Tannage Résumé : Historically, chrome tanning has been regarded as a highly polluting tanning method and the environmental negatives of this process have been well documented. Many alternatives have been introduced and adapted over the years to replace our industry's reliance on chrome, but recent developments and pcoresses are now thought to have other environmentally negative effects, so it seems we are almost back to square one. What if it were possible to make chrome tanning much less harmful to the environment ? What are the issues with chrome that have caused it to lose popularity over the years ? The problem have been primarily associated with the high volume of chrome remaining in effluent, and the difficulties and costs associated with getting the residual chrome out of sludge and waste water before chrome III oxidises to become the very toxic chrome VI.
