The Marchwood Silver Dome is a state-of-the-art energy recovery facility in Southampton, England that opened in 2007. It processes 165,000 tonnes of household waste per year, generating enough energy to power over 22,000 homes. Any non-recyclable waste is burned to produce steam that powers generators, while recyclables are separated out. The facility helps reduce landfill and dependence on fossil fuels by recovering energy from waste.
