In 2013, a workforce of Cambridge University scientists had been in Nepal’s Kathmandu Valley, growing a machine to measure pollution within the area’s waters.

The scientists spoke to local people, who relied on the filthy streams and rivers for his or her water supply, and realized that waste from textile factories was contaminating the waterways.

“We were shocked,” says Orr Yarkoni, one of the researchers on the expedition.

The scientists analyzed the water and their findings aligned with what the locals said — most of the hazardous chemical substances got here from the textile business.

Nepal is one of the most water-abundant international locations on the earth, but water pollution is a main problem. More than 85% of the inhabitants would not have entry to protected ingesting water.

“That feeling of ‘I have no safe water to drink’ is something that no human should have to feel in this day and age,” says Yarkoni.

“When we realized that so much of the pollution comes from something as simple as putting color into our clothes, we thought ‘there has to be a better way,'” he says.

Three years later, that pondering spurred Yarkoni and two Cambridge University colleagues, Jim Ajioka and David Nugent, to co-found Colorifix and develop a new manner to dye garments that won’t hurt the planet. Yarkoni claims the expertise they have developed eliminates the need for poisonous chemical substances. It also makes use of up to 90% much less water and up to 40% much less power than the traditional dyeing course of, he says.

The shade purple

For millennia, people used pure dyes to shade materials.

Then in 1856, chemist William Henry Perkin had a serendipitous accident.

Perkin was making an attempt to produce quinine, a substance used to deal with malaria, when he inadvertently created the first artificial dye — a vivid purple substance which simply transferred onto fabric.

The purple dye opened a floodgate of artificial shade prospects that revolutionized the world of vogue. But with it got here a torrent of environmental issues.

Today, the dyeing business makes use of more than 8,000 chemical substances. Many, together with sulfur, arsenic and formaldehyde, are dangerous to wildlife and human well being.

In much less developed Asian international locations, which produce a large share of the world’s garments, weak regulation enforcement signifies that many textile producers dump poisonous substances instantly into local waterways. And it is occurring on a huge scale — the dyeing course of makes use of sufficient water to fill 2 million Olympic-sized swimming swimming pools every year. This makes the dyeing business one of essentially the most environmentally dangerous on the earth, responsible for up to one fifth of industrial water pollution.

Finding microscopic options

The machine Orr and his workforce developed to check water pollution in Nepal used genetically modified bacteria that modified shade when uncovered to hazardous chemical substances.

He and his business companions determined to harness the bacteria’s color-changing capability to develop their dyeing innovation.

Colorifix — based mostly in Norwich, within the east of England — produces dyes which might be impressed by “nature’s blueprints.” But the expertise would not derive pigments straight from crops or animals, like conventional pure dyeing strategies. Instead, it copies nature’s processes in a lab setting, by replicating the “DNA message” that codes for shade in an organism.

Yarkoni says Colorifix has made pigments utilizing genetic code taken from crops, dragonflies and gorillas, amongst others, utilizing DNA information sourced from scientific research. “We don’t like bothering animals,” he provides.

Colorifix inserts the genetic information that directs the color-making course of into a bacterial cell, which copies itself each 25 minutes. The bacteria are fed with sugar molasses and nitrogen — by-products of the agricultural business — in a fermenting machine, the place the cells multiply in number, every making more pigment.

Yarkoni likens the fermentation course of to making beer, “but instead of making alcohol, we’re making the pigments.”

While the conventional industry mixes primary colors to create a range of shades, Yarkoni says Colorifix makes "true" pigments.

A rising motion

Colorifix is not the one company utilizing biotechnology to create sustainable shades. German-Israeli agency Algalife is rising non-toxic dyes with algae. French startup Pili makes use of a related fermentation course of to Colorifix to make shade. CEO Jeremie Blache says that Pili’s course of, although nonetheless on the trial stage, is projected to use 80% much less water and produce 90% much less carbon emissions, than standard dye-making strategies.

However, Yarkoni claims Colorifix is the one biotechnology startup that goals to rework dye manufacturing and software.

While different bacteria-based dye improvements rely on huge quantities of water and chemical substances to isolate pigments from bacteria, and make and apply the dye, Colorifix places the bacteria straight onto the material to shade it. The cloth is heated, inflicting the microorganisms’ membranes to burst and release the colour, which chemically attaches to the fiber. The remnants of bacteria cells are then washed off — but the colour remains.

Flying colours

Yarkoni says that an added profit of his expertise is that it cuts down on transport pollution — one issue behind the style business’s enormous carbon footprint.

Rather than transporting large portions of dye, Colorifix can send simply 5 grams of color-packed bacteria to a dyehouse. Orr claims the microorganism will multiply and that after 10 days, the manufacturing facility can be ready to produce 50 tonnes of dye answer a day.

But this “grow your own” method has drawbacks; dyehouses will need to buy fermenting tools and obtain coaching from Colorifix to undertake the method in-house.

Pili’s Blache argues that if dyehouses can merely buy ready-to-use pigments, they’re more possible to make the swap to sustainable dyes.

Georgia Parker, Innovation Manager at startup accelerator Fashion for Good, says that transporting live microbes safely is one other hurdle.

“There is particular legislation around the transportation of living organisms across different geographies,” Parker says. “As a dyehouse, you would need to get government signoff to import these organisms.”

Despite the limitations, Parker anticipates that bacteria-based dyes will change into cost efficient within the long run and can be used more broadly within the business “in the next couple years.”

Beyond greenwashing

Colorifix is already in excessive demand: Yarkoni says the startup has more clients than it can handle, and has attracted support from manufacturers together with H&M. The Swedish vogue giant invested within the company in 2018 and continues to pilot the expertise inside its supply chain.

H&M is one of a number of quick vogue manufacturers adopting bold goals to scale back their environmental and chemical footprint. Francois Souchet, who leads the Ellen Macarthur Foundation’s Make Fashion Circular initiative, says that “increased scrutiny from policymakers” and “expectations from the consumer for better solutions” are pushing the business to change into more sustainable.

While it is early days for Colorifix — the company launched its first industrial trial at a dyehouse in Portugal last month — Yarkoni says he is assured that bioengineering options will help set the style business on a greener path.

“I truly believe that in the future, a very large proportion of our industry — if not all of it — will be based on these biological principles.”
