LINCOLN, Neb. (AP) - A landfill project built by the city of Lincoln and its public power utility to capture greenhouse gases and use them for energy has brought in some cash for the city.

The project uses 76 wells to capture landfill gas that would otherwise end up in the atmosphere, the Lincoln Journal Star reported (https://bit.ly/1GP1wJW ). The gas, made up mostly of methane and carbon dioxide, is sent through a system of pipes to nearby Terry Bundy Generating Station, where it is burned to produce electricity.

Burning landfill gas as fuel means Lincoln Electric System is “taking a potent greenhouse gas and turning it into a less potent greenhouse gas,” said Tom Davlin, manager of projects engineering for the utility.

Donna Garden, assistant director of the city Public Works and Utilities Department, said Lincoln received carbon credits from the project, some of which it sold last year for $19,365. Another sale is pending for $35,000.

The credits are a financial way to measure carbon dioxide removed from the air.

There are two markets for carbon credits: the Regional Greenhouse Gas Initiative, a cooperative effort among nine Northeast states to reduce greenhouse gas emissions, and the Western Climate Initiative, made up of seven Western states and four Canadian provinces.

Lincoln earned 50,120 carbon credits for 2011 and 128,464 in 2012, Garden said. No figures are available for 2013 and 2014 because they are still being verified, she said.

Garden said the city sold the carbon credits through a broker and she does not know who bought them. Money from the sale went back into the city’s occupation tax fund and are used for such things as landfill operations and recycling efforts, she said.
