What is the connection between black and green tyres and green environmental protection? First of all, it is related to fuel consumption. As Chen Zhihong, president of the Rubber Branch of the China Rubber Association, said, “Many people do not know how much the rolling resistance of the tires will affect the fuel consumption.†Green tires with special materials and tread design can reduce rolling resistance by more than 20%. Wearing green running shoes can reduce energy consumption by more than 5%.
Bridgestone, who is the chief of the rubber and tire industry, knows the significance of this. Wu Tianbang, President of Bridgestone Tire Co., China, said: “The tire industry has a practice of dividing brands based on their basic performance. Bridgestone is making environmental protection the common gene of the brand and a separate axis in the brand's coordinate system.â€
This can be seen as Bridgestone's internalization of past environmental protection efforts into a brand connotation. As early as in 1991, Bridgestone launched a green tire code-named EV-01 for electric vehicles. Three years later, the brand was officially named ECOPIA. After nearly 20 years of upgrading and covering cars, trucks and buses, , officially landed in China in March 2010.
ECOPIA, in front of environmental protection (Ecology), followed by Utopia, Chinese translation "green song partner", which means "green care is like a warm song, with you along the way." This beautiful name has a double meaning for Bridgestone. It is not only an independent brand, but also a green "gene" shared by the brand. ECOPIA brand's products, in addition to the characteristics of environmental protection, but also in their own sports, comfort, off-road and other basic performance on the focus.
According to the statistics of the Japan Automobile Transportation Technical Association, ECOPIAEP100A can improve fuel efficiency by 6.2% compared to general comfort tires.
Compared to ordinary tires, tires marked with ECOPIA have essential differences. The "ECOPIA compound" formed by the special modified polymer and carbonized combination of Polysulfide is filled in the gap between the styrene-butadiene rubber molecules of the tread rubber and lubricates the friction between the rubber molecules, thereby reducing fuel consumption and controlling the exhaust gas of automobiles. Emissions. In addition, the optimized design of the cross-sectional shape ensures that the rigidity is optimized to reduce the rolling resistance; while the longitudinal reinforcing ribs achieve the uniform ground pressure to increase the friction coefficient and improve the braking performance.
In addition to safety advantages based on energy saving, tires can also reflect their green elements through durability. The softer-use ECOPIAEP100 has been launched in Japan in 2008. However, since the length of China’s national highway is more than 25 times Japan’s, the actual speed of the highway is higher than that of Japan’s 80km/h. In winter, the temperature difference between Heilongjiang and Hainan can reach 60-70 degrees Celsius. Therefore, the first thing Bridgestone needs to consider is to ensure environmental protection technology with safety and comfort. For this reason, the prudent measures such as technology research and development, trial production, and market use testing for China's use conditions are very time-consuming. The green song companion EP100A that entered China can be described as a sword in 3 years, which greatly improved the durability of the tire.
Extraordinary efforts have paid off. Takeda Takemoto said that since the launch of the green song with the EP100A in May, the market has responded so well that the production capacity of the Wuxi plant has not been able to keep up. "We plan to further expand production in August."
In all stages of the tire life cycle, the carbon dioxide emissions generated during the use phase accounted for 87%, and Bridgestone has not spared energy saving and emission reduction in other sectors. Always pursuing the highest quality contribution to society, Bridgestone is a company policy and always regards “environmental protection†as one of the important issues for corporate business activities, and implements advanced environmental protection concepts in management, production, sales, and research and development. From the end of 2009, after reaching a landfill rate of 0.5% or less, Bridgestone's four factories in China achieved zero emissions in June 2010.
