Division BAT 29 In order to reduce VOC emissions from publication rotogravure printing, BAT is to use a toluene recovery system based on adsorption and one or both of the techniques given below.
United Kingdom
| Technique | Description | |
|---|---|---|
| (a) | Use of retention inks | Retention inks slow the formation of the dried film surface, which allows toluene to evaporate over a longer time and therefore more toluene to be released in the dryer and recovered by the toluene recovery system. |
| (b) | Automatic cleaning systems connected to the toluene recovery system | Automated cylinder cleaning with air extraction to the toluene recovery system. |

BAT-associated emission level (BAT-AEL) for fugitive emissions of VOCs from publication rotogravure printing
| Parameter | Unit | BAT-AEL(Yearly average) |
|---|---|---|
| Fugitive VOC emissions as calculated by the solvent mass balance | Percentage (%) of the solvent input | < 2,5 |
The associated monitoring is given in BAT 10.
