# Commission Implementing Decision of 26 September 2014 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of pulp, paper and board (notified under document C(2014) 6750) (Text with EEA relevance) (2014/687/EU), Division BAT 3: In order to reduce the release of not readily biodegradable organic chelating agents such as EDTA or DTPA from peroxide bleaching, BAT is to use a combination of the techniques given below.

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

Technique
Applicability
a
Determination of quantity of chelating agents released to the environment through periodic measurements
Not applicable for mills that do not use chelating agents
b
Process optimisation to reduce consumption and emission of not readily biodegradable chelating agents
Not applicable for plants that eliminate 70 % or more of EDTA/DTPA in their waste water treatment plant or process
c
Preferential use of biodegradable or eliminable chelating agents, gradually phasing out non-degradable products
Applicability depends on the availability of appropriate substitutes (biodegradable agents meeting e.g. brightness requirements of pulp)
