Progress in Decay of utility Intake, Process Time Assimilation and CO2 Emission in Textiles through New Generation Colorants

Textile dyeing effluents containing recalcitrant dyes are polluting waters due to their color and by the formation of toxic or carcinogenic intermediates such as aromatic amines from azo dyes. Since conventional treatment systems based on chemical or physical methods are quite expensive and consume high amounts of chemicals and energy, alternative technologies for this purpose have recently been studied. A number of new generation dyestuffs have been developed at laboratory scale to replace conventional dyestuff. Additionally, new generation dyestuffs shows very promising results for reduction of utilities and chemical consumption. In this contribution, we made a novel approach to detailed onsite investigation on water, steam, electricity and chemical minimization employing high exhaustion-fixation dyestuffs and analysis on production processes performed according to UNFCC clean Development Mechanism (CDM) promotion. Specific consumptions in wet processes were calculated by mass balance analyses. The multi-criteria decision-making methods were employed to determine suitable best available techniques
