TURNKEY RECYCLING &
ENVIRONMENTAL ENTERPRISES (TREE)
TURNKEY RECYCLING &
ENVIRONMENTAL ENTERPRISES
• Owned by Waste Management, Inc.
• State-of-the-art ECO-Park located on 1300 acres in Seacoast Area of
Southern New Hampshire.
• Park includes three double lined landfills, 2 power plants, 5 flares,
MRF, Collection Company, Citizen Drop-off, and Leachate Pre-
treatment Plant.
• Site is certified Wildlife Habitat Area under the Wildlife Habitat
Council.
• Recreational and Community Projects on site include: a homeless
shelter, golf range, hiking trails, canoe launch, model airplane field and
a park.

Project Background
• Long standing relationship between WM and UNH.
• WMNH/TREE currently has two LFG to Electricity plants producing 9
megawatts of power. Waste Management has over 100 landfill gas to
energy projects nationwide, and will build 60 more in the next 5 years.
• Site is currently using approximately 4000 scfm of LFG and producing
over 8000.
• WM approached UNH regarding project concept.
• Contract negotiated in 2006/2007. 10 year contract with options for
renewal up to 7000 scfm of gas is committed to UNH if available above
site power plant demands.
TREE Gas Recovery Plant 1
Project Details
• 12.7 mile, 12 inch HDPE pipeline travels along public roads, turnpike,
and private rail right of way.
• Processing plant located at landfill will remove CO2, H2S, and
Siloxanes. Minimum methane content required is aprox. 82 %.
• Two 3520 CAT engines will provide parasitic load for processing plant,
site gas blowers, and site leachate pump station.
• Plant will be designed, constructed, and operated by SCS Energy as
contractor for UNH.

Environmental/Financial Benefits
• 80% - 85% of campus energy will be from a renewable source
• Reduce UNH carbon footprint
• Landfill gas is carbon-neutral
• Reduce exposure to energy market fluctuation
• Improve cost stability and predictability
UNH Power Plant
• UNH Plant supplies approximately 85% of campus energy needs.
• 7 Megawatt Siemens turbine supplies electric and steam for campus.
• New 5 megawatt Solar Mercury turbine to be installed for producing
electricity for scale to grid.
• Campus boiler will also be powered by landfill gas.
• Automatic Natural gas mixing valve will assure minimum BTU’s are
provided to Turbines.

Project Financials
• Total Project cost estimate is 44 million dollars
• Project funded by UNH with WM contributing 1.2 million.
• UNH pays WM for gas based on BTU’s after processing.
• Pricing is based on Natural gas and electric indices depending on devise
using gas.
• UNH to sell Renewable energy credits from campus and WM from
3520’s located at landfill.
Current Project Status
• Pipeline was completed last Fall/Winter, by RH White.
• Directional drilling was used to minimize wetland disturbances.
• UNH was able to fast track permitting through state agencies and is
exempt from local permitting.
• Processing plant construction will begin this month with completion
scheduled for Jan, 2009.
• Turnkey has over 300 gas wells and over 200 of them have dedicated
pneumatic pumps for dewatering into a separate force main.
