The Tire Industry Project (TIP) has announced the publication of a scientific study presenting a sophisticated model designed to track how tyre and road wear particles (TRWP) move through land and freshwater environments. Known as the Mass Balance Model, this tool provides a method for predicting particle concentrations within watersheds across different climates and regions, offering high spatial detail on how these particles travel from roadways towards rivers, lakes and estuaries.

Tyre and road wear particles are created unintentionally during normal driving, where tyres meet the road surface. As scientific and regulatory focus on these particles intensifies, reliable models are essential for understanding their environmental pathways. While research is growing, the behaviour of these particles in waterways remains particularly understudied, making this modelling advance especially relevant.

The model draws on global and local datasets and open-source frameworks, including the ERA5 global climate dataset by the Copernicus Climate Change Service and the Wflow catchment hydrology model by Deltares, a research institute. Its accuracy has been confirmed using field measurements from the Seine River basin in France, the Chesapeake Bay basin in the United States and the Yodo River basin in Japan – three very different watersheds. This validation shows the approach works across diverse watershed sizes, climates and stormwater management systems.

Applying the model to these three regions revealed that the share of particles reaching surface waters varies from just 2 percent up to 18 percent, depending on urbanisation, climate, basin size and drainage infrastructure. Importantly, improvements to stormwater systems could cut particle transport to surface waters by as much as half. This refined model builds on earlier work and is now globally applicable, with ongoing development aimed at making it accessible beyond the scientific community.

Nicolas Tissier, Director of Research at TIP, said, “Having a robust, reproducible model for TRWP transport and fate that can be applied worldwide is essential for advancing both scientific understanding and practical solutions. Our role at TIP is to support rigorous, transparent science that helps researchers, policymakers and industry make evidence-based decisions. By making this model open access, we aim to support broader collaboration across the scientific community around TRWP in the environment and to enable the development of more effective mitigation strategies.”

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.

Zeon has been recognised as a Supplier Engagement Leader in the 2025 Supplier Engagement Assessment (SEA) conducted by CDP, a United Kingdom-based international environmental nonprofit organisation. This achievement represents the first time the company has received the highest possible rating in this assessment.

The evaluation measures how corporations address climate change within their supply chains, focusing on responses to the CDP Climate Change Questionnaire across five critical areas. These include governance, emissions targets, Scope 3 emissions management, risk management and overall supplier engagement strategies.

Zeon earned the top rating for its efforts to reduce greenhouse gas emissions through supplier collaboration, a group-wide initiative, alongside continuous dialogue maintained via procurement activities. Guided by its philosophy of contributing to planetary preservation and human prosperity, Zeon remains committed to sustainable management. The company reaffirmed that it will continue working with suppliers and other stakeholders to tackle climate change and meet societal expectations.

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."
