Scientists over at Kemira, a chemical industry group, have developed a new, sustainable, chrome-free tanning system. Tanfor T is free of chromium, aldehydes, and other agents that create unwanted and expensive side-effects for tanners. It’s safe for humans and the environment and will reduce the cost of both solid and liquid waste. A high portion of Tanfor T fixes itself in the leather and what’s left of it in the bath poses no threat to the environment. It also outperforms traditional tanning systems when it comes to dyeability and only requires small adjustments to the traditional production process. Tanfor T is based on aluminum, silicates, and short chain organic acids. It offers a perfect dyeability and high dye affinity, which essentially means that it can be dyed to any color.
