Tannage Résumé : In line with the resurgence of natural product dominance in the global manufacturing industry, leather industry is also re-looking at the possibility of increased use of organic materials. With a view to exploit the benefits of the vegetable tanning materials and to overcome the inherent shortcomings of vegetable tanning materials by suitable coupling with organic auxiliaries, studies were undertaken. Tanning materials based on acrylics have advantageous properties such as preferential filling of voids, good fastness properties and compatibility with other tanning materials and auxiliaries. Based on the hydrothermal stability, uptake of tannins, physical strength properties and assessment of crust leathers, one commercial acrylic retanning material was chosen for the combination tannage with vegetable. The acrylic treatment followed by vegetable tanning produced better results in terms of hydrothermal stability and uptake of the tannins. The concentration of the acrylic was also optimised. The study indicated that pretreatment of pelts with acrylic in 1:10 ratio with vegetable tanning material enhances the hydrothermal stability by 10±2o C compared to conventional vegetable tanning system and produced finished leathers comparable to that of conventional tanning systems.

Tannage Résumé : In the present study, we studied the feasibility of using Salicornia brachiata as a phytoremediant for accumulation of NaCl present in tannery wastewater. The plants were grown in pots fed with tannery wastewater with varying concentrations of NaCl. The accumulation of Na+ and Cl- increased with increase in salt concentration of tannery wastewater offered to the plant. The growth of the plants with respect to root and shoot length decreased with an increase in salt concentration. However, the accumulation of Na+ and Cl- increased with time of growth and plant density. 51 % of Na+ and 33 % of Cl- were absorbed by the plant at an NaCl concentration of 20 000 ppm at high plant density conditions. Based on the results of trials, Salicornia brachiata was grown on open lands in Tamil Nadu State, India where tannery wastewater was discharged. The TDS levels of the land decreased from 10 300 ppm to 5500 ppm at the end of one year by the growth of S. brachiata. The maximum accumulation of Na+ and Cl- was observed during the period July to September. The results of the present work indicate that S. brachiata ca be used to accumulation of sodium chloride from tannery wastewater discharged lands, thereby contributing towards solving TDS problem arising from the leather sector.
