Abstract: Method for the extraction and hydrolysis of any protein substance, natural auxins and polyphenols from sources of plant origin and their derivatives, which from a any vegetable matter (roots, stems including bark, leaves, fruits, seeds and derivatives) and by an hydrolysis in acid alcohol which is added alcohols and mineral acids, the resulting mass is subjected to a thermodynamic treatment, with subsequent utilization of physical systems of separate solid/liquid plant extract is obtained a hydro alcoholic.

Abstract: The invention relates to improvements to patent of invention P200001758, “Method for the transformation of chrome-free tanning waste and products thus obtained”, essentially consisting in dividing the continuous process described in said patent into two sequences or subprocesses. According to the invention, during the first sequence, the industrial waste used in the process can be optimized and the range of products to be obtained can be broadened, for example, fat, calcium salt and liquid solution of peptides. During the second sequence, the liquid peptide solution is transformed into a solution of free amino acids. The process can be extended to any liquid peptide solution regardless of the nature of the liquid, since said peptides originate from a source of animal protein or from a source of vegetable protein.

Abstract: Process for transforming the residues left after tanning without chroming and the products thereby obtained, based on the process of homogenizing (2) the raw material (1), which consists of the leftovers of the tanning industry, such as remnants of skin with hair, trimmings, suede, etc. A mineral acid (3) is added to the mixture, as are semi-metals and metals (4) with a valency of 0, phenol and phenolate (15). The mixture is put in a pressure vessel (5) and is filtered (6) to separate the liquid portion (7) and the solid part (9), which can be neutralized (10) or treated with micro organisms (13). This process is intended to be used in the leather and fur industry as well as in agriculture.
