# Commission Implementing Decision (EU) 2018/1147 of 10 August 2018 establishing best available techniques (BAT) conclusions for waste treatment, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2018) 5070) (Text with EEA relevance), Division 4.6.1: Overall environmental performance

Extent: E+W+S+N.I.

BAT 48. In order to improve the overall environmental performance of the thermal treatment of spent activated carbon, waste catalysts and excavated contaminated soil, BAT is to use all of the techniques given below.
Technique
Description
Applicability
a.
Heat recovery from the furnace off-gas
Recovered heat may be used, for example, for preheating of combustion air or for the generation of steam, which is also used in the reactivation of the spent activated carbon.
Generally applicable.
b.
Indirectly fired furnace
An indirectly fired furnace is used to avoid contact between the contents of the furnace and the flue-gases from the burner(s).
Indirectly fired furnaces are normally constructed with a metal tube and applicability may be restricted due to corrosion problems.
There may be also economic restrictions for retrofitting existing plants.
c.
Process-integrated techniques to reduce emissions to air
This includes techniques such as:
control of the furnace temperature and of the rotation speed of the rotary furnace;
choice of fuel;
use of a sealed furnace or operation of the furnace at a reduced pressure to avoid diffuse emissions to air.
Generally applicable.
