Food waste has significant social impacts affecting human lives. It not only causes hundreds of billions of dollars in global economic losses annually, but also damages the environment and contributes to the climate crisis. When food waste is disposed of in landfills, it decomposes and produces large amounts of methane gas, which contributes to the greenhouse effect.
