The Gardiners wanted to diversify their farm
operations and have a viable succession plan for their son, who is currently
operating the farm. Additionally the consideration of an anaerobic digestion
facility was further supported by Provincial funds having been made available
for the construction of such systems.
The use of Rumensin necessitated a different
start-up procedure. While the slow introduction of Rumensin manure had been
directed, the operators chose not to follow these instructions. Thus the Rumensin
manure did not allow the methanogenic bacteria to grow, and the digester had
to be re-started.
In the second start-up, dairy cow manure from an adjacent
farm, as well as effluent from a nearby digester were brought in and the methanogenic
bacteria were acclimatized to the Rumensin manure in prescribed quantities
and feeding rates until full production was reached.
The system’s effluent fertilizer
is applied to the farm’s crop fields.
