Just the Facts Recycling Automotive Parts Lifecycle Assessment Case Studies

The vehicle that you are driving today will be a source of numerous recyclable materials tomorrow. Vehicle parts offer recycling opportunities for materials such as steel, aluminum, plastics, antifreeze, and batteries, as well as whole parts such as tires, seats, engines, and alternators.

Just the Facts Each year, nearly all of the 27 million cars around the world that reach the end of their useful life are recovered for recycling. Automotive recyclers now can recover nearly 80 percent of the total materials by weight from a vehicle, according to the United States Council on Automotive Research (USCAR) an organization of auto manufacturers that work together on shared technological and environmental concerns. The remaining 20 percent of vehicle materials that cannot be recycled is called auto shredder residue (ASR). ASR includes plastics, rubber, wood, paper, fabric, glass, sand, dirt, and ferrous and nonferrous metal pieces. Five million tons of ASR are disposed of in landfills each year. Consumers purchasing used or reconditioned parts save 50 percent or more compared to the cost of purchasing new parts. More than 25 million tons of materials are recycled from vehicles each year. Automotive recycling is generally calculated separately from the MSW recycling rate. Nearly 90 percent of automotive aluminum is recovered and recycled. Although this aluminum represents less than 10 percent of the average motor vehicle by weight, it accounts for roughly half of the vehicle's value as scrap. Auto recyclers supply more than one-third of all ferrous scrap (iron and steel) to the U.S. scrap processing industry. When manufacturers use scrap iron and steel instead of virgin ore, they reduce air and water pollution by more than half during the manufacturing process.

Recycling Automotive Parts

Cars are recycled in four steps: dismantling, crushing, shredding, and resource recovery. In the dismantling stage, processors recover the fluids and take apart the usable parts and components. These include batteries, wheels and tires, steering columns, fenders, radios, engines, starters, transmissions, alternators, select plastic parts and components, glass, foams, catalytic convertors, and other components, based on aftermarket demand. The processor then crushes the vehicle and loads it onto the vehicle shredder. The shredder grinds the vehicle into fist-sized pieces, which are then separated into ferrous and non-ferrous (aluminum) metals, as well as ASR. After separation, the recovered metals are remelted at the mills, and the ASR is landfilled.

Lifecycle Assessment
Lifecycle Assessment (LCA) might be a valuable tool for striking a balance between recycling and other environmental priorities in automotive parts design. Researchers worldwide now are actively developing LCA and considering

The International Federation of Automotive Engineering Societies is an international organization representing automotive engineers and automotive societies. The Steel Recycling Institute (SRI) , a unit of the American Iron and Steel Institute, provides information on recycling for all steel products. global standardization and regional differences.

Scientists are developing highly advanced technologies, which will allow more effective recovery of the materials currently not reused from end-of-life vehicles. Such advancements include infrared polymer identification; automated, high-speed materials identification (for plastics, aluminum alloys etc); feedstock recycling; and paint removal/treatment.

Case Studies

Vehicle Recycling Partnership, Automotive Shredder Residue Recovery The U.S. Department of Energy sponsored a project with the Vehicle Recycling Partnership(composed of Ford, General Motors, and DaimlerChrysler) and the American Plastics Council (APC) to develop technology to recover recyclable materials from ASR. The partners successfully constructed a pilot bulk separation system that yields a plastics concentrate (about 45 percent by weight of ASR), a polyurethane foam fraction (about 10 percent by weight of ASR) and an oxides fraction (about 45 percent by weight of ASR). The partnership continues to investigate effective ways to recycle each fraction of the ASR.

Fauquier County, Virginia In Fauquier County, Virginia, county officials pick up abandoned and junk vehicles for free. This program is designed to encourage citizens to remove unwanted vehicles from their property. The vehicles are recycled free of charge.
