Newsletter 15th July 2025

Welcome

This is the nineth edition of our scientific newsletter, dedicated to providing the latest updates on research, regulatory developments, technology, and standard methods in the leather industry.

NOTE: This newsletter is in English, Spanish and Portuguese. One version after the other.

In this issue, we feature an interview with Mr. João Carlos Graeff, a tanner, and Sales Manager for TANAC in Montenegro, RS, Brazil.

It is a great honor for IULTCS to have the collaboration of Mr. Graeff in a very important chemical for the leather manufacture: the extracts of Acacia used in the leather industry for both tannage and retannage of several types of leathers. The tannins from plants represent great value as being a renewable and biobasedchemical that produce compostable leather.

We appreciate Mr. Graeff’s collaboration with IULTCS’ Newsletter.

Please share your comments and suggestions to secretary@iultcs.org

Kind regards,

Dr. Luis A. Zugno, edito
