Desde o século XX, os polímeros ganharam destaque devido ao baixo custo e à versatilidade em embalagens e produtos técnicos variados. No entanto, sua durabilidade provoca sérios problemas ambientais, como a poluição por microplásticos. Para reduzir esses danos, surgiram polímeros biodegradáveis que se decompõem por ação de microrganismos, fungos e bactérias. Este projeto visa instalar e validar um método para analisar a biodegradação, medindo a decomposição de biopolímeros em solo simulado. O estudo avalia a biodegradação de amostras de amido termoplástico (TPS) e compósito com 5% de partículas naturais de bambu (TPS+5%PB), comparando perda de massa e análise de imagem. A técnica se mostrou eficaz para monitorar a biodegradação, sendo implementada na instituição e usada em outros estudos acadêmicos relevantes.
