Ditch the foil and the cling film when wrapping your sarnies, a waxed cotton wrap is going to be better for the environment.
Asked by: Mark Chapman
We tend to assume that plastic is always the worst option for the environment. But when it comes to wrapping your sandwiches, aluminium foil – even though it’s recyclable – is worse than cling film.
Aluminium mining is energy-intensive and polluting: per square metre, aluminium foil contributes three times as much water pollution and six times as many greenhouse gas emissions. So unless you reuse the same foil six times, cling film is better. For an even better option, try a waxed cotton wrap, which can be reused for months.
