio‑based and recycled content in its best‑performing products and forty percent in total production by 2030.

Claudio Zanardo, CEO, Pirelli North America, said, "The Rome plant is one of the most technologically advanced manufacturing facilities in Pirelli. This initiative reflects an approach focused on increasing the use of recovered materials within existing production processes. It is part of a broader effort to gradually integrate raw materials derived from recycled resources into our products while maintaining consistency in performance and quality."

Tony Wibbeler, CEO, Bolder Industries, said, "Our collaboration demonstrates that a traceable, mass-balance approach to tyre-to-tyre circularity is not only achievable, but it's ready to scale inside a premium manufacturing environment, meeting real performance and certification requirements at every step. This is the kind of progress the industry has been working toward for many years."
