GM's Baltimore Transmission Facility Achieves Landfill Free Status: Process wastes are completely reused or recycled

General Motors Corp.’s Baltimore transmission plant, which will build the industry’s first two-mode hybrid transmission for GM’s full-size SUVs and pickups, announced today that it has officially achieved “landfill free” status – meaning it will no longer send any waste from its production operations to landfills.

Changes at the plant – the new landfill-free manufacturing process and a new hybrid drivetrain – will provide significant environmental benefits.

“Our Baltimore facility is a great example of how GM is working to reduce the impact of both our operations and our vehicles on the environment,” said John R. Buttermore, GM Powertrain vice president of global manufacturing. “Many manufacturing plants generate waste along with their products but here at our Baltimore plant, fuel-efficient transmissions for our vehicles are our only output. All wastes generated here are recycled or reused in some way. We are very proud of the environmentally responsible work that has been done working jointly with the leadership of UAW Local 239 and our Baltimore employees that made this possible.”

The GM Powertrain Baltimore plant will be the exclusive manufacturer of GM’s all-new two-mode hybrid transmission. This leading hybrid technology will increase the fuel efficiency of GM’s full-size SUVs and pickups up to 25 percent over conventional gasoline Powertrain systems. The transmission will debut in the 2008 Chevrolet Tahoe and GMC Yukon two-mode hybrids that will be available in the market later this year.

Buttermore added, “With today’s announcement, Baltimore becomes the eighth GM facility worldwide to reach zero landfill status. Eliminating waste to this degree is a GM manufacturing priority and is the right thing to do for our business and the environment.”

As of May, the GM Powertrain Baltimore transmission facility has been operating with landfill-free status for waste materials generated directly from its daily operations. This year, approximately 97 percent of the waste materials from the site (7,300 tons) will be recycled or reused and 3 percent (215 tons) will be converted to energy at a waste-to-energy facility. In 2006, the plant was close to landfill-free status, with 99 percent of its waste recycled, reused or converted to energy.

Items that are recycled or reused at the site this year will include approximately 510 tons of aluminum, 600 tons of steel, 10 tons of alloy metals, 360 tons of wood pallets, 3 tons of paper, 20 tons in empty totes and drums, 250 tons of used oil, 220 tons waste water residual, and 5,400 tons of returnable packaging.

Part of the challenge in reaching landfill-free status is finding uses for recyclable materials. Today, even the tiniest scrap of trash is put to beneficial reuse. Aluminum is recycled by GM foundries that produce engine and transmission components. Steel, alloy metals, and paper are sent to recyclers for reconstitution into a variety of products. Used oil is reconditioned for use as a manufacturing fuel additive. Wood pallets are given to Baltimore area fire departments or sent to energy recovery. Empty drums and totes are refurbished and used again and again.

The plant’s total elimination of waste is having an immediate impact on carbon dioxide (CO 2) emissions. Over 13,000 tons of CO 2 will no longer enter the atmosphere each year as a result of the plant’s manufacturing operations, which avoid CO 2 emissions normally generated when waste is landfilled.

Additional reductions in CO 2 emissions will occur when GM’s hybrid vehicles using the new two-mode transmission begin appearing on roadways late this year. A 25 percent increase in fuel economy, and associated CO 2 emission reductions, will result from the hybrid system. The hybrid system uses both electric motors and a gasoline engine to power the vehicle.

Previously, General Motors announced a goal to reduce CO 2 emissions from its North American manufacturing facilities by 40 percent by 2010, based on 2000 baseline levels. In addition, General Motors recently became the first carmaker to join the U.S. Climate Action Partnership (USCAP), a non-partisan group of companies and non-governmental organizations formed to support a mandatory, economy-wide, market-driven approach to climate protection.
