In order to minimise limestone consumption, BAT is to use one or a combination of the following techniques:
| Technique | Applicability | |
|---|---|---|
| a | Specific quarrying, crushing and well directed use of limestone (quality, grain size) | Generally applicable in the lime industry; however, stone processing is dependent on the limestone quality |
| b | Selecting kilns applying optimised techniques which allow for operating with a wider range of limestone grain sizes to make optimum use of quarried limestone | Applicable to new plants and major upgrades of kiln. Vertical kilns can in principle only burn coarse limestone pebbles. Fine lime PFRK and/or rotary kilns can operate with smaller limestone grain sizes |
