Event Title

Biodigestion for reducing carbon emissions

Presentation Abstract

As our climate continues to change due to the amount of carbon we release into the atmosphere, we need to develop more methods for reducing the amount of carbon we release. Methane (CH4) is the second most prevalent greenhouse gas emitted in the United States from human activities. Methane's lifetime in the atmosphere is much shorter than carbon dioxide (CO2), but CH4 is more efficient at trapping radiation than CO2. Pound for pound, the comparative impact of CH4 on climate change is more than 25 times greater than CO2 over a 100-year period.

Animal waste and food waste release methane gas during the decomposition processes. Currently most of this waste is disposed of in ways that are not designed to capture the methane gas and it is freely released into the atmosphere. Bio-digester facilities can capture the methane and use it for producing electricity, use it as renewable natural gas, or just flare it off to breakdown the methane into less damaging carbon compounds.
