Duke Energy has finalized a second deal in 2016 to buy captured methane gas derived from swine waste.
In March, the company announced a project with Carbon Cycle Energy to use swine waste-derived gas at four power plants in North Carolina.
For its newest project, the Charlotte, N.C.-based utility company will partner with Optima KV, a Wilmington, N.C.-based partnership that brings together experts in bioenergy, agriculture, project finance, and environmental stewardship. The project will be located at farms in Kenansville, N.C. -- the heart of Smithfield Foods' pork operations.
