University of Manitoba says anaerobic digestion by itself will not reduce
phosphorous output from hog operations.
The
province has referred to anaerobic digestors as being part of the solution to
reducing the amount of phosphorous entering waterways from livestock
operations.

Cicek says digestion does not really do anything to phosphorous, except it
makes it more mobile, releasing some from the organic material into the liquid,
which in return makes it more recoverable.
He
says having an anaerobic digestion system coupled with a struvite recovery
system would allow for reducing phosphorous content in your final product.
Cicek
says with cheap, green energy, a cold climate and minimal government support,
it’s tough to make the case for anaerobic digestion in Manitoba.
