5361- Kilmainhamwood Compost Facility Extension- EIS
Scope of the Works
The main aims of this odour assessment include:
� Perform an odour assessment on the exhaust of biofiltration system 1 and 2 (existing facility) in
accordance with EN13725:2003.
� Perform predictive odour impact assessment of the existing facility operations in accordance with
recognised assessment methodology in order to determine the potential of odour impact in the
vicinity of the existing facility.
� Perform predictive odour impact assessment of the proposed facility design operations in
accordance with recognised assessment methodology in order to determine the potential of
odour impact in the vicinity of the proposed facility design.
� Provide a list of key criteria for odour minimisation and management at the facility.
9.2.1.1 Key Decision-Making Processes in Operation of the Odour Management System
The following key design elements must be implemented into the odour control and management
system for the existing and proposed composting facility design. These include:
1. The prevention of generation and release of odours from the process is key to ensure no odour
impact in the vicinity of the facility. These include the implementation of odour management
procedures, which will take account of daily operations to reduce the overall generation of
odours from the facility. These include:
� Responsible operation and handling of material.
� Closed-door management strategy.
� Facility management and cleaning procedures for all surfaces in contact with material.
� Material acceptance procedures to include enforcement of acceptance of enclosed
material loads, type of material accepted into the facility and the procedures for handling
materials within the facility.
� Other elements include the implementation of an odour management plan and operation
and maintenance management plans for the odour control system.
2. Containment of odours within the composting facility building is essential to effective capture
and treatment. The current containment measures are used within this Odour Management
system design and include:
� The composting building is covered with an inner impermeable membrane to prevent
odour leakage from the building fabric. All building fabric surfaces are regularly audited
for leakage and repaired where necessary.
� The current composting operations are open bay where positively displaced odour
emissions are vented to the headspace of the building. This unnecessarily increases air
handling capacity for the building and increases difficulty in capture and containment of
odour emissions for treatment. This requires optimisation for ammonia scrubbing of the
composting tunnel emissions.
