Study Finds Alcoa Forged Aluminum Wheels Dramatically Cut Carbon Footprint of Commercial Vehicles, Supporting Sustainable Transportation
Savings of Switching One Truck from Steel Wheels to Alcoa Forged Aluminum Wheels Equals Average Annual Carbon Footprint of American Household
CLEVELAND--(BUSINESS WIRE)-- Alcoa (NYS: AA) today released the findings of a peer-reviewed life cycle assessment (LCA) which concludes that Alcoa aluminum wheels substantially cut the carbon footprint of commercial vehicles. In North America, the study found that substituting 18 conventional steel truck wheels with Alcoa aluminum wheels cut carbon emissions by 16.3 metric tons over the lifetime of the wheels. In Europe, replacing 12 steel wheels with aluminum cut 13.3 metric tons of carbon emissions. In addition, the study found that the use of Alcoa forged aluminum wheels over steel wheels can be viewed as an active and highly efficient investment into the reduction of greenhouse gas emissions in the commercial vehicle sector.
"As commercial vehicles face stricter regulations around reducing carbon emissions, this life cycle assessment confirms that Alcoa forged aluminum wheels support sustainable transportation and can help trucks and trailers to be greener," said Tim Myers, President, Alcoa Wheel and Transportation Products. "Compared to steel, the lighter weight and infinite recyclability of Alcoa forged aluminum wheels support greener vehicles that cut down on fuel use and carbon emissions."
"Life cycle assessment is the universally accepted method to comprehensively assess the environmental impact of a product," said Dr. Christoph Koffler, Technical Director of PE International, Inc. & Five Winds Strategic Consulting, which conducted the study. "Our findings are based on the full life cycle of Alcoa forged aluminum wheels—from the raw materials, through the production, distribution, use, disposal, and recycling of the product."
This analysis is the most comprehensive and transparent comparative LCA ever conducted on aluminum and steel truck wheels. It analyzed the entire "cradle-to-grave" production process of commercial vehicle wheels—from bauxite mining to wheel manufacturing, through a truck wheel's use phase and end-of-life, including recycling and land filling. The study incorporated the latest available information on energy and material consumption, greenhouse gas emissions and other environmental releases. Alcoa provided primary data for aluminum wheel production from five facilities: two in the United States (Cleveland and Barberton, OH), one in Mexico, Hungary, and Japan. PE International provided upstream data for fuels, raw materials, and steel wheel manufacturing processes, including primary metals and chemicals. The study conformed to ISO methodology and was peer reviewed by respected professionals in the LCA community, including experts from the world-renowned Technische Universitat Berlin and the University of Michigan.
Major findings of the study include:
- The 16.3 metric ton savings of switching one 18 wheel truck from steel wheels to Alcoa forged aluminum wheels in North America equals the average annual carbon footprint of a four person American household.
- Alcoa wheels maintain their value throughout their lifetime and have an end-of-life scrap value that is nearly equal to that of primary aluminum.
- For volume restricted vehicles in North America that are unable to add additional payload, switching from steel to Alcoa forged aluminum truck wheels produces an average lifetime savings of more than 520 gallons of fuel. In Europe, these savings amount to more than 1,942 liters.
- For mass restricted vehicles in North America, where lighter weight aluminum wheels allow for additional payload, switching from steel to Alcoa forged aluminum truck wheels results in the ability to carry 414 lbs. of additional payload per haul with the same fuel consumption. In Europe, the amount totals 215 kg of additional payload per haul. This benefit reduces the fuel consumed per pound of cargo, thus increasing the efficiency of transport.
- While aluminum wheels require more energy to manufacture than steel wheels, the light weight and recyclability of aluminum allow for a net energy savings throughout the life cycle of an aluminum wheel. A truck with aluminum wheels can see a CO2 "break even mileage" as early as 205,000 miles, or about two years. Once this mileage is reached, all the travel on aluminum wheels produces CO2 and energy savings.
Alcoa and PE International will present the findings of the LCA at the 12th Annual American Center for Life Cycle Assessment Conference in Tacoma, Washington on Tuesday, September 25, 2012. For more information on the conference, please visit http://lcacenter.org/LCAXII.aspx.
