Kemira to talk up Tanfor T at Tanning Tech
20/09/2012
With a focus on water-intensive industries, Helsinki-based Kemira aims to help its customers improve their consumption of water, energy and raw materials.
It says Tanfor T is a tanning system that produces “perfectly white leather meeting all requirements for shoes, automotive, upholstery and garments”. In addition, it says the system is free of chromium and aldehydes and is based on chemicals that improve the environment thanks to their capacity for treating water.
Tanfor T will also decrease the costs of solid and liquid waste streams from tanneries, Kemira has said. The small amount of the tanning agents left in the tanning bath poses no threat to the environment, it said, citing tests carried out at the Escuela de Ingeniería de Igualada near Barcelona that have shown the chemical oxygen demand (COD) of the tanning bath with Tanfor T to be three times lower than with chromium wastewater and up to 10 times lower than with traditional wet white.
