# Commission Implementing Decision of 26 March 2013 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the production of cement, lime and magnesium oxide (notified under document C(2013) 1728) (Text with EEA relevance) (2013/163/EU), Division 27

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

In order to prevent emissions of PCDD/F or to keep the emissions of PCDD/F from the flue-gases of the kiln firing processes low, BAT is to use one or a combination of the following techniques:
Technique
Applicability
a
Carefully selecting and controlling of kiln inputs (raw materials), i.e. chlorine, copper and volatile organic compounds
Generally applicable
b
Carefully selecting and controlling kiln inputs (fuels), i.e. chlorine and copper
Generally applicable
c
Limiting/avoiding the use of wastes which contain chlorinated organic materials
Generally applicable
d
Avoid feeding fuels with a high content of halogens (e.g. chlorine) in secondary firing
Generally applicable
e
Quick cooling of kiln flue-gases to lower than 200 °C and minimising residence time of flue-gases and oxygen content in zones where the temperatures range between 300 and 450 °C
Applicable to long wet kilns and long dry kilns without preheating. In modern preheater and precalciner kilns, this feature is already inherent
f
Stop co-incinerating waste for operations such as start-ups and/or shutdowns
Generally applicable
