Tannins are astringent polyphenolic compounds that precipitate proteins, alkaloids, and amino acids. These naturally occurring biomolecules are found in certain types of woods and plants such as spices, nuts, and tea. They are also found in grape skins, stems, and seeds. Tannins are scientifically known as polyphenols. Tannin biomolecules are widely present in numerous plants & trees, where they act as pesticides. Tannins also benefit in growth regulation and protection from predation.
“Green” Leather Tanning
Recently, the Central Leather Research Institute (CLRI), a division of the Council for Scientific and Industrial Research (CSIR), developed a biodegradable dispersing agent. It allows chrome tanning of leather using only half the quantity of the standard product. It saved almost 15 million liters water per day in the Indian leather industry alone. This innovative product can save approximately 200 million liters water a day on global scale. This technology is expected to protect the rivers from lethal sulfates and chromium effluents that are mixed in about 170 million liters of water on a daily basis!
Innovation is the Goal
This advanced technology is aimed to benefit such as cost saving, time economy, water conservation, waste management, and reduced process steps. It offers “dry tanning” as a product and another “waterless chrome tanning” method. However, thorough training is required for the tannery workers to learn the use of salts to preserve animal skins during the main processing stage.
Market Insights
According to Grand View Research, Inc.; the global tannin market is projected to witness a lucrative growth over the forecast period (2014 to 2025). Growing demand from leather manufacturing and wine production is anticipated drive the global market. Laffort S.A.; Tannin Corporation; W. Ulrich GmbH; UCL Company (Pty) Ltd.; and S.A. Ajinomoto OmniChem N.V. are some of the key companies operating in the global market.
