The Yokohama Rubber Co., Ltd., has begun practical testing of its Tyre air Pressure Remote access System (TPRS) as a tyre solution service for taxi companies. The company said in a statement that the testing began in May and has been conducted with its tyre sales subsidiary Yokohama Tire Japan Co., Ltd., and with the cooperation of Kyoto Taxi Co., Ltd., and Koshin Taxi Co. 

The TPRS test is being conducted using tyre air-pressure sensors developed by Yokohama Rubber attached to the inner surface of tyres mounted on taxis operated by the two companies in Kyoto Prefecture and surrounding areas. 

The testing seeks to verify the effect of TPRS and the air pressure sensors attached to tyres’ inner surface, which Yokohama Rubber has developed as part of its response to changes in the automobile industry, such as CASE and MaaS. 

TPRS and the air-pressure sensors attached to tyres’ inner surfaces enable car fleet operators and Yokohama Rubber service staff to remotely monitor tyre air pressure, temperature, and vehicle location. The system greatly reduces time spent checking tires at the start of each day and records air-pressure data. It enables early detection of slow punctures that cause gradual air leakage. It also contributes to proper tyre maintenance, helps prevent inspection irregularities, and improves fuel efficiency by maintaining proper air pressure. 

In addition, the system’s ability to detect tyre abnormalities in real time can help prevent accidents. Detection data is transmitted to a cloud server, enabling the taxi company’s fleet managers and Yokohama Rubber’s sales offices to monitor tyre air pressure. An alarm device installed in the taxi operator’s office will notify the fleet manager when air pressure falls to a level that will reduce fuel efficiency or indicates a possible slow puncture. 

Unlike the conventional valve-type TPMS (Tyre Pressure Monitoring System), air-pressure sensor attached to tyres’ inner surface can be used on a wide variety of vehicles and wheels as an aftermarket part that can be used with any wheel type. 

Yokohama Rubber previously has conducted practical testing of its TPRS for corporate cars and car-sharing companies, but the current test being conducted with taxi companies that require strict tyre management is aimed at establishing a business model that contributes to the improved safety and economical operation of taxi fleets, it added.

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."
