Reduction in resource consumption by process modifications in cotton wet processes

The textile sector is one of the most important industrial sectors in Turkey. It comprises several sub-sectors among which cotton is the most important. Processes in the cotton textile industry can be dry and wet. A series of cleaner production (CP) options mostly related to water and energy conservation were identified in a selected enterprise focusing on the reduction of water consumption in the regeneration process, water and chemical savings in the dyeing process, heat recovery from the blowdown which was discharged into the waste water treatment plant, and also heat recovery of process waste water. The results of the calculations made during the feasibility stage proved that these CP options were worth implementing in the company being studied.
