In order to reduce the generation of waste water and to reduce water usage, BAT is to use all of the techniques given below.\nTechnique\nDescription\nApplicability\na.\nSegregation of water streams\nLeachate seeping from compost piles and windrows is segregated from surface run-off water (see BAT 19f).\nGenerally applicable to new plants.\nGenerally applicable to existing plants within the constraints associated with the layout of the water circuits.\nb.\nWater recirculation\nRecirculating process water streams (e.g. from dewatering of liquid digestate in anaerobic processes) or using as much as possible other water streams (e.g. water condensate, rinsing water, surface run-off water). The degree of recirculation is limited by the water balance of the plant, the content of impurities (e.g. heavy metals, salts, pathogens, odorous compounds) and/or the characteristics of the water streams (e.g. nutrient content).\nGenerally applicable.\nc.\nMinimisation of the generation of leachate\nOptimising the moisture content of the waste in order to minimise the generation of leachate.\nGenerally applicable.",
