WASTE MINIMISATION IN HOSIERY TEXTILE DYEING – A CASE STUDY

Abstract

This paper deals with the evaluation of waste minimisation options that are implemented in hosiery dyeing units at Tirupur. The evaluation was carried out on technical, environmental and economic aspects in which the production capacity, space requirement and equipment requirement were considered as the criterion for technical aspects, payback period was the criterion for economic aspect and the change in effluent characteristics, reduction in water and power consumption, reusability of waste was the criterion for environmental evaluation. The implementation of several options led to increase in production by 2% to 10%, reduction in water consumption by 2% to 50% and the power consumption by 2% to 67%. The TDS in the effluent was reduced by 35% to 56%. Most of the options do not require any space and investment and the payback calculated for the options are only few months.
