Tag: digesters

These seedlings are an example of the digester's potential to spawn side businesses. They are being grown by UW-Madison graduate student Brian Zimmerman and Madison resident Taylor Jacque, in a greenhouse powered by the waste heat from the community digester near Waunakee.

How to make a digester profitable: Veggies and poker chips

by Jessica VanEgeren April 30th, 2014June 20th, 2014 Why you can trust WisconsinWatch.org

The greenhouse and its veggies are one example of a new cottage industry popping up across the country to capitalize on the waste energy, methane gas and the nutrient-rich solids that are emitted from a digester.

The community digester located near Waunakee is the stateÕs first to process manure from more than one farm. Roughly 100,00 gallons of manure from 2,400 cows on three nearby farms is pumped daily through underground pipes to the digester. Its purpose is to keep phosphorus from polluting the Yahara watershed.
