Wet white tanning refers to organic tanning methods. The biosynthetics used to tan the leather, which result in a semi-finished leather that looks white-tinted.
This fairly new method of tanning has been gaining popularity, partially due to increased concern for water treatment systems and the environment.
Wet Blue is the tanning process where chromes are used to process the leather from raw hide to finished leathers. This process causes the semi-finished leather to look blue-tinted.
The off-cuts from wet white tanned leather in the form of shavings can be recycled or used as fertiliser, in contrast to wet blue tanning methods.
