LAFARGE CEMENT UK—COMPARISON OF FIGURES FOR FUEL
TRIALS ON BASIS OF INTEGRATED ENVIRONMENTAL INDEX, (IEI) AND ENVIRONMENTAL
QUOTIENT (EQ) AIR

|
| Dunbar | Tyres | 25%

Notes:
Dunbar tyres refers to operation with raw mill on mode, with raw mill off improvement in EQ air is +26 per cent.
Cauldon tyres refers to increase from 30 per cent to 50 per cent tyres and figure is estimated: no formal calculation required by Agency.
Weardale SLF: IEI methodology used was different at that time and hence numbers for IEI larger, using modern methodology numbers would be changed but percentage improvement same.
