Elaboración de láminas biodegradables y flexibles obtenidas a partir del extracto de colágeno de patas y queratina de plumas de pato pekinés (Anas platyrhynchos).

Abstract

One of the main factors influencing environmental pollution and climate change is the accumulation of single-use plastic waste obtained from nonrenewable raw materials, which usually ends up in the oceans or on the ground, taking decades to decompose. Faced with this problem, the objective of this work is to develop, from waste from the food industry, flexible and biodegradable plastic sheets that can be used as a replacement for conventional plastics, thus promoting the circular economy by giving added value to agro-industrial waste. To obtain these sheets, the waste generated after processing poultry intended for food will be used, specifically the collagen and keratin present in the legs and feathers of the Pekingese duck (Anas platyrhynchos), respectively. These proteins will be extracted by hydrolysis and the extracts obtained will be mixed with glycerin in different concentrations, in order to establish, based on mechanical and degradation properties, the best formulation for the development of biodegradable and flexible plastic sheets. A profitability proposal will be made to compare in detail what the development and marketing of the project would cost.
