Environmental and Economic Benefits of Capturing Swine Manure Methane

Workshop and Butler Farms Tour: September 18, 2008

Sampson County Agri-Exposition Center
414 Warsaw Road
Clinton, North Carolina 28328

Increasing odor, air and water quality concerns have created significant difficulties for the viability and growth of the livestock industry in North Carolina. Management of air emissions and nutrients are major issues facing producers and the citizens in the state. However, effective mitigation technologies such as anaerobic digesters and lagoon covers are emerging. These technologies not only address many of the environmental concerns surrounding manure management, but also create opportunities for revenue from energy generation and carbon credits.

This free workshop, hosted by Environmental Credit Corporation (through a U.S. Department of Agriculture grant), EPA Region 4, and AgSTAR, provided a broad overview of anaerobic digestion of swine manure and other related issues. The presentations are posted below.
