Development of Biodegradable Films from the Apple Bagasse for Controlled Release of NPK Fertilizer

In recent years, the growing concern with environmental issues has been driving the development of new technologies as biodegradable films. These materials are made from natural polymers such as polysaccharides, proteins, and lipids. They are an interesting choice to meet the growing demand for products that do not cause harm to nature. In view of the above, this work aims at developing biodegradable films from the apple bagasse, which is a waste from juice production. The films applied to the controlled release of NPK fertilizer. The degradability of the films in the soil and the efficient controlled release of nutrients necessary for the development of plants are highlighted as the main results of this work. *Correspondence: Zeni M, Research Laboratory in Materials Chemistry University of Caxias do Sul 1130, Francisco Getúlio Vargas Street, 95070560 Caxias do Sul, Brazil.
