Food makes up almost half of the rubbish in our rubbish bins.

Reduce the amount of food waste by composting food scraps in a compost bin or worm farm.

Composting has many benefits:

  • saves space in your bins.
  • it can be used as fertiliser on your garden.
  • it can improve the condition of your soil.

How to compost

There are different ways to compost your food waste:

Compost bins

Are large enclosed bins, in which you can place a mix of food scraps and garden clippings. Compost bins are useful if you have a garden in which to use the compost, and a source of dry material such as autumn leaves, old mulch or brown clippings required for the composting process.

Worm Farms

Are enclosures which house bedding and composting worms. Food scraps can be added to the worm farm at regular intervals to be eaten by the worms. The worm farm then produces a compost-like material called ‘castings’ which can be used as a fertiliser, as well as a liquid fertiliser that drains from the worm farm into the bottom tray. Worm farms are great if you have a small garden, or children who would like to keep worms as pets.

Bio-fermenter bins

Use beneficial microbes to ferment food waste. These bins are compact, air tight and odour free, and are great if you don’t have a garden as they are designed to sit in your kitchen. The material placed inside the bin is fermented and decreased in volume over weeks. The end material does need to buried in a small garden bed for disposal.
