ABSTRACT This study explores the reinforcement of recycled e‐waste ABS with halloysite nanotubes (HNT) to improve its mechanical, thermal, and fire‐retardant properties, while potentially mitigating some risks associated with its reuse. Samples of e‐waste ABS filled with 5 wt.% HNT were melt‐compounded and characterized using SEM–EDX, XRD, ATR‐FTIR, TGA, PCFC, MFR, and tensile measurements. Commercial ABS and recycled e‐waste ABS were also tested under the same conditions for comparison. The results demonstrate that HNT enhances the thermal stability of e‐waste ABS, increasing the degradation temperature (T 5 % ) by nearly 11% compared with unfilled e‐waste ABS. The peak heat release rate (pHRR), an indicator of fire intensity, slightly decreases, likely due to the physical barrier effect of the nanotubes. Mechanical properties are also improved, with Young's modulus increasing by 12% over commercial ABS while maintaining comparable tensile strength. SEM analysis confirms a good interfacial adhesion between HNT and e‐waste ABS matrix, supported by ATR‐FTIR and XRD data. The study highlights the potential of HNT as a reinforcing additive to upgrade recycled e‐waste ABS, improving its performance and expanding its applications while addressing some of the challenges posed by its inherent toxicity. Further research is needed to assess the long‐term environmental impacts of modified e‐waste ABS composites.
