Linde and Waste Management Receive California Governer's Award for Sustainable Facility

2010 Governor’s Environmental and Economic Leadership Award recognizes Altamont landfill gas to liquefied natural gas plant

HOUSTON and MURRAY HILL, N.J. – Nov. 16, 2010 -The world‟s largest biofuel plant producing liquid natural gas from landfill gas has received a 2010 California Governor‟s Environmental and Economic Leadership Award.

Recognized in the category of Sustainable Facility, the plant is located at Waste Management‟s Altamont Landfill and Resource Recovery Facility near Livermore, CA. The plant, which produces up to 13,000 gallons a day of near zero carbon fuel is owned and operated by a joint venture between Linde North America, part of The Linde Group, a world leading gases and engineering company, and Waste Management (NYSE: WM), North America‟s largest waste management company.

The award is California‟s highest environmental honor and recognizes exceptional leadership in conserving California‟s precious resources, protecting and enhancing the environment, building public-private partnerships and strengthening the state‟s economy.

Since Linde and Waste Management‟s plant began operating in September 2009, it has produced over two million gallons of clean, renewable fuel from landfill gas generated through the decomposition of waste at the Altamont Landfill. More than 300 of Waste Management‟s liquid natural gas collection vehicles in California are powered daily by the fuel generated at the Altamont facility, displacing tens of thousands of tons of greenhouse vehicular greenhouse gas emission annually.

“We are closing the loop in the waste disposal business,” said Duane Woods, senior vice president for Waste Management‟s Western Group. “Converting the landfill gas into a sustainable, clean alternative fuel source is the very essence of closed-loop recycling.”

“Our natural gas collection vehicles produce 97 percent fewer greenhouse gas emissions than comparable diesel fuel vehicles. Creating a healthier environment through reduced emissions and improved air quality is the essence of green innovation. Waste Management is proud to be recognized for this achievement,” Woods added.

Pat Murphy, president, Linde North America, said, “Linde is proud to improve air quality for millions of Californians. The ultra-low carbon fuel our plant produces already meets the California Air Resources Board‟s 2020 low carbon fuel requirements and the goals of AB32. Receiving the Governor‟s award confirms that our fully local, „wells to wheels‟ solution has hit the ball out of the park for the residents of California.”

“As usual, California is a leader in recognizing and promoting alternative fuels that help clean the environment, reduce our dependence on foreign oil and boost the economy. We hope this plant, and California‟s progressive thinking, can serve as a model for the rest of our country as we look to tap our unused biogas resources,” Murphy said.

By displacing 2.5 million gallons of diesel a year, the renewable biogas the plant produces eliminates over 30,000 tons a year of transportation greenhouse gases – the equivalent of removing over 5,000 passenger cars from the road. Nitrogen oxides (NOx) are reduced by nearly 200 tons and particulate matter emissions by over four tons a year.

Four California agencies contributed to this project, including the California Integrated Waste Management Board, the California Air Resources Board, the California Energy Commission and the South Coast Air Quality Management District.
