FSE’s, Monitor Compliance,
1,200 FOG Licences Issued, 2,394 Monitoring Inspections
Types, description and spread of FSE’s inspected
Quantities of FOG Recovered, (Fast Food and Restaurants)
Results of First Annual Report


2,500 tonnes of FOG Recovered
>800 Grease Traps installed
Work Package 2 – Sociological Issues
Tackle Problem at Source
Change Public Perception
Persuade change in approach
Educate and Advise (Leaflets)
Good Kitchen Practices
Management of Grease Removal Units
Reduce Waste to Landfills and Sewers (May be a Conflict!)
Common Message Required from Solid Waste and Wastewater
Industry
Legislation and Licencing
Midleton Case Study
€40,000 Expenditure/Annum on Fog Removal/Control
Over 78 FOG Hotspots
Study commenced June 2006, Completed June 2008
Studies carried out at 18 locations
Cross Section of Food Service Establishments (FSE’s)
Cross Section of Grease Removal Units (GRU’s)
Passive Systems, Mechanical Systems, Biological Dosing Units,
Hybrid Units, etc.
Statistics gathered, Better understanding of systems available,
need for maintenance, outlet for FOG collected, proper
recording, better kitchen practices
Greater role for Environmental Health Officers
Need for greater Public Awareness and Stakeholder involvement
Midleton FOG Case Study Report available form WSNTG
