This document discusses sustainability in the apparel industry. It defines sustainability as meeting present needs without compromising future generations' ability to meet their own needs. The apparel industry uses large amounts of resources and chemicals that harm the environment. The document recommends more sustainable practices like using organic cotton and recycling textiles. It provides examples of companies like Levi's and Nike that are developing sustainable apparel lines using recycled materials and reducing water and waste.

3. SUSTAINABILITY- DEFINITION
• Sustain means “to maintain” or “to uphold” .
• “To improve the quality of life while living
within the carrying capacity of ecosystems”
IUCN (The World Conservation Union), 1991.ss
The 3 principles of sustainability
• Environmentally Viable- It should have the
lowest possible adverse effect on the
environment.
• Social Desirable- It should respect the social
elements of fair trade and human rights of the
people involved.
• Economically feasible- It should be able to
Compete effectively in the global marketplace
against less sustainable products.

4. NEED OF SUSTAINABILITY IN APPAREL
INDUSTRY
• Consumption of natural resources has increased
dramatically in the last 40 years
• Issues like that of global warming, natural resource
depletion, toxic waste disposal, and increasing air, water
and soil pollution are of global importance.
• At every stage of textile production, vast amounts of
energy, clean water and chemicals are used to process the
textiles and apparel.
• Thus apparel industry also needs to eliminate
environmental hazards, improve process efficiency.
4

5. A sustainable approach covers the following points:
• Minimum use of resources (water and energy
consumption during preparation, colouration and
finishing).
• Minimum chemical consumption.
• Minimum pollution load.
• Toxic chemicals eliminated from supply chain.
• Harmful chemical residues eliminated from final
textile.

8. ACHEIVING SUSTAINABILITY IN APPAREL
INDUSTRY
In broader perspective sustainability can be
achieved by following 2 major steps-
1. Organic Clothing
It is made from materials raised in or grown in
compliance with organic agricultural standards.
The source of the clothing's fibre are free from
herbicides, pesticides, or genetically modified
seeds.
2. Recycling Fashion
Textiles that are discarded by consumers,
retailers or charitable organisations undergo a
discriminating process of sorting, grading and
separation into waste-free products which are
suitable for reuse.

9. BENEFITS OF ORGANIC CLOTHING
• No chemical pesticides are used.
• Organic cotton farming produces far less CO2
emissions.
• Organic cotton farming uses up to 60% less water than
conventional farming methods.
• Pesticide or herbicide residues are not entered
accidentally into the environment.
• Humans and animals are not exposed to chemical
pesticides or herbicides.
• When the fabric is discarded, pesticides and herbicides
are not returned to the earth in landfill, or enter
into recycling process.

10. STEPS TO BE TAKEN FOR SUSTAINABLE
TEXTILE PROCESSING
1. Eco-friendly Fibres
• Organic cotton
• Bamboo Fibre
• Alpaca Wool
• Recycled Polyester
2. Dyes
• Azo-free colourants
• Biodegradable dyes
• Chrome-free tanning
• Fibre reactive dyes
• Low-impact dyes
• Natural dyes
Organic cotton
Yarn spun from
alpaca wool
Bamboo fibre
Bales of PET bottles

11. ALTERNATE WET PROCESSING METHODS
• Chlorine-free bleaching
• Cold or low temperature dye processes
• Dye bath reuse
• Eco bleach
• Ink-jet printing
• Vegetable tanning
• Waste water recycling

12. EXAMPLES OF SUSTAINABILITY IN APPAREL
INDUSTRY
Levi’s
• Levi's is a brand of denim jeans, under privately held American
clothing company Levi Strauss & Co.
• TheirWaste<Less line of jeans uses cleaned, sorted and crushed PET plastic
bottles and food trays to make polyester fiber.
• Then its blended with cotton and woven.
12

13. WATER<LESS™JEANS THAT SAVES WATER
• Levi’s also designed the Water<Less
range, which uses less water in the
finishing stage in 2010.

14. Nike, Inc.
• Nike's Trash Talk Shoe, which had
been constructed in February 2008
from pieces of leather and synthetic
leather waste from factory floors.
• Its sole is composed of ground-up
rubber from a shoe recycling program
• NIKE Flyknit, introduced in 2012, The
technology uses knit construction that
allows for a lightweight upper that
reduces footwear waste.
• The Flyknit Lunar 1+ running shoe
reduces footwear waste by 80% on
average when compared to typical
NIKE running footwear.

15. CONCLUSION
The measurement and control of these inputs and
outputs can lead to
• Improved resource productivity.
• Improved co-efficiency.
• Improved cost efficiency.
• Improved customer satisfaction.
• Improved brand reputation.
• Improved environmental conditions.
• Better health conditions of the wearers and the
workers.
