It takes one pound of chemical fertilizers and pesticides to

conventionally grow the three pounds of cotton needed to

make a T-shirt and a pair of jeans.

beneath cotton's natural fiber lies a long chain of chemically-intensive, "unnatural"

processes. 

To bring this delicate plant to harvest, it is heavily sprayed - 8 to 10 times a season -

with pesticides so poisonous

they gradually render fields barren.  And that's just the beginning. 

To create finished goods, fabrics are often colored with toxic dyes and finished with

formaldehyde.  

Need for organic cotton

Organic food now symbolizes the highest and freshest quality available.

Suppliers of organic cotton are not far behind. 

If we are really concerned about environmental issues today,

our ideas of excellent product design must include impact on the earth.

Organic cotton certification

INTERNATIONAL FEDERATION FOR ORGANIC AGRICULTURE MOVEMENT [IFOAM]

has formulated standards and guidelines for

organic cotton cultivation and are

followed by many labelling agencies to certify

organic cotton and other farm produce.

Merits of organic cotton cultivation

Environmentally Friendly Technology

Reduction in Cost of Cultivation

Management of Insecticide Resistance

Organic cotton in IndiaFive to seven decades ago, most of the cotton cultivated in the country was ‘eco-friendly’ with little or no use of toxic

chemicals in its production.

Even today, there are many pockets in India, where it is produced without the use of agrochemicals, e.g.,

areas growing Wagad cotton in Gujarat, Y-1 desi cotton of Khandesh region of Maharashtra,

Maljari in Madhya Pradesh,

part of areas growing Jayadhar and Suyodhar in Karnataka

Nandicum in Andhra Pradesh and

parts of cotton areas in north eastern hill region.

Sally Fox introduced to colored cotton while working

for a cotton breeder, whose focus was developing pest-

resistant strains of cotton.

The peoples of Central and South America had spun

these strains for centuries, but the fiber qualities were

not sufficient for modern machine spinning.

Sally Fox in 1982 took on the challenge of improving an ancient agricultural art.

Fox successfully bred and marketed varieties of naturally coloured cotton she calls FoxFiber ®.

Today, Sally Fox designs fabrics with her cotton and continues research.

Fox has received a patent and three Plant Variety Protection Certificates for her naturally colored cottons which, in addition to browns, she now grows in reds and greens.

Her invention has been so popular it has sprouted two successful companies -- Vreseis, Ltd. and Natural Cotton Colours, both operating in Arizona.

ECO LABELS

Eco-labels are product labels that

inform consumers about the environmental impact of a

product. They encourage producers to switch to environmentally sound production

process methods (PPMs) for advantage in the marketplace. Eco-labels allow producers to

differentiate their products from products that are less

environmentally friendly and

thus to reach environmentally conscious consumers. 

ECO LABEL CRITERIA

ENVIRONMENT FRIENDLINESS OF THE ENTIRE LIFE CYCLE OF THE PRODUCT

CRADLE TO GRAVE ASSESSMENT

1. Production of raw materials

2. Production of the end product

3. Packaging and transport of raw

materials and the finished product

4. Use of the product by companies and

consumers

5. Disposal of the product

e.g. assessment of a T-shirt starts in the

cotton field and ends in the incineration

plant.

ECO LABEL CRITERIA

•As little use as possible of chemical substances harmful to the environment

•No or very few heavy metals in the product

•Energy conservation during production and use

•The lowest possible amounts of harmful

substances in wastewater

•Requirements which ensure that the product works well and will last long
