Anaerobic Digestion and Bio-Energy

Rising energy prices, energy security, and environmental concerns have driven interest in renewable energy. There are many renewable energy applications in agriculture. We have undertaken a variety of research projects designed to develop a better understanding of economic issues related to bio-energy projects. The primary focus of this work has been on understanding economic issues related to anaerobic digestion of livestock waste. The work listed below provides some background on the topic and addresses some of the key challenges to adoption. You will also find two spreadsheet based tools which can be used to help evaluate the economics of an anaerobic digestion project. When using the tools be sure to read the accompanying input guides and research bulletins. These will explain the inputs required to make use of the spreadsheets.

Spreadsheet Analysis Tools for Anaerobic Digestion:

• General Assessment: This tool can be used for a general economic assessement of an anaerobic digestion system.
  
• FarmWare Assessment: This tool is desinged to conduct an analysis from the outputs the US EPA's FarmWare program.
