To make biodiesel, combine a vegetable oil (e.g., peanut oil) with methanol and a base catalyst like NaOH. Heat the mixture to around 55–60°C, maintain stirring for 60–90 minutes, then let it settle. Biodiesel forms on top, glycerin settles below. After separation, the biodiesel is washed and dried. The GlobeCore USB system automates this workflow, ensuring consistent results, high conversion efficiency, and fuel purity, ideal for both beginners and professionals.
