    (2023) Shirley Vega; Garvizu Auza; Vidfa Carolina; Alvizuri-Tintaya; Paola Andrea
    Coffee is one of the most popular drinks worldwide. Although the coffee industry is of great economic importance, it is considered an activity that produces a significant environmental impact. According to studies carried out, organic coffee wastes become a pollutant agent due to the presence of caffeine, polyphenols, and tannins, among the most important. This research proposes a methodology for the elaboration of a biomaterial from the mixture of coffee grounds with natural polymers. The study of the physical characteristics of the material and its biodegradability were developed to analyze its applicability. Results reveal a potential for the use of coffee grounds, being a possible solution to its generation in Bolivia, the fifth most important country in terms of coffee production in South America.
