“…Nevertheless, the incorporation of 40 phr of GTR provided a higher hardness value than others. 22 This is because of higher stiffness and good uniform dispersion of filler after vulcanization, which results in higher hardness. 23 The hardness was increased by 36.4% when compared with the NR/BR/SBR composites.…”

In this work, investigated the mechanical properties and microstructure of Ground Tyre Rubber (GTR) i.e. polymeric waste blended with Natural Rubber (NR), Butadiene Rubber (BR), and Styrene-Butadiene Rubber (SBR) composites. A two-roll mill and hydraulic press were used to create NR (70 parts per hundred of rubber (phr)) composites with 25 phr of BR and 5 phr of SBR and various proportions of GTR (0, 10, 20, 30, and 40 phr). With the incorporation of Nylon 6 (Ny 6) at 5 phr, the interfacial adhesion of NR/BR/SBR composites was improved. NR-based hybrid composites with mechanical and curing properties were enhanced and compared with pure NR. It was noted that the maximum tensile strength, tear strength, and hardness were enhanced by 77.74%, 17.9%, and 36.4% in NR/BR/SBR/GTR (70/25/5/40) over pure NR. The elongation at break was decreased by 54.55%, while young’s modulus was enhanced in NR/BR/SBR/GTR (70/25/5/40) over pure NR. With the incorporation of 40 phr of GTR in the NR/BR/SBR composites, cure properties like scorch time (tS2) and cure time (tC90) were reduced by 53.97% and 65.71%, while the minimum torque (ML) and maximum torque (MH) were enriched by 13.35% and 12%, respectively, when compared with the pure NR. Based on the Scanning Electron Microscope (SEM) and Thermogravimetric Analysis (TGA), GTR particles were uniformly distributed, and the thermal stability was enhanced by 25.40% in NR/BR/SBR/GTR (70/25/5/40) composites over pure NR. The absorption bands of NR, BR, SBR, and GTR elements in the developed hybrid composite were identified by Fourier transform infrared. The glass transition temperature (Tg) was diminished from -58.17°C to -63.42°C. With the inclusion of 40 phr of GTR in the NR/BR/SBR composite. Finally, it was recommended that the incorporation of 40 phr of GTR is suitable for NR/BR/SBR composites.

“…Bowles et al (2020) indican que dependiendo del tamaño de la goma se puede adicionar 5 % del caucho reciclado para la elaboración de una llanta nueva. Kaliyappan et al (2020) destacan que es posible desarrollar un compuesto híbrido de caucho natural-neopreno utilizando diferentes rellenos de residuos de caucho y carbón, incluyendo un efecto de variación de negro de humo sobre la morfología y las propiedades mecánicas del compuesto fabricado. Arabiourrutia et al (2020), en España, buscaron determinar cómo se puede hacer la valorización de neumáticos mediante pirólisis catalítica, demostrando que mediante esta técnica se pueden obtener subproductos de la llanta como gases, aceite y carbón.…”

En Colombia las llantas usadas no son consideradas un residuo peligroso. Sin embargo, estas se componen de sustancias con dicha connotación, las cuales generan impactos negativos sobre la salud y el ambiente si no se realiza un manejo adecuado. Aunque en Colombia se han generado instrumentos normativos de sistemas de recolección selectiva, se tiene escaso conocimiento de aspectos relacionados con su gestión, generación y manejo; situación que se acrecienta en municipios de baja complejidad donde a pesar de su generación no se realiza seguimiento y la oferta de empresas de recolección o centros de acopio es limitada. Por ello, se realizó un estudio sobre la gestión de llantas usadas en municipios de baja complejidad de la Provincia Centro del departamento de Boyacá, con el fin de indagar acerca de su generación, disposición y manejo, al igual que sobre el conocimiento de programas de recolección selectiva, aprovechamiento y cumplimiento de normatividad. Se aplicaron encuestas a establecimientos de 14 municipios de la provincia cuyas actividades comerciales estuvieran relacionadas con la distribución, el almacenamiento o el montaje de llantas. Se identificó desconocimiento del tema por parte de los administradores de los establecimientos evaluados y falta de acercamiento por parte de los proveedores de estos municipios. Aunque existen estrategias que permiten realizar un manejo adecuado de las llantas usadas, se hace necesaria la inclusión de los diferentes actores involucrados, así como el aumento de incentivos o beneficios para empresas que realicen este proceso de manera apropiada, o para quienes realicen actividades de reutilización, lo cual favorecería la gestión adecuada de este residuo.

“…The reinforcement of CB‐loaded crosslinked rubber is primarily attributed to the nanoscale particle size, high surface area, and high specific surface activity that foster robust interactions between the rubber and CB 51 . CB can be applied to many polymers such as polyvinyl chloride, 52 polycarbonate, 53 polyvinyl alcohol, 54 neoprene rubber, 55 and natural rubber (NR) 56 . In addition, the annual global output of CB is reportedly 15 million metric tons, and vehicle tires account for 73% of that production, while the remaining 20% is used in other rubber products 48 .…”

Fly ash (FA), a by‐product of the power generation industry, can potentially be used as a filler in polymer products. Particularly, FA has been investigated as an alternative filler to partially or fully replace commercial fillers in polymer composites. This mini‐review discusses the fundamental properties of FA, environmental pollution from commercial fillers, and the performance of FA in polymers. The properties of FA‐loaded polymer composites are discussed, including the morphological, rheological, mechanical, and thermal properties. This review highlights the potential methods and challenges for substituting, or replacing, commercial fillers in various polymers such as natural rubber (NR), epoxidized NR, epoxy, styrene‐butadiene rubber (SBR), NR/SBR blends, polyethylene, polypropylene, and polyester.
