In most households, kitchen waste is often discarded, but recently a viral video from China totally changed the way the world threw away food waste for years! As per the viral video, Chinese school canteens handle leftover food in a unique way, and it is gaining massive traction on social media platform X. So, instead of tossing scraps into the trash, students dump their plates directly into a specialized machine designed to squeeze every bit of value out of what’s left behind. The clip, shared by X user Massimo, reveals a simple yet clever process that turns daily cafeteria scraps into biodiesel and nutrient-rich compost.How the machine works?As per the viral video, the process starts as soon as students finish eating. Leftover rice, meat, vegetables, and other scraps are emptied straight into the machine, which immediately crushes everything into a thick slurry. This step makes it much easier to separate the different components. Next comes one of the most critical steps: separating oil from water. The machine extracts the recovered oil so it can be collected and turned into biodiesel.Turning scraps into compostThe rest of the food that people do not eat does not go to waste. Bacteria are used to break down the food waste. This process takes time. It turns the leftover food into compost. The compost can be used to make the soil better of putting it in landfills.What is biodiesel? Why does it matter?Biodiesel is a type of fuel that comes from natural things like oils and fats. It is not made from oil. In school cafeterias, old food oil is used to make fuel. Of throwing away grease it is turned into something useful.Building a systemOne of the good things about biodiesel is that it gives old things a new life. Using oils means we do not need to use new resources as much. It also means less food ends up in landfills. When we use oil for energy and turn the rest into compost for the soil, almost all of the food gets used again in a circle.Why the video is going viralThe video is popular because it is easy to use. Students just need to clean their plates after lunch. The machine does the rest of the work. It separates the oil. Gets the leftover food ready to be turned into compost. This all happens automatically. The food waste becomes compost. The oil becomes biodiesel. This way the food waste is used to make the soil better. The oil is used for energy. The biodiesel and compost are useful things that come from food waste.
