SMART BIOCONVERSION OF PELT WASTE FROM TANNERIES
Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2017, Vol 0, Issue 2
Abstract
The area of interest is the synthesis and study of properties of new types of hydrogels made from pelt waste, in order to recover waste from tanneries. Leather processing in tanneries results in about 500-600 kg of pelt waste from a ton of raw hides. These hydrogels are made using smart processes in order to then be applied in agriculture, for preservation of water in the soil or for controlled release of fertilizers, pesticides but also for the development of additivated agricultural film biodegradable over time (between 1 month and 6 months). Hydrogels that are based on biopolymers, compared with hydrogels based on synthetic polymers, have the advantage of biodegradability, biocompatibility, and a low level of toxicity. The paper presents the production of biodegradable polymer mixtures obtained from hydrolysis and enrichment of the resulting hydrolysate with phosphorus and potassium. Hydrogels with collagenous structure are tested using a high-performance instrumental analysis system (FT-IR-ATR, UV-VIS-NIR, SEM, EDAX, etc). The paper presents an experimental model for obtaining hydrogels with collagenous structure from pelt waste resulting from the liming process.
