Anatomy of a jacket: how Kathmandu is rethinking sustainable clothing | Kathmandu: Sustainable future
Winter season, as they say, is coming. If you are hunting for a puffer jacket to hold on your own warm with a lighter effect on the surroundings, the workforce at Kathmandu has been functioning tough. The New Zealand-started, certified B-Corp outdoor dress in company a short while ago introduced its NXT-Stage BioDown jacket, an revolutionary and award-winning piece of clothing produced from a highly resilient, biodegradable nylon.
Whilst most jackets are made from polyester, Kathmandu selected nylon for its increased toughness. It also determined to decide for nylon 66 (typically applied in friction bearings, carpets and luggage), a more robust variation of its near cousin, nylon 6 (assume toothbrush bristles) so that it will previous – and be worn – more time.
Kathmandu’s researchers tweaked the polymer with a new component created to induce biodegradation in an oxygen-totally free landfill surroundings. In a nutshell, the component makes the discarded jacket entice microbes that sort a biofilm on the product to support them split down all those lengthy chains of polymers. (But do not get worried, your jacket won’t commence slipping apart in the clean or although you are going for walks the canine in the rain – only when it reaches oxygen-no cost landfill.*)
Hang on, is not nylon derived from fossil gasoline? Perfectly, sure. Kathmandu’s Californian-born normal supervisor of item, Robert Fry, suggests the choice to use nylon is all about actively playing the extensive recreation: making a higher-top quality garment that will previous for a longer time, be far more recyclable when technologies catches up, and, in the meantime, biodegrade in three to 5 years beneath the right situations.*
“For us, the extensive-phrase objectives about sustainability have to do with circularity far more than nearly anything else,” Fry says from the company’s Christchurch headquarters. “And there are lots of principles of circularity, all of which we’re seriously invested in supporting, discovering, establishing and innovating all-around, and they are all in many states of go.”
The dilemma Kathmandu faces is that considerably of the infrastructure essential to close those round programs is not broadly available in Australia still. For instance, we are even now a long way away from widespread textile-to-textile chemical recycling, and the styles of anaerobic, or oxygen-cost-free, landfills essential to make BioDown’s ground breaking product biodegrade properly are sparse.
The hope is that demand will ignite supply. “We’re undertaking our part to energise that infrastructure, so that as we introduce new products, new concepts into the marketplace, that there’s an infrastructure in place that we can lover with, plug into and collaborate with,” Fry claims.
So, following you’ve worn your jacket for a long time, how does the breakdown of the material sooner or later materialize?
Manu Rastogi, who heads Kathmandu’s innovation staff and labored intently on the BioDown design and style, claims: “Biodegradation takes place at the molecular amount. Nylon 66 is produced of carbon, hydrogen, oxygen and nitrogen. Microbes split down all those molecular chains, irrespective of whether that occurs around hundreds of yrs or a number of several years, as in the situation of BioDown. As the nylon is consumed by microbes, they launch carbon dioxide and methane, and all that stays at the close is in essence microbial poop.”
Rastogi and his group went in look for of greatest-apply landfills and located additional than 20 biologically lively web sites in New Zealand. Despite the fact that there are bioreactor landfills in Australia, our sizing and procedure of state governments means they are not well documented, Rastogi suggests. There’s room for advancement.
Every single point out and territory also manages and prioritises waste otherwise. In suburban Sydney, roughly 40% of waste goes to Veolia’s Woodlawn Eco Precinct, an modern, contemporary landfill facility that contains the essential bioreactor landfill.
“And if you glimpse at what’s going on globally,” Rastogi claims, “that’s wherever the landfill design and engineering is heading: toward ‘how do we harness carbon dioxide and methane and use that strength to make electric power, so it does not go out in the ambiance as greenhouse gases?’”
Adopting the “build it and they will come” philosophy, Rastogi’s crew intended the jacket to be as recyclable as possible, too, earning the zippers and internal lining from the similar material. Insulating the jacket are duck down and feathers certified to the Liable Down Common, the international standard for guaranteeing finest methods in animal welfare through the retail offer chain. And, by scanning in a QR code on the solution, shoppers can trace the important disorders and resource of the down in their jacket via the web page Monitor My Down.
Other biodegradable, environmentally helpful specifics contain labels built of cotton, dangle tags manufactured out of paper in its place of plastic, and applying all-natural bentonite clay alternatively of silica gel to soak up humidity in the course of transport.
In an imperfect entire world, it is continue to critical for people and makers to perform their role and hold striving for a circular financial state.
Fry claims: “We have to be responsible citizens of the world and of our respective nations. It’s morally incumbent on us to do our very best to make the globe a much better location. As Manu likes to say, ‘we want to get from a area of performing less bad to carrying out more good’.”
Granted, the fully circular economic climate may possibly be a even though off but, but it is encouraging to see at the very least a single corporation developing finish-of-existence responsibilities into its products and solutions from the incredibly commencing.

*Tests less than ASTM D5511 signifies biodegradation of 86.6% right after 3 decades could arise in optimum situations in some biologically active landfills without having oxygen. Be sure to check with your nearby council if this form of selection or waste disposal facilities exist for the products.
