Chevy Volt Components Created from Gulf of Mexico OilSoaked Booms

Oil-soaked plastic boom material used to soak up oil in the Gulf of Mexico is finding new life in auto parts for the Chevrolet Volt.

Oil-soaked plastic boom material used to soak up oil in the Gulf of Mexico is finding new life in auto parts for the Chevrolet Volt.

General Motors has developed a method to reuse an estimated 100 miles of the material off the Alabama and Louisiana coasts and keep it out of the nation's landfills. The ongoing project is expected to create enough plastic under hood parts to supply the first year production of the extended-range electric vehicle.

"Creative recycling is one extension of GM's overall strategy to reduce its environmental impact," said Mike Robinson, GM vice president of Environment, Energy, and Safety policy.

Recycling the booms will result in the production of more than 100,000 pounds of plastic resin for the vehicle components, eliminating an equal amount of waste that would otherwise have been incinerated or sent to landfills.

The parts, which deflect air around the vehicle's radiator, are made of 25 percent boom material and 25 percent recycled tires from GM's Milford Proving Ground vehicle test facility. The remaining is a mixture of post-consumer recycled plastics and other polymers.

GM worked with several partners throughout the recovery and development processes. Heritage Environmental managed the collection of boom material along the Louisiana coast. Mobile Fluid Recovery stepped in next, using a large, high-speed drum that spun the booms until they were completely dry, eliminating all the absorbed oil and wastewater. Lucent Polymers used its process to then manipulate the material into the physical state necessary for plastic die-mold production. Tier-one supplier GDC Inc. used its patented Endurapreneā„¢ material process to combine the resin with other plastic compounds to produce the components.

The work in the Gulf is expected to last at least two more months, and GM will continue to assist suppliers in collecting booms until the need no longer exists. The automaker anticipates enough material will be gathered that it can be used as components in other Chevrolet models.

"This was purely a matter of helping out," said John Bradburn, manager of GM's waste-reduction efforts. "If sent to a landfill, these materials would have taken hundreds of years to begin to break down, and we didn't want to see the spill further impact the environment. We knew we could identify a beneficial reuse of this material given our experience."
