The water footprint of an individual, community or business is defined as the total volume of freshwater used to produce the goods and services consumed by the individual or community or produced by the business.

Water use is measured in water volume consumed (evaporated) and/or polluted per unit of time. A water footprint can be calculated for any well-defined group of consumers (e.g., an individual, family, village, city, province, state or nation) or producers (e.g., a public organization, private enterprise or economic sector).

“Invention” can be defined as the creation of a product or introduction of a process for the first time. “Innovation” on the other hand, occurs if someone improves on or makes a significant contribution to an existing product, process or service.

1. Institutions – which are often neglected but are where the innovations happen.2. Markets – where the demand and the finance comes from and3. Technologies – which go hand in hand with innovations

“Innovation is about the smart application of knowledge to solve problems more imaginatively than we have in the past.”

Forensic evaluation revealed that the microplastic resembled PES and acrylic fibres used in clothing, mainly those sites which receive sewage effluent

KITL Microplastic- the future

A single garment when washed in a machine can shed >1900 fibres per wash

Designers of clothing and washing machines should consider the need to reduce the release and develop methods to remove microplastic from sewage.

KITL Eco Friendly Garments

• Organic Cotton farming requires 25% less water than traditional cotton.• Bamboo: No pesticides required and the fabric is soft to touch • Lycoell: Solvent is recovered/recycled. It is an alternate to Rayon.• Ingeo: This is a man-made fiber by converting corn into a polymer to

make bio- degradable material. It is breathable and has insulation properties of high-performing synthetic material. Requires 68% less energy than polyester and is biodegradable.

• Hemp: A pound of hemp fiber needs a fraction of water needed for a pound of cotton. It does not require pesticides.

• Soy: Soy fabrics use a by-product of Soy Products, namely Soy Milk, Soybean Oil to create a material with a feel and look similar to silk.

Raw Material

Cotton T-Shirt

Polyester Blouse

Manufacturing Transportation Use

Cotton is cheaper and takes less energy to manufacture than synthetic fibres.But over its lifetime , a cotton T- Shirt requires more than twice the energy than is necessary to manufacture and maintain a polyester blouse. The main difference: polyester garments can be washed at a lower temperature, can hang dry and need no ironing.

Energy used over the life time of the garment, in kilowatt hours.*

Use assumes 25 washes per garment. The cotton T-Shirt is washed at 140 degrees Fahrenheit, followed by tumble-drying and ironing.

The energy of one kilowatt hour will operate a 40-watt light bulb for a full day or a 19” color television for about four hours.

The polyester blouse is washed at 104 degrees Fahrenheit, hung dry and not ironed.

Carbon dioxide is a byproduct of the chemical reaction that creates alcohol, a process that begins wityh grape crushing

Energy used for lights, cooling tanks and pumps all result in carbondioxide emmissions
