Resumen
La economía circular, una estrategia clave para contrarrestar el agotamiento ecológico. En ella destaca la reutilización de polímeros y la generación de nuevos biocomposites para reducir el impacto ambiental. La provincia de Jaén, con una gran superficie de cultivo del olivar, genera numerosos residuos, como poda y hueso de aceituna. Esta Tesis Doctoral aborda la fabricación de biocomposites reforzados con estos residuos. Para ello, se emplearon fibras de madera y celulosa de la poda del olivo, así como nanocristales de celulosa, para reforzar una matriz de ácido poliláctico (PLA) presentando mejoras en propiedades mecánicas. El hueso de aceituna se evaluó en dos matrices poliméricas polipropileno reciclado (rPP) y PLA, evaluando el efecto de su incorporación conjuntamente con dos aditivos en el rPP y su impacto en la degradación ambiental del PLA. Este estudio trata de transferir resultados
directamente a la industria, promoviendo soluciones sostenibles y reduciendo el impacto ambiental.
The circular economy it is a key strategy to reduce ecological depletion. It includes the reuse of polymers and the generation of new biocomposites to reduce environmental impact. The region of Jaén, with a large olive-growing area, generates a huge quantity of waste, such as pruning and olive pits. This PhD is concerned about the manufacture of biocomposites reinforced with these wastes. For this purpose, wood and cellulose fibres from olive pruning, as well as cellulose nanocrystals, were used to reinforce a polylactic acid (PLA) matrix improving mechanical properties. Olive pit was evaluated in two polymeric matrices, recycled polypropylene (rPP) and PLA, assessing the effect of its incorporation with two additives in rPP and its impact on the environmental degradation of PLA. This study aims to transfer the results directly to the industry, promoting sustainable solutions and reducing the environmental impact.
