What is "Chrome-free tanning" - Definition & Explanation

Chrome-free tanning is the tanning of hides to create leather either through the use of oils or natural tannins instead of chromium salts. This tanning process is more time intensive than chrome tanning, but is better for the environment, as the chromium method uses chrome, a known carcinogen that can be absorbed through the skin and cause contamination of soil and waterways surrounding tanneries.
