La cadena de producción de açaí (Euterpe oleracea Mart.) es vital para la Amazonia brasileña; sin embargo, la alta generación de residuos plantea un impor- tante desafío ambiental y social. El presente artículo informa sobre prácticas experi- mentales para el desarrollo de compuestos poliméricos, con una matriz de poli(ácido láctico) y refuerzo de fibra de açaí, procesados por extrusión y prensado térmico. La variación de color entre las muestras se evaluó utilizando el sistema CIELab. Esta investigación demuestra cómo el diseño, en diálogo con la ingeniería de materiales, puede proponer soluciones innovadoras a problemas complejos, creando valor más allá de la mera función. El estudio destaca el papel del diseño en la formulación de soluciones dentro de un contexto local desafiante y su potencial de impacto ambiental y social, proporcionando una nueva dirección para la cadena de producción de açaí. Los resultados muestran muestras con variaciones de color y textura, lo que confirma la viabilidad técnica de la solución y refuerza el valor académico de la investigación como contribución al conocimiento disciplinario.
