Garbage Power

The Philadelphia Inquirer has an article on landfill gas power generation in New Jersey - N.J. now turning its garbage into energy.
Standing atop the 400-acre 1-E landfill, you get a panoramic view of the Meadowlands sports complex to the north and the New York City skyline to the east. You're also standing on a critical part of New Jersey's, and the nation's, energy future.
Decades worth of household trash, construction waste and assorted refuse buried in the landfill is providing electricity to thousands of homes. "It's like you're buying back your own garbage, but in a different form," said Tom Marturano, director of solid waste and natural resources for the New Jersey Meadowlands Commission, which owns and operates the 1-E site.
The Kearny site is among 21 landfills in New Jersey where methane gas produced by decomposing garbage is used as fuel to generate electricity, according to the state Board of Public Utilities. That is almost as many as in the state of Texas, and more than the combined number in Georgia, Mississippi, Louisiana, Arkansas and Oklahoma.
Nationwide, the federal Environmental Protection Agency counts 455 landfills that use their methane to generate electricity and has targeted more than 500 more as potential candidates through its Landfill Methane Outreach Program.
One of New Jersey's leading environmentalists envisions the state's landfills someday making more use of their sites by installing wind and solar power to supplement methane.
"We see landfills as potential New Age energy plants, because you can combine all three and create a steady source of power - and not everybody wants a windmill in their back yard," said Jeff Tittel, executive director of the New Jersey chapter of the Sierra Club.
Marturano cautioned that adding wind farms might take a while since landfill surfaces are constantly shifting, but the Meadowlands Commission already has plans to install 20 acres of solar panels on the southern side of the 1-E landfill.
Gov. Jon S. Corzine's Energy Master Plan for the state touts landfill methane gas as one of the state's key renewable energy sources. It hopes renewable sources will combine to supply 30 percent of New Jersey's electricity consumption by 2020. According to the plan, New Jerseyans produce 6.7 pounds of trash per day, 50 percent more than the national average.
