The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…POE's aging resistance is better, cohesion is smaller, light transmittance is better, and adhesion is more long-lasting, so it is more adaptable to the common use of photovoltaic cells. Silane coupling agents have been studied to promote the adhesion of polyolefins within a certain dosage range [15][16] . This article will further explore the effect of silane coupling agents on the material enhancement of EVA.…”

Grafts of silane coupling agent EVA and POE were prepared by twin-screw melt extrusion method to obtain grafts EVA-g-KH171 and POE-g-KH171. The effect of silane coupling agent KH171 on the properties of two commonly used encapsulants in the photovoltaic field was investigated. The changes in the melt index of the grafts were tested by different dosages of silane coupling agents to explore further the effect of the changes in the melt index of the two grafting products, namely, EVA and POE, on the peeling strength. With the addition of the silane coupling agent, the melt index of the grafting product of EVA and POE increased. The peel strength test showed that the silane coupling agent KH171 had a more significant improvement in the adhesion of EVA and POE, proving the feasibility of its application in practical conditions.

Natural fibre matrix composites have been utilized in numerous industries, including the automotive, construction, and aerospace sectors. Maleic anhydride grafted polypropylene (MAPP) was used in this study to examine the effect of the coupling agent on the properties of a composite-produced using pineapple leaf fibre. The weight ratios of pineapple leaf fibre, polypropylene, and MAPP were 20g:180g, 15g:180g:5g, and 10g:180g:10g, respectively. The materials were mixed using a co-rotating twin-screw extruder machine at 170 °C and 50 rpm. The composite was then manufactured by injection molding at 185 °C. The mechanical and physical properties of PALF composite were examined by using a tensile test, impact test, and water absorption test. Thermal Gravimetric Analysis (TGA) was used to characterize the thermal properties of PALF/PP, and PALF/PP/MAPP composite. The surface morphology and fracture surface of the composite was characterized by using Scanning Electron Microscopy (SEM). Compared to the composite containing 5 g of MAPP, the tensile strength composite containing 10 g of MAPP produced a stronger interfacial bond. According to the impact test, adding more MAPP increases the material's strength and stress transmission. The average percentage of water absorption indicates low water absorption after the addition of the coupling agent. It can be concluded that the addition of a coupling agent improved the composite's properties.
