Leather tanned with different agents was pyrolyzed in the presence of CoCl2 and MnCl2 catalysts. A bovine leather sample two inorganic tanning (chromium titanium salts) organic (glutaraldehyde methylacrylic resin) has been used this study. The samples were soaked solutions or known concentration. influence on decomposition temperature resultant pyrolysis compounds evaluated by using thermogravi...

The leather industry is currently between two opposing paths: on the one hand, recent legislative trends in terms of eco-sustainability industrial processes are leading manufacturing towards development cleaner production methods; other spread new alternative materials to driving improve its competitiveness by developing innovative and high-quality products. Leather finishing most important pha...

Tannins extracted from lignocellulosic industrial wastes, eucalyptus bark and chestnut shell, under different conditions (type and concentration of alkaline chemicals in aqueous solution and temperature), were analysed in order to establish their properties for different potential applications including: their use as phenol substitutes in the formulation of adhesives for wood derivatives and as...

A protease isolated from Pseudomonas aeruginosa PD100 could act in the presence of SDS and Tween 80. This protease could be useful for degradation of protein in the presence of solvent, dehairing of cow skin and degradation of natural proteins. The immobilized protease showed 15-20% increases in temperature stability and the entrapped enzyme retained 83% of its initial activity after six cycles...
