Composting is a great way to transform your kitchen and garden waste into a valuable and nutrient-rich food for a garden or pot plants, and reduce how much you throw away. There are lots of different types of composters available and we are currently testing them out.

1000 lucky people were picked at random to receive a composter in February 2020.

Composters being trialled

Each composter comes with a kitchen caddy to make it even easier for you to compost your kitchen waste.


Space required

  • Width: 40cm, Height: Empty 56cm/Full 80cm.
  • Small and versatile. Can be placed outside preferably under cover or in a garage. Great if you do not have a garden.

Items taken

  • Yes please: Most food items and some garden waste such as: vegetables and peelings, teabags, pasta, rice, pizza, cardboard, paper.
  • No thanks: Bones, garlic, eggs, dairy, oils, spicy foods, grass cuttings.


A type of soil is created that can be used as a top dressing for pots and flowerbeds. Liquid is also passed through the bins, which makes excellent plant feed - just dilute with 10 parts water.

What happens next?

Everyone who gets a free composter will need to complete two simple questionnaires, one three months after you receive it and another six months after you receive it.

Each composter comes with an information leaflet full of advice and guidance on how to use it and get the best results.

Our compost crew vloggers will also be on hand to share the composting experience with you, so be sure to follow them on YouTube .

After 6 months, the trial will be over and the composter and caddy will be yours to keep and continue using.
