How does denim industry impact negatively on environment?


A report released by National Geography that says 11,000 liters water is used to produce one pair Jeans from raw material production to denim finishing process. Denim production consumes huge amount of energy and hazardous chemicals which causes great health issues of denim workers. 

Dyeing of yarns for denim fabric production discharges huge amount of colored water into the adjacent water bodies. Report says, some of rivers water color in Mexco turns into blue that causes threat to the plant of the deep water as they need sunlight which is hindered by the blue color of water.

The latest innovations that go soft on the environment include dyeing methods that save water and energy and result in less waste. Contemporary denim manufacturers use comparatively eco-friendly concentrated sulphur dyes. The chemical structure of sulphur dyes helps them to bond better with cotton. This method does not involve rinsing. Instead, the dye is oxidised with effective fixing agents to make it stay on the denim. In contrast to conventional indigo dyeing, this method saves approximately 92 per cent of water, 87 per cent of cotton waste and 30 per cent of energy. More enzymes are used in the denim finishing process. This process not only improves the final product, it also results in less energy consumption and less pollution.

On July 16, The Ellen MacArthur Foundation, a nonprofit focused on the circular economy and sustainable practices, released a set of guidelines called the "Jeans Redesign," which strives to address waste within the denim industry by setting minimum requirements around materials, durability and more.

Some of the reputed big brands are considering their denim production in a environmental friendly way. Recently, Wrangler, Madewell and Gap signing on to participate in the foundation's call for more sustainable denim. Wrangler is working to reduce the energy required to dye its denim products, Madewell released a line of fair trade-certified denim, and Gap is working to achieve 100% sustainably-sourced cotton for its denim items by 2025.

Swedish retail giant H&M also launched jeans made from recycled, donated clothing. This range of denim utilises 20 per cent recycled cotton, which is the uppermost limit that can be used without impacting the quality of the finished product.

Another Swedish brand KappAhl has announced they are selling 100% sustainable denims since Fall Winter 2019 and it is continuing by following seasons also.

0he brand has also launched denim made from plastic bottles. Swedish label Nudie jeans has also launched post-recycled denim rugs. The brand also uses 100 per cent organic fabric to produce variety of denim articles like jeans, bags, shirts, et al. The zero water technology, ozone processing for lighter shades, laser wash that uses no water at all and increased use of less toxic chemicals in denim, are some of the ways in which denim is transforming into a green industry.  

The denim brand Boyish has a top-to-bottom sustainability model, including a manufacturing process that uses one-third the typical amount of water in production—all of which is then recycled and reused. 

Laura Alexander, the founder of sustainable marketplace Brightly, says it is good that big brands started to get on board with more eco-friendly practices around denim, but that part of the responsibility falls on the consumer. So consumer needs to support and purchase from the brands who is paying more to takes sustainable denim into the market and keep a sustainable footprint. Let kick the fast fashion trend and take your cloths considering circular fashion economy to keep the world green for next generation.
