In China, from 1 April 2023 it will be possible to recycle leather solid waste containing chromium

This is confirmed by the industry association on the Official Website of China Leather Industry Association (CLIA), Beijing, China. The decision was taken following the "Risk Assessment Report on Hazardous Properties of Leather Scrape Containing Chromium, Transportation and its Utilization", a report that certified the low chromium content of the tannery's solid residues. Hence, the implementation of environmental standards approved by the MEE (Ministry of Ecological Environment), which will come into force from April 1, 2023.

China, study for the removal of Cr(VI) by biochar

Chromium is widely present in the leather processing process, but it should only be the trivalent one, less harmful to humans and the environment. However, it is sometimes found as a production residue resulting from the treatment of sludge produced from tannery waste. A study on the thermochemical decomposition of oily sludge experiments with how to mitigate pollution and obtain charcoal-like substance known as Biochar, which can improve carbon sequestration and soil fertility.  [Removal of Cr(VI) by biochar derived via co-pyrolysis of oily ... - Nature]
