The goal of the EfW plant in Severnside was to thermally treat the lion’s share of municipal and commercial waste collected in West London rather than disposing of it in landfill. Now the plant generates enough electricity for 50,000 households. If required it can also be switched over to additional heat generation. Another special feature of the project is that most of the waste is delivered for treatment by rail via a station built specially for this purpose by the waste bunker.
