Due to the close proximity of neighbours and the Fife coastal walk the plant processes were all enclosed in buildings and extracted air passed through a peat bed Biofilter before being discharged into the atmosphere. Despite odour abatement measures odour complaints were still received, although the client introduced further odour control measures complaints continued, a complete redesign was required.
