Environment Management in TextileIndustry - Web course

COURSE OUTLINE

Definition of ecology and ecological balance, waste and pollutant;Environmental management and role of textile industry; International and Indianlegislation and enforcing agencies in pollution control.

Sequential and integrated waste management approaches; Environmentalimpact along the textile chain from fibre production to disposal, toxicity ofintermediates, dyes and other auxiliaries.

Pollution load from different wet processing operations i.e; preparatory, dyeing,printing, and finishing; Textile effluents and their characterisation, pollutioncontrol monitoring parameters, Technology and principles of effluent treatment -primary, secondary, tertiary.

Advanced colour removal technologies, Recovery and reuse of water andchemicals ; Air and noise pollution and its control ; Eco-labelling schemes,Criteria and permissible limits, Analytical testing of eco and environmentalparameters.

Eco friendly textile processing and waste minimisation- process modification;low liquor techniques, advanced textile processing techniques like Plasma , safe& ecofriendly dyes and auxiliaries, organic cotton , natural dyes, naturallycoloured cotton ,Solid (fibre & polymer waste) recycling - direct extrusion,densification, recovery of monomers ,energy recovery and chemical modificationof fibre waste.

Environmental Management Systems - ISO 14000, certification and criteria,Industrial hygiene and safe working practices, Concept of carbon footprints.
