Republic Services Inc. has opened a landfill gas-to-energy project in Argos, Ind.

The new 6-megawatt project at the Phoenix-based Republic’s County Line Landfill comprises four engines operating at one energy generation facility. The unit can generate enough energy to power more than 3,200 area homes, the firm said in a news release.

Republic has partnered with Aria Energy on the design, development and management on the Indiana project. The two firms have worked together on four projects to date with a combined generation capacity of more than 39.6 megawatts of electrical power. They are working on another two projects that will generate an expected 15 megawatts of power.

"We are serious about developing innovative uses for landfill gas whenever possible," said Mark Watson, area president of Republic.

Republic employs 120 in the South Bend, Elkhart, Plymouth and Rochester area, serving 14 municipalities and about 4,000 commercial customers. The company operates two hauling divisions, a recycling facility, a transfer station and a landfill in the region.

The company has implemented 73 landfill gas-to-energy projects nationwide.
