“…25 This weak adhesion contributed to the inefficient stress transfer leading to a decrease of the strength. 26 However, the addition of 30 wt% of RWS in the composites with the GRT/PP blend of a 30/70 ratio improved the MOR of the composites. This was probably because the optimal RWS content in the GRT/PP blend of the 30/70 ratio was about 30 wt% for the MOR.…”

Waste tire disposal is a growing challenge among major cities worldwide because each year, a huge number of end-of-life tires is generated. The current study aimed to evaluate the potential of ground rubber tire (GRT) and waste rubberwood sawdust (RWS) as materials for developing wood-polymer composites (WPCs). The effects of the compositions’ contents and rubber types on the mechanical and physical properties, as well as the morphology of the thermoplastic elastomer (TPE)/RWS composites were investigated. The results revealed that the addition of about 30–60 wt% of RWS improved the modulus of elasticity, compressive modulus, and hardness of the TPE composites based on both the GRT and natural rubber (NR). With the same RWS content and rubber type, the TPE/RWS composites with rubber/plastic blends of a 30/70 ratio clearly yielded better mechanical and physical properties than those blends with a 40/60 ratio. The addition of about 2–4 wt% of maleic anhydride-grafted polypropylene (MAPP) improved all the properties of the TPE/RWS composites. Overall, the composites based on the GRT gave superior strength, rigidity, and dimensional stability than that based on NR. It is therefore suggested that the eco-friendly TPE composites made from GRT and waste rubberwood could be a suitable replacement for the inorganic filler-natural rubber composites for saving costs and the environment.

“…Greater waste disposal means more environmental issues and dangerous threats. This happens especially in metropolitan regions where rubbish wastes such as containers, food packaging materials, plastic shopping bags, bottles, and other nonbiodegradable objects pollute the environment [4]. Using waste resources in unique products is one of the most cost-effective and appropriate solutions to such a problem.…”

Concrete is the most commonly used and dependable substance and the most consumed among all other construction materials. However, the construction industry’s insatiable need for building supplies has led to the widespread exploitation of natural resources like river sand and stone. However, one of the most pressing problems in the construction industry and others nowadays is excessive waste and byproducts. Promoting ecological control and the goal of sustainable progress has put environmental pressure on all businesses, including construction, to embrace eco-friendly practices. Environmentalists’ concerns about the dangers posed by the widespread use of natural resources in building construction are growing. In some instances, construction debris may be harmful to the environment. Global building growth and redevelopment plans have worsened demolition in the construction industry. The demand for construction materials is increasing yearly due to urbanism, but their costs are rising simultaneously. Using industrial waste like polymers and rubbers and natural waste like olive stones and pumice stones to replace cement, fine aggregate, and coarse aggregate to reduce building costs conserves natural resources from exhaustion and protects the environment from waste impact and risks. The current research shows how waste can be used to replace materials on construction sites and the impact of the properties of these materials on the quality of concrete.

Natural fiber-reinforced composites can contribute to reducing carbon footprint goals due to their ability to reduce overall product weight, bio-diverse feedstocks, and recyclability potential. In this work, natural fiber-based composites containing the reinforcement of coconut husk and bagasse fiber with calcium carbonate (CaCO3) ingredients were prepared and analyzed. The composites were analyzed for mechanical, thermomechanical, and morphological properties. The reinforcements were chemically functionalized using 5% w/v NaOH to enhance their interactions with the epoxy resins. The chemical functionalization created perforation on the fiber surface, improving the interlocking of fibres with the resin material and strengthening the mechanical performance of the composite. The composites developed using modified reinforcement treatment resulted in increased tensile strength (64.8%) and flexural strength (70%). The reinforcement treatment influenced the hydrophilicity, and the water absorption of treated composites was reduced more than five times compared to the unmodified composites. Scanning electron microscopy revealed morphological changes due to fiber modification, the underlaying mechanism of fiber contraction, and enhanced fiber matrix interface interlocking and adhesion strengthening. Thermal analysis confirmed that alkali treatment improves the crystallinity of the fiber and thereto the degradation temperature of treated fiber composites (both bagasse and coconut husk), which is 375.27 °C, the highest amongst the developed hybrid composites.
