Stratford inventor taking his home waste solution to COP26

Also joining world leaders in Glasgow is a Stratford inventor who says he can help the UK meet its carbon emission targets.

Nik Spencer has built a machine called a HERU, which turns your rubbish into ash while using it to heat water and then produces a gas that can power a boiler.

Nik says inventions like this could stop millions of tonnes of CO2 from entering the atmosphere.
