Renewable Energy from Landfill Gas. Corporate Overview. Headquartered in Houston, Texas Operations in 47 states, District of Columbia, Canada and Puerto Rico Nearly 20 million customers Collect and process around about 115 M tons of waste 273 active landfills Over 357 collection operations
1. Double ourwaste based energy production
2. Triple the tons of recyclable materials processed
3. Invest in cleaner technologies
4. Preserve and restore more wildlife habitats across North America
Regulations governing landfill gas:
The first priority for a renewable energy project is to be compatible with landfill operations and comply with all regulations and protect the public and environment
Produced by the natural anaerobic decomposition of organic waste in the landfill
Typical Landfill Gas Percentages
Natural gas fossil fuel is methane, so landfill gas can be used for the same purposes as natural gas
Small on-site plants, off-site plants, or blended with fossil fuel at utility plant
Heating Fuel (“Medium BTU”)
Medium BTU gas used in steam boilers, kilns, dryers, greenhouses, liquids disposal, etc.
Process to Natural Gas (“High BTU”)
Remove carbon dioxide, nitrogen, oxygen, and other constituents, and deliver methane to natural gas pipeline
Process to natural gas, then compress or liquefy to produce CNG or LNG for alternative fuel vehicles
Landfill business unit supports the plant with backup operators, compliance management, community relations

Renewable Energy Portfolio Standards (RPS)
Value range = $3 - $55 per mwh
State policy that requires electricity producers to obtain a minimum percentage of their power from renewable energy resources.
Producers purchase (RECs) from qualified resources in amount needed to comply with standard. Sales may cross state lines.
Voluntary Utility Renewable Energy Programs
Value range = $1 - $10 per mwh
Customers pay a premium for blocks of renewable energy, and the utility purchases RECs from renewable resources, resulting in premium payment by utility to renewable resource.
Voluntary Corporate Renewable Energy Programs
Value range = $0.50 - $5 per mwh
Corporations purchase RECs to support renewable energy development.
“Section 45” Federal tax credit of $11/mwh can be claimed by the owner of a renewable energy generation facility which uses landfill gas as fuel.
Tax credit can be claimed for a period of 10 years after the placed in service date.
Facility must be placed in service prior to January 1, 2013 to qualify.
To be eligible, no entity could have claimed previous Section 29 (45k) tax credits at the landfill
Conceptual Project: 4.8 MW
Capital Cost: 4.8 MW x $1.5 million/MW = $7.2 million
Capacity Factor: 5% parasitic load, 95% run rate = 90% CF
Output: 38,000 mwh per year
Combined State & Federal tax rate = 39%
Section 45 tax credits: 38,000 x $11 = $418,000 / year
10 Megawatts = 60 Acres
Knowledge of landfills’ electric generation capability moves opinion in a positive direction, with 72% of respondents having a more positive opinion
Knowledge of a planned electric generation plant made 87% of respondents more likely to favor a landfill expansion
