Waste biomass derived catalysts have been receiving considerable interest recently as a heterogeneous catalyst for the synthesis of biodiesel since it can be recycled in production processes and doesn't cause soap to form. This study looked at the catalytic activity of waste kiwifruit ash as a catalyst to make biodiesel from waste soybean cooking oil transesterification. It was found that the ash from dried and burned waste kiwifruit may serve as a heterogeneous catalyst for the synthesis of biodiesel that was both economically and environmentally friendly. By using TGA, WD-XRF, and XRD, the synthesised catalyst was analysed. Using reaction conditions at 65 °C for 60 minutes, a 2 wt% catalyst dosage, and a 10:1 methanol to oil molar ratio, waste soybean cooking oil was transformed to biodiesel with a yield of 91%. The reaction product is confirmed by utilising the GC method. Studies on recycling concluded that the produced catalyst retained a high activity up-to three cycles.
