European Union& / #8217 / s Integrated Pollution Prevention and Control (IPPC) Directive forms a comprehensive framework for industries mentioned in the Annex 1 of the Directive concentrating on the reduction of the environmental impacts of the industrial activities which can be implemented by the BREF Documents that provide guidelines for each sector. Among those industries, textile is a water and energy intensive one. In the present study, gains in terms of energy and water consumptions were assessed in a denim producing textile mill following the adaptation of related BAT measures. In this respect, installation of flow meters, use of semi-counter current rinsing applications / minimization of wash waters in the water softening plant, reuse of concentrate stream from reverse osmosis plant and compressor cooling waters resulted in reduction from 6,000 to 4,850 tone/day of total water consumption in the period of January& / #8217 / 05-December& / #8217 / 07. Consequently, specific water consumption in the mill was decreased from 78 to 55 L/kg textile by 29:5% which is close to lower limit of the range suggested in BREF Textile Document (i.e. 50-100 L/kg fabric). Use of waste heat from finishing wastewater streams in heating up the washing waters, heat-insulation and maintenance applications in addition to BAT measures taken for water minimization reduced specific energy consumption from 0.0100 to 0.0091 Gcal/kg textile resulting in 9% reduction in the period of January& / #8217 / 05-December& / #8217 / 07, although, energy consumption was increased from 786 to 804 Gcal/day. This achieved level of specific energy consumption was in the reference range mentioned in BREF Textile Document (i.e. 8-20 kWh/kg fabric).
