Notes:
1
denotes that all waste handling and composting operations are carried out indoors. This includes waste reception, shredding, addition of amendment
and mixing of feedstocks, loading of material into first stage and second stage enclosed composting bays, screening of compost and loading of
compost into Animal By-Product treatment tunnels. The containment principle applies here to ensure no emissions of odours escape to atmosphere.
2
denotes that process air will be collected directly from the enclosed composting bays and directed to an acid scrubber for ammonia removal and then
be ducted directly to the optimised biofiltration system for treatment.
3 3
denotes that in order to ensure negative pressure within the building a total volumetric airflow rate of 30,000 m /hr of air will be ventilated from the
composting building headspace. Makeup aeration air for the composting tunnels will be taken from the building while additional building ventilation air
will be extracted to ensure effective negative ventilation.
