“…The bands comprised in the range 1600–1700 cm −1 and 1550–1570 cm −1 were related with amide I (C=O stretching of proteins) and amide II bands (C–N stretching and N–H bending of proteins) also to collagen respectively [ 34 ]. As previously described in the literature, similar results were reported for BF waste by Ambone et al (1625–1535 cm −1 ), Cardona et al (1650–1540 cm −1 ), Senthil et al (1643–1540 cm −1 ), and for chromium shaving waste by Mohamed et al (1650–1540 cm −1 ), Li et al (1645–1544 cm −1 ), and Liu et al (1647–1545 cm −1 ) [ 11 , 12 , 35 , 36 , 37 , 38 ].…”

“…BF fibers showed the bands related with the aminoacids groups of collagen. The peak at 3295 cm −1 is assigned to the characteristic of –OH and –NH stretching vibration of amino acid in leather waste, and in the literature on this band reported between 3000 and 3500 cm −1 [ 11 , 12 , 34 , 35 , 36 , 37 ]. The bands comprised in the range 1600–1700 cm −1 and 1550–1570 cm −1 were related with amide I (C=O stretching of proteins) and amide II bands (C–N stretching and N–H bending of proteins) also to collagen respectively [ 34 ].…”

“…Los residuos agroindustriales pueden generar cambios significativos en el proceso de vulcanización de los compuestos de caucho natural. La naturaleza ácida o básica de los residuos genera cambios en los tiempos empleados para la vulcanización del caucho, por ejemplo el tiempo que se demora para comenzar la reacción de vulcanización o tiempo "scorch" (t scorch ) puede ser alterado por la incorporación de los residuos, al mismo tiempo que puede ser alterado el tiempo óptimo de vulcanización (t 100 ); el tiempo necesario para alcanzar el 90% (t 90 ) de la vulcanización es un parámetro empleado en el sector cauchero, por lo que es común en algunos trabajos encontrar reportado el t 90 en lugar del t 100 (Urrego Yepes et al, 2018;Ravichandran and Natchimuthu, 2005a;b;Cardona, Velásquez and Giraldo, 2017). Los torques máximo (M H ) y mínimo (M L ) obtenidos mediante la reometría de vulcanización también pueden verse afectados por la incorporación de los residuos posindustriales, esto se debe al aumento en la viscosidad del caucho natural al incorporar los residuos, efecto que se verá reflejado en el aumento del torque mínimo (M L ) o un aumento en el torque máximo (M H ) como resultado del efecto reforzante de los residuos, representando un primer acercamiento a las propiedades mecánicas de los compuestos.…”
