Currently, old denim products are dumped in landfills, and dye run-off from denim production can pollute local water supplies.
On an average, the life cycle of a pair of denim jeans produces more than 30 kg of CO2 and uses around 3500 liters of water, the equivalent of running 44 baths.
An unique process called circular denim pulverises used denim into ultrafine particles and then coats or prints the color particles on to undyed new denim to create the typical denim appearance.
This way, the old denim is reused, and new denim does not have to be dyed using the traditional yarn dyeing approach, which consumes a huge amount of water and energy.
If necessary, the color of the fine particles can be enhanced or changed easily before the coating or printing process. This will also help create a new fashion effect for denim products.
This process also allows dye to be reused, minimising water use and effluent discharge.
The circular denim approach is a completely new one, addressing both denim waste and new denim manufacturing at the same time.
More than 450 million denim jeans are sold globally each year and the retail jeans market is estimated to reach 56 billion dollars by next year.
