Tanning

The Tanning Production Stage covers the beamhouse processing and initial tanning (but does not include drying, dyeing,or finishing unless otherwise noted). All Leather Example Materials share several common Tanning process options. The plant-based materials category has no process options for this Production Stage, as all impacts are included in previous Production Stages.

  • Tanning, chrome process is the default process selection for Tanning and should be used unless another Tanning process is applicable. Chrome tanning uses Chromium (III) compounds and the resulting leather is known as “wet blue.”
  • Tanning, aldehyde process should be selected when the tanning uses aldehyde compounds.This process is considered an alternative to chrome tanning and the resulting leather is known as “wet white.”Other “wet white” processing compounds are possible. If the intermediate leather is considered “wet white,” then the Tanning, aldehyde processis considered to be the most representative proxy.
  • Leather tanning, vegetable should be selected when the tanning is performed using traditional tanning techniques, where tannin compounds are extracted from plants.
