Cleaner production assessment studies were carried out according to the Integrated Pollution Prevention
and Control and Industrial Emission Directive in a cotton/polyester fabric finishing-dyeing textile mill,
located in Denizli, Turkey. Following detailed on-site process evaluation, environmental performance of
the mill was evaluated. Data of the material flow and the energy consumption in all processes was collected.
Mass-energy balances and specific input and output values based on the production processes were calculated.
Also, a chemical inventory list was prepared and all material safety data sheets were collected. Environmental
performance of the mill was benchmarked against similar textile mills in the literature. 92 Best Available
Techniques options were listed. Each suggested BAT option was discussed with the mill management in terms of
techno-economic applicability and implementation of 22 Best Available Techniques were decided. In the decision-making
process, statistical Multi-criteria Decision-Making Methods (Simple Ranking Method, Weighting Criteria Method,
and Weighted Sum Method) were used. Moreover, technical and environmental performances, potential benefits and
savings were determined with the implementation of identified 22 Best Available Techniques such as good management
practices, water and energy consumption optimization-minimization techniques, chemical consumption optimization
and substitution. These evaluations have revealed that after the implementation of suggested 22 Best Available
Techniques, following reductions could be achieved if those techniques were implemented in the future: 43-51%
water consumption, 11-26% energy consumption, 16-39% chemical consumption, 42-52% wastewater flowrate, 26-48%
chemical oxygen demand load, 12-32% waste flue gas emissions, and 8-18% solid waste generation. Payback periods
of the suggested Best Available Techniques were estimated as 1-26 months.
