Anaerobic Digestion is a natural biological process where organic material, in our case food waste, is broken down by bacteria. It is similar to composting but differs in that it takes place in sealed, oxygen-free tanks to produce biogas that can be used to generate electricity and heat. Currently, much of our biodegradable waste is sent to landfill, where it breaks down to release methane, a powerful greenhouse gas. AD helps tackle climate change by diverting this waste from landfill and incineration.
