Renewable Energy Education Field Days: Anaerobic Digesters – Financing & Technology

Financing and technology of anaerobic digester systems were the subject of two webinars Wednesday, March 14, 2012.  Part of the Renewable Energy Education Field Day series, the webinars were targeted to landowners, community leaders and dairy farmers with operations of all sizes.

The webinars were a collaboration of Farm Foundation, NFP, USDA Rural Development, USDA Office of Energy Policy and New Uses, the U.S. Environmental Protection agency, Innovation Center for U.S. Dairy and the Wisconsin Bioenergy Initiative of the University of Wisconsin.

This was the third Renewable Energy Education Field Day program.  Biomass was the subject of the first field day, which took place in November 2010.   The second field day on Oct. 26, 2011, was a webinar on the use of anaerobic digester systems on livestock operations in the Southwest.  A survey of the more than 300 individuals who viewed that webinar indicated interest in additional information on financing installation and maintenance of a digester system, and on the technology options to consider deciding the type of system to install.

Those topics were the focus of the March 14 webinars.  The webinars originated from the Pyle Center at the University of Wisconsin, Madison.

Presentations are posted below as speakers have permitted.
