Madam, – Although James Nix (December 19th) says that incinerating waste produces carbon emissions (which is quite correct), he fails to mention that incinerating the waste reduces the amount of waste sitting in landfill sites and produces electricity for us to power our homes. He also fails to mention how recycling produces emissions without producing power. So does he suggest we keep filling the fields with waste and keep burning fossil fuels for our power? – Yours, etc,
