If you thought anaerobic digester systems were only possible for
large-scale dairy farms, think again. Emphasizing odor control and
manure management for 100 to 300 cow operations, a report generated
by The Minnesota Project details six options for anaerobic manure
digestion on Minnesota farms. "Because 96% of Minnesota's dairy
farms have 200 or fewer cows. This report is very important. It
shows how the majority of dairy farmers could provide and use another
form of renewable energy," Doug Peterson, President Minnesota
Of the six model systems included in the report, five are designed
for individual farms, while one is a community digester model. Rather
than aiming for excess energy generation as some large-scale digesters
do, these six system models focus on the benefits of simpler systems
that cost less and are easier to build and operate.
“Farmers have always recognized the value of manure. Anaerobic
digestion of manure is another means of tapping into its value and
Mr. Goodrich’s work is key to expanding the utilization of
this technology to more farmers. This is beneficial to the farmer
and the non-farmer alike because anaerobic digestion improves the
sustainable dairy ecosystem,” Bob Lefebvre, Executive Director,
Minnesota Milk Producers.
