DETROIT, Michigan — Survey the latest at the Detroit Auto Show and you will find fibers from water bottles in car seats, hemp in the dashboards and citrus peel in the tires. Automakers, in a continuing quest to develop lighter and more environmentally friendly vehicles, are making increased use of sometimes unlikely materials in their cars and trucks.
U.S. auto giant Ford has set a requirement that the seat fabrics sold on all vehicles in North America must have at least 30 percent recycled content, said Barb Whalen, Ford’s color, material and design manager.
There will be no relaxation of this rule due to low crude-oil prices, which have made petroleum-based components cheaper, she said.
“It’s the right thing to do, for the environment, for ourselves and our customers,” Whalen told AFP. “Even though oil prices are cheaper, it’s still the best thing.” Automakers are also using more plant-based items, such as eucalyptus fibers, which are going into dashboards of the BMW i3, a plug-in hybrid. Faurecia, a French automotive parts supplier, sees growth in its “bio” business, even if it remains small, said Pierre Demortain, a sales executive in the joint venture Faurecia APM, which specializes in those materials. Natural materials tend to be lighter than synthetic ones, he said.
“Hemp is a plant that doesn’t need irrigation or pesticides to grow and can reduce door weight by 25 percent,” he said. Faurecia currently combines hemp with petroleum raw materials as a component in its plastics. But in two or three years, the plastics are expected to be 100 percent natural-based, Demortain said.
