Assessment of Biodegradability of Synthetic Tanning Agents Used in Leather Tanning Process AbstractThe goal of this research was to assess the biodegradability of two synthetic tanning agents (syntans), Phenol condensation product and Nitrogen containing resin using Respirometry. The new methods have been. This type of tanning process uses no dangerous chemicals or carcinogens, and it is much easier on the environment than chrome tanning. You can stamp veg tanned leather, carve into it, wet formed it by hand into the shape of a mold cast, or even add grove lines into veg tanned leather, and it retains every bit of intricate detail.
