Parisi proposes $3 million to study renewable fuel option
Dane County Executive Joe Parisi has allocated $3 million in the next budget to study the feasibility of a digester that can turn manure into renewable fuel, according to a Wisconsin State Journal report. Much of the manure waste from 155,000 cows in the county is spread on fields and eventually gets washed into lakes, where it can trigger algae blooms. Commercial digesters process manure from cows, capturing methane and extracting fertilizer that can be returned to farmers in concentrated form. Parisi announced the proposal saying a digester would be a “game changer” for water quality while also eliminating a major source of greenhouse gas emissions. He argues that a feasibility study will look at options for manure transportation and handling, possible pipeline needs, and what components would be needed to process large volumes of waste in the smartest way possible.
