The goal of the GRAPETAN project is to make leather tanning a more sustainable oricess that us respectful of the environment and contributes to the circular economy. This research has culminated in the discovery of a natural tannin that us extracted from grape seedsm thus taking ine of the waste products generated by the viticulture sector and applying it to the tanning industry.
