Exploring the feasibility of substituting mimosa tannin for pine bark powder. A LCA perspective

The use of vegetable tannins is a bio-based alternative to chrome tanning. most used extracts are Mimosa and Quebracho. To improve the sustainability tanning process, chemically unmodified pine bark could be as natural source tannins. present study was aimed evaluate environmental impact powder obtain leather through life cycle assessment. Specifically, evaluation performed for both: i) tannin atomized mimosa extract production raw material; ii) process tanned with versus extract. An eco-friendly cleaner method obtaining developed. This new allows reduction in 83% “climate change” category. However, when this applied leather, shows an increase all studied categories compared
