The gradual increase in the consumption of fossil fuels, coupled with the current economic and social situation, has created the need to seek alternatives for the self-sufficiency of territories, thereby promoting an increase in socio-economic well-being in the surrounding areas. Second-generation bioethanol derived from lignocellulosic waste from the agro-industrial sector is a biofuel with high potential, which can take advantage of existing infrastructure. In this line, several full scale experiments were performed in real environment in a distillery factory in the island of Gran Canaria. After performing acid hydrolysis and enzymatic hydrolysis using sugarcane bagasse from the factory, it has been observed that good yields cannot be achieved without the pretreatment stage, with acid hydrolysis (<30%) and enzymatic hydrolysis (<79%) performing poorly. In comparison, alkaline pretreatment in enzymatic hydrolysis has shown superior conversion rates exceeding 80%. However, an optimal time has been sought for our working conditions to limit the formation of inhibitors, which would have a negative impact during the subsequent fermentation process.

Even some natural resources, considered as waste, can be used for manufacturing a lot of products with enhanced sustainable properties, such as cellulosic bagasse. In this review was performed in order to gather state of the art about natural fibers structure, properties, and applications in polymer composites reinforcement, giving an approach of bagasse sugarcane fibers. The literature was done in different scientific databases;more than 50 papers wereanalyzed. The vegetable fibersare an extensive and multipurpose group, bagasse sugarcane fibers emerge as a remarkable renewable resource, due to their suitable properties and a large amount of available resources worldwide. Nevertheless, this kind of products require the use of adequacy physical and chemical treatments in order to achieve an adequate proper interaction with polymer matrices, additionally, other characteristics as the geometry and fiber content can influence the performance as reinforcements in composite materials.

La importación de vinagre y sucedáneos del vinagre en Ecuador es constante. El vinagre es un líquido miscible, con sabor agrio, proveniente de la fermentación acética del vino a partir, inicialmente, de azúcares fermentables. El objetivo del presente proyecto consistió en evaluar el rendimiento de vinagre obtenido de la pulpa de banano (musa paradisiaca) mediante la fermentación bifásica alcohólica y acética; así como también estimar la producción a una escala industrial junto con el diseño de los reactores para el proceso. Los resultados obtenidos mostraron que inicialmente la producción de etanol se mantiene estable durante la mayor parte del proceso, lo cual brinda un rendimiento del 75 %. Posteriormente en la fermentación acética se obtiene un rendimiento del 16,1 %. Finalmente se concluye que para el caso de la fermentación acética es preciso el control de cultivo y crecimiento con el respectivo ajuste de variables para obtener así mayores rendimientos, también es necesaria la implementación de biorreactores en serie como criterio que garantice el mejor desempeño del proceso productivo. Palabras clave: banano, fermentación bifásica, vinagre, biorreactores.
