Sustainable Development
Sustainable Development was originally definedby the Brundt land Commission in 1987 as
Meeting the needs of the present generation, without compromising the ability of future generations tomeet their needs .

Sustainable Development
This definition usually comes with the footnote that itencompasses environmental, economic as well associal needsIn this context industry has the dual role ofsupporting and counteracting sustainabledevelopment at the same time
Support is provided by industry through its role aseconomic motor, employer, provider of infrastructure,supporter of education, health care etc.

SUSTAINABILITY
Need to believe in environmentalsustainability taking incremental steps in
supply chain processes to make it happenNeed to be aware about the social,economical and ecological benefits ofenvironmentally sustainable products anddevelopment processes.

Wet processing
Important environmental concerns relatedto textile wet processing:Chemical intensive wet processing scouring,
bleaching, mercerizing, dyeing , printing etc.Heavy metals iron, copper, lead etc, found indyestuffs auxiliaries, binders etc.Residual dyestuffs, chemicals in water: due to
poor fixation of colors.PVC and phthalates: used in plastisol printingpaste.Formaldehyde : found in dispersing agents,
printing paste and colorant fixatives.

Sustainable Processing of Textiles
Exp lor e in to Bio P roc ess ing of T ex tilesB io-processing can simply be defined as the
application of living organisms and their componentsto industrial products and processes, which aremainly based on enzymes.B io processing also offers the potential for new
industrial processes that require less energy, lesswater and less effluent problems with effective
results.Enzymatic DesizingEnzymatic ScouringEnzymatic B leachingB io polishing and Enzyme based softeners etc.
