Oil-soaked plastic boom material used to soak up oil in the Gulf of Mexico is finding new life as auto parts in the Chevrolet Volt. General Motors has developed a method to convert 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. "We reuse and recycle material by-products at our 76 landfill-free facilities every day. This is a good example of using this expertise and applying it to a greater magnitude."
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 comprised of 25% boom material and 25% 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 massive high-speed drum that spun the booms until dry and eliminated 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 Enduraprene material process to combine the resin with other plastic compounds to produce the components.
The Chevy Volt was recently awarded Green Car of the Year by Green Car Journal.
GM recycles materials at every state of the product lifecycle. It uses recycled and renewable materials in its cars and trucks, which are at least 85% recyclable. Used tires, old plastic bottles, denim and nylon carpet are all redirected from landfills and reused in select GM vehicles.
GM facilities worldwide recycle 90% of the waste they generate. The automaker recently announced more than half of its worldwide facilities are now landfill-free all manufacturing waste is recycled or used to create energy.
