Are you a swine farmer, or have a friend who raises pigs? Are you interested in maybe adding an anaerobic digester to your operation to produce energy and control odors? If so, you will be interested to know that Penn State Extension has released a new spreadsheet-based tool for analyzing swine farm anaerobic digesters that produce Renewable Natural Gas (RNG) that is delivered to the natural gas pipeline network.
This tool is available on the Penn State Extension website, and is free for downloading and use.
The tool utilizes inputs about the farm's size and operating characteristics, and calculates the expected performance of the digester in terms of its economic productivity.
