A plant in South Italy is using a special process to turn food waste into useful products. They use anaerobic digestion and composting to create biogas for transportation and high-quality compost for farming. They also make fuel for waste-to-energy plants and turn odour emissions into fertilizer. The plant is powered by solar energy and has a very low carbon footprint. In 2020, the plant's activities resulted in a negative carbon footprint, meaning they actually removed more CO2 from the atmosphere than they produced. The plant's use of biomethane instead of natural gas made the biggest positive impact on the environment.
