Your food waste could be transformed into electricity to power homes, or be turned into compost for farmers to fertilise crops!

food waste into energy and compost
Food waste that is thrown away doesn't break down harmlessly like you might think. If food waste ends up in landfill, it rots and releases methane, a greenhouse gas which is 25 times more potent than carbon dioxide - very bad news for the environment.

When we recycle our food waste, we can avoid needlessly pumping tonnes of methane and carbon dioxide into the atmosphere, and create something useful instead. Food waste is never actually waste, as it can be sent to special processing plants to be transformed into electricity, or turned into compost for farmers to use as fertiliser. To find out more about how these processes work, watch our animations on Anaerobic digestion and In-vessel composting.

The following facts might surprise you

  • For every SIX tea bags we recycle, enough energy can be produced to make another cup of tea

  • Just ONE caddy load of food waste generates enough electricity to watch a footie match on TV

The best thing to do with our food is enjoy it, but some waste is inevitable. Think:

  • Tea bags and coffee grounds

  • Fruit and veg peelings and cores
  • Fish and meat bones
  • Mouldy or gone off food, including dairy, but no milk please!
  • Egg shells
  • Plate scrapings

To help you, here are some top tips for recycling food waste.

This February and March, we're running a special food waste campaign in five boroughs, supported by Sainsbury's. Keep an eye on our events page to see if we're coming to your area.
