| titleOfInvention | PROCESS FOR OBTAINING PROTECTIVE BIOPOLYMERS OF TITAN |
| abstract | The invention relates to a process for producing a protein biopolymer from wet-white leather wastes used as fertilizer in agriculture. According to the invention, the process consists in mixing, in a first stage, 1000 g of leather waste, comprising titanium, with 5...10 l of water whereto there are added 7...10 % CaO or 2...5% MgO and 2...5% NaOH for 4...6 h, then the mixture is hydrolized in an autoclave, there adding 3...7% potassium hydroxide and 0.3...1% boric acid at 90...98°C for 2.5 ...5 h, then the hydrolysate is passed through a 0.5...1 mmmesh screen, there resulting a liquid part and a sludge part comprising 4...9 % titanium, after which, in the second stage, 500 g of leather waste are mixed with 300...500 g of titanium-containing sludge and are pre-treated with 5...10 l of water and 1.5...3 % MgO and 3...5 % NaOH, at room temperature for 4...6 h, finally there are added 2...5% edible starch and 0.5...1% enzymatic commercial product, containing lipase, cellulase, amylase and protease for 1...2 h at a temperature of 35...40°C, from which there results a protein polymer having 63...89% organic substance and 289...935 mg of nitric nitrogen/100 g of polymer and a pH of 7...7.8. |
