Development of Biodegradable Films from Cocoa Husk and Potato Starch for the Circular Economy in the Peruvian Rainforest

Abstract

The project addresses the environmental problem of the accumulation of unmarketed cocoa husks in the Peruvian jungle at the Wayu company. To alleviate the problem, biodegradable films were developed from cellulose extracted from foreign cocoa husks and corn starch with the aim of promoting the circular economy. The films, made with different amounts of cellulose and glycerin, were subjected to density, humidity and performance tests. The results showed that higher cellulose content increases the density and humidity of the film, while glycerin improves flexibility and water absorption. This approach demonstrates the potential of sustainable materials from cocoa husk waste.
