To Fight Food Waste, Madison Studies Anaerobic Digester
Methane gas is a major contributor to global warming, accounting for approximately ten percent of all greenhouse gas emissions. There are many man-made sources of methane gas, including agriculture and mining, but a major source is food waste decomposition in landfills. Recently, the city of Madison commissioned a study to consider a facility that would take food waste and convert it into natural gas, or methane. It’s called an anaerobic digester. Alder Tag Evers, who is one of the sponsors of the study, says the project is inspired by sustainability concerns.
