Summary:
Recent work at the University of Minnesota suggests that biofiltration may effectively reduce odour concentration generated from intesnive livestock operations. Exhaust gas generated from mechincally ventilated swine buildings is passed through a biofilter, such as a loam, peat or compost allowing the air to filter or percolate through the material.
