Energy from residual waste is a partially renewable energy source, sometimes referred to as a low carbon energy source. The energy it generates is significantly cleaner and less carbon producing than traditional sources and provides a responsible solution to the ever-growing problem of how UK business and wider society manages its waste. Landfill is the worst option for disposing of non-recyclable waste at scale. The energy produced by facilities such as Northacre is simply a useful by-product of this process.
