Polímeros Biodegradáveis: Aplicação na Agricultura e sua Utilização como Alternativa para a Proteção Ambiental

Abstract: O crescente consumo de materiais, desde a era industrial, vem gerando resíduos que cada vez mais prejudicam o meio ambiente. O desenvolvimento de materiais sustentáveis, que agridam menos a natureza, tende a ser uma ótima alternativa tanto para a proteção ambiental, quanto para o desenvolvimento industrial. Deste modo, surgiram os biopolímeros. Estes novos materiais são obtidos através do processo de polimerização, que consiste no agrupamento de unidades monoméricas de fontes renováveis de carbono. O surgiment… Show more

“…The two main application methods are: 1) direct application of polymer granules to the substrate, followed by addition of water (LIMA et al, 2011); 2) application of the already hydrated gel in the growing sites, or to the root system by immersion (DRANSKI et al, 2013).…”

“…According to Lima and Souza (2011), the hydrogels most used in Brazilian agriculture are synthetic, composed mainly of monomers derived from acrylic acid (and so called acrylamides), which together form the polymer polyacrylamide. However, hydrogels based on clay minerals, such as montimorilonite, vermiculite and kaolin, in addition to their natural source origins, have also aroused interest because they have advantages in terms of low cost and lowering of environmental contamination risks (BRITO et al, 2013, SABADINI, 2015.…”

“…In the late twentieth century, the damage caused by polymers in the environment became a concern worldwide. As an alternative to this scenario, biopolymers or biodegradable polymers emerged, which are plastic materials with similar properties to those of conventional polymers, but with a shorter degradation time (de Lima and de Souza, 2011).…”
