mechanical and microstructural properties of bio-composite produced from recycled polystyrene/chicken feather biochar

Polystyrene waste is a significant environmental problem, and recycling and repurposing it can reduce its impact on the environment. chicken feather biochar, on the other hand, is a by-product of the poultry industry and can be repurposed to produce bio-composites. the goal of this work was to turn waste chicken feathers into biochar and then, create composites with the biochar acting as the filler and a polystyrene-based resin acting as the matrix. the biochar was prepared with the aid of a top-lit updraft reactor. composites were fabricated using different mixing ratios of biochar (10-40%) and polystyrene resin. the composites were then analyzed using ftir, sem-edx, and hardness tests. sem examination demonstrated that the biochar was distributed unevenly throughout the matrix. the alterations and shifts in peak positions shown by ftir measurement indicated that there was a chemical interaction between the matrix and the biochar. it also revealed the hydrophilic nature of the composite. hardness test showed that 20% biochar concentration gave the optimum hardness property (139 hrb). the edx result demonstrated that the matrix as well as the composites consisted majorly of carbon atoms. the results of this study indicate the potential of using chicken feather biochar as a filler material to improve the mechanical and microstructural properties of recycled polystyrene-based bio-composites. this approach can provide a sustainable and environmentally-friendly solution to repurpose waste materials from poultry and plastic industries.
