Greening Leather – More Ways Than One – from TreeHugger.com and Footwear News
Jun11
We’ve written about greening leather tanning practices in the past on the blog. The good news is that this treatment is getting better press across the green world and the best news is that a bunch of our favorite footwear brands are being recognized for making the responsible choice of using greener leather.
There was a recent article on Treehugger.com, referencing an article in Footwear News, about the three ways that tanneries are greening up their processes, and the companies that are supporting these more sustainable and responsible factories.
First off, leather tanneries are some of the worst water polluters in the world. There are so many chemicals used, and there is so much water used, that they not only flush bad chemicals into water sources, but also USE a massive amount of water, which is also wasteful. Simona Tanning, which provides leathers for some of our favorite brands, including Keen, Clarks, Camper, MBT Shoes, Sperry Top-Sider and Timberland is reducing their water usage and their discharge by 40% using reverse osmosis technology.
Second, Treehugger highlighted companies that are incorporating solar power into their energy production. The leather tanning company, PrimeAsia Leather Corp, who supplies New Balance, Clarks, Reebok, The North Face and Merrell cites that it’s highest bill and highest energy consumption comes from heating the water in large boilers for their process and by installing a sizable solar panel installation, they expect their up front solar investment will not only pay for itself in less than 18 months, it will also significantly reduce their carbon footprint!
Finally, and this is what every manufacturing company should do, the ISA Tan Tec leather tannery, who supplies Keen, New Balance, The North Face, Reef, Timberland, Merrell and Chaco is focusing on looking at every step of their process and optimizing and improving their practices. They have invested in a hydraulic cooling system, which uses water at specific temperatures to cool a space. As the water warms from ambient temperature, it is moved from the hydraulic cooling system into the boilers for the tanning process. The pre-warmed water needs less energy to heat, and the hydraulic cooling system has reduced the need for electric powered fans. This smart improvement has reduced energy consumption by 35% and water usage by 50%!

Organic cotton
Organic cotton has a huge variety of benefits. Firstly, organic cotton does use genetic engineering or antibiotics, which means that natural strengths in the plants are cultivated and weaker plants are culled out. Consequently, soil health is improved and species diversity is supported. By protecting the soil and the earth, we’ll have better, healthier land and crops and we’ll be preserving the health and success of future generations.
The only downside to organic cotton is that is costs more to produce, therefore increasing the costs of consumer goods down the line – but using organic cotton not only preserves the environment from chemicals, it also reduces or dependence on oil and petroleum.
