Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. Automobile tire rubber in general consists of approximately 40?

New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water. —Yong Wang.
