GM Two-Mode hybrid transmission plant goes landfill free

The factory that will be turning out all the Two-Mode hybrid transmissions for General Motors, Chrysler, Mercedes-Benz and BMW starting this fall will be doing it without sending anything to the dump. Everything that comes into GM's Baltimore transmission plant for the production process will leave either in the form of product or else it will be recycled or re-used.

Baltimore is the eighth GM plant to go land-fill free with ninety-seven percent of the materials being repurposed and the rest going to energy generation in an on-site waste to energy plant. Metal chips and scrap from machining processes are shipped to GM foundries or other plants to be melted down and re-used, while paper products are recycled and oil is reconditioned for reuse. Full details are in the press release after the jump.

GM's Baltimore Transmission Facility Achieves Landfill Free Status

Plant's manufacturing process wastes are completely reused or recycled

Baltimore, MdGeneral 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.

Baltimore Transmission is the eighth GM facility to reach landfill-free status. Other GM landfill-free facilities include plants in Tonawanda, NY; Flint and Wixom, Mich.; Gunsan and Bupyeong, Korea; and Kaiserslautern and Eisenach, Germany. In North America, GM facilities have reduced non-recycled waste by over 76 percent since 1997, by either eliminating the generation of waste or increasing recycling. These same North American facilities currently recycle nearly 88 percent of the waste they generate. Globally, the recycling rate for GM facilities is approximately 86 percent. GM was one of the first organizations – and to date is the only automaker -- inducted into the U.S. EPA WasteWise Hall of Fame. This recognition was the result of continual outstanding waste reduction and recycling efforts at GM. For more information about GM environmental initiatives go to

The GM Powertrain Baltimore transmission plant, which is located in White Marsh, Md., employs approximately 400 people. Last year, the plant produced 189,000 transmissions that are featured in the award winning Chevrolet Silverado and GMC Sierra full-size pickups. The 425,000 square foot facility opened in 2001.
