Insight and inspiration in turbulent times.
Biogas is produced when organic matter biodegrades under anaerobic conditions (that is, in the absence of oxygen). This process produces a mixture of gases – primarily methane, some carbon dioxide and tiny portions of other gases such as hydrogen sulfide.
An increasing number of sewage treatment plants in the U.S. and Europe are processing food waste in anaerobic biodigesters, keeping more garbage out of landfills, reducing methane emissions, and producing energy to defray their operating costs.
Enter FirstEnergy Stadium in Cleveland, where a new partnership with the Cleveland Browns and the Innovation Center for U.S. Dairy has implemented a new system to will divert an estimated 35 tons of stadium food waste from landfills into biodigesters for conversion into energy.
Many have heard about how cow farts and manure decomposition both produce harmful methane gas, which contributes to global warming pollution. What is less known, though, is that farms can convert cow manure into renewable biogas, which can power aspects of the farm and prevent that methane from reaching the atmosphere.
