Division BAT 71 In order to reduce emissions of volatile organic compounds and polychlorinated dibenzo-dioxins and -furans to air from the co-incineration of waste with biomass, peat, coal and/or lignite, BAT is to use a combination of the techniques given in BAT 6, BAT 26 and below.

United Kingdom

Technique	Description	Applicability
a.	Activated carbon injection	See description in Section 8.5. This process is based on the adsorption of pollutant molecules by the activated carbon	Generally applicable
b.	Rapid quenching using wet scrubbing/flue-gas condenser	See description of wet scrubbing/flue-gas condenser in Section 8.4
c.	Selective catalytic reduction (SCR)	See description in Section 8.3. The SCR system is adapted and larger than an SCR system only used for NO_X reduction	See applicability in BAT 20 and in BAT 24
