Indicative levels for specific water consumption The indicative environmental performance levels related to specific water consumption refer to yearly averages calculated using the following equation:
specific water consumption ¼
water consumption rate activity rate
where: water consump­ tion rate:
total annual amount of water consumed by a given process (e.g. bleaching) including water used for washing and rinsing the textile materials and for cleaning the equipment, minus the water reused and/or recycled to the process, expressed in m3/year;
activity rate:
total annual amount of textile materials treated in a given process (e.g. bleaching), expressed in t/year.
Specific wool grease recovery level associated with the best available techniques The environmental performance level related to specific wool grease recovery refers to a yearly average calculated using the following equation:
specific wool grease recovery ¼
rate of wool grease recovered activity rate
rate of wool grease recovered:
total annual amount of wool grease recovered from the pre-treatment of raw wool fibres by scouring, expressed in kg/year;
activity rate:
total annual amount of raw wool fibres pre-treated by scouring, expressed in t/year.
where:
Caustic soda recovery level associated with the best available techniques The environmental performance level related to caustic soda recovery refers to a yearly average calculated using the following equation:
caustic soda recovery ¼
rate of caustic soda recovered rate of caustic soda before recovery
where: rate of caustic soda recovered:
total annual amount of caustic soda recovered from spent mercerisation rinsing water, expressed in kg/year;
rate of caustic soda before re­ covery:
total annual amount of caustic soda in the spent mercerisation rinsing water, expressed in kg/year.

Overall environmental performance
BAT 1.
In order to improve the overall environmental performance, BAT is to elaborate and implement an environmental management system (EMS) that incorporates all of the following features: i.
commitment, leadership, and accountability of the management, including senior management, for the implementation of an effective EMS;
