The video explains the treatment of sewage and food waste using anaerobic digestion. It details how 75 million cubic meters of sewage and 35,000 tons of food waste are processed annually. The anaerobic digestion process involves cooking the waste at 35 degrees for 12 days, allowing bacteria to produce biogas. A new technology refines this biogas to a quality similar to natural gas used in homes.
