Current scientific research prioritizes sustainable and cost‐effective materials due to the depletion of traditional non‐renewable sources. Natural fiber reinforced composite materials emerge as promising solutions. However natural fibers being hydrophilic in nature are less compatible with hydrophobic epoxy matrix, to address this issue nano clay treatment of jute fibers have been done and epoxy composites were formed with their reinforcement. Through FT‐IR, thermal, mechanical, and morphological analyses, both treated and untreated composites are evaluated. The treated composites exhibit a notable 19% increase in activation energy (FWO and KAS methods) compared to untreated ones (217.5–259 KJ/mol), indicating improved thermal stability. Moreover, the treated composite demonstrates a significant 38% boost in tensile strength (30–41.4 MPa) and a 28% enhancement in flexural strength (50–64 MPa), highlighting the impact of alkali‐nano clay treatment in reinforcing structural integrity. These enhancements suggest the potential applicability of composites manufactured with alkali‐nano clay treated jute fibers (A/NC/J fiber) across various industries. This innovative approach not only bridges the gap in sustainable material development but also offers cost‐effective solutions for commercial utilization.Highlights Analyzed alkali‐nano clay treatment effects on jute fiber in epoxy composites. Studied activation energy (FWO, KAS) for untreated and treated composites. Treated composites show a 19% increase in activation energy: Thermal stability Significant improvements: 38% rise in tensile, 28% increase in flexural strength.

“…Very recently Dubey et al, analyzed the potential of pomegranate peel for bioenergy potential especially biofuel and considered only high heating rates, which results in lag of heat transfer efficiency. 24 In the current work, we have focused on pomegranate (Punica granatum L) peels as a possible alternative source of energy, a lowcost urban and industrial biomass waste. Pomegranate has been cultivated throughout the Mediterranean region since ancient times, reaching a significant world production level of about 1 million tons.…”

Pyrolysis is one of the most common, sustainable, and excellent environmental‐friendly method to evaluate the bio‐energy potential of different types of biomass wastes. Pomegranate peel is a well‐known low‐cost industrial waste. Thus, pomegranate peel's physicochemical properties were explored in detail, and a pyrolysis kinetic study and thermal behavior analysis were performed. Thermal degradation of biomass was investigated on different heating rates (5, 10, 15, and 20°C/min) by using TG‐DSC. To calculate the kinetic parameters (Ea, A), three different kinetic models were used, including the Flynn‐Wall‐Ozawa (FWO), Kissinger‐Akahira‐Sunose (KAS), and Starink methods. The average Ea values for FWO, KAS, and Starink methods are 85.2141, 80.37217, and 80.74315 kJ mol−1, respectively. Furthermore, the reaction mechanism and thermodynamic parameters (ΔH, ΔG, and ΔS) were simulated and calculated to further comprehend the pyrolysis process. The residual carbon (char) obtained after the pyrolysis process was further characterized by SEM‐EDX and BET to quantify the morphology, surface area, and porosity. SEM results revealed that the residual carbon has a honey‐comb like porous structure, whereas BET analysis reflects that PP800 possesses the highest specific surface area (SSA) ~ 1288.97 m2 g−1 with an average pore diameter of 8.85 nm. Thus, it has enormous potential to be used as adsorbent and active electrode material in energy storage devices.
