A car made from recycled plastic? This could be the future

What comes around goes around: Your discarded plastic water bottle may soon become part of your next car.

Automakers are racing to make their vehicles more sustainable -- the industry's favorite buzzword -- by turning environmentally unfriendly materials into seat cushions, floors, door panels and dashboard trims. First it was reclaimed wood. Then "vegan" leather. Now, plastic waste from the ocean, rice hulls, flaxseeds and agave are transforming the manufacturing process.

"Everyone is awakening to the problems of plastic and waste," Deborah Mielewski, a technical fellow of sustainability at Ford, told ABC News.

Ford in particular has been championing the use of renewable materials in its vehicles. In 2008 it replaced the petroleum-based polyol foam in its Mustang sports car with seat cushions made from soy, an industry first. More recently Mielewski and her team started examining how to transform some of the 13 million metric tons of ocean plastic, which threaten marine life and pollute shorelines, into parts for future Ford vehicles. The result? Wiring harness clips in the new Ford Bronco Sport that were once nylon fishing nets.
