Which Composting Bins?

Posted by Catherine Wainwright, on March 15, 2024.

Composting bins are invaluable tools for recycling organic waste into a nutrient-rich soil enhancer. Available in various sizes and designs, these bins provide a contained environment where food scraps, garden waste, and other biodegradable materials decompose and transform into compost. Whether you have a large garden or live in a small apartment, there’s a type of composting bin that will help you embrace sustainable gardening.

When choosing a composting bin, it is important to consider the following factors to find the right bin for your needs:

  • Amount of waste.
  • Indoor or outdoor space.
  • Composting time.
  • Time setting up the bin.
  • Costs.

DIY Compost Bins

It is possible to make your own composting bin from repurposed materials like wooden pallets or recycled containers. These bins offer a cost-effective and customisable approach to composting. Note that while they are low cost, this method may require more work compared to buying a prefabricated composting bin. Here are a couple of ideas to get started, although making your own composting bin is a great opportunity to be creative. Consider that composting bins need to be ventilated, have contact with the soil, and be placed in a sheltered location away from direct sunlight.

Rubbish Bin

Large or small rubbish bins make great composters. They can be either plastic or metal and ideally, choose one that has a lid to help protect your compost from the rain. It is important to create plenty of ventilation holes in the sides and base of your bin — an effective way to do this is by using a paddle drill. Cover the holes with a wire mesh to prevent rodents from climbing in or compost from falling out.

Wooden Pallets

Wooden pallets can be made into a simple, effective composting bin. Construct this bin to the size you need and build it directly in the intended location in the garden. This style of bin allows for regular turning of your compost. Stand a pallet on its side and secure it on the ground using stakes. Secure the next 2 pallets at right angles to the first, creating an open square — wire the pallets at the corners to secure them together. The final pallet can be attached with wire to just one corner, to create a hinged front gate. Cover the sides with chicken wire to prevent rodents from entering. Since this style of bin has an open top, use a tarpaulin or cardboard to protect your composting pile from the rain

Pre-made Composting Bins

Shop-bought composting bins are either ready-made or easy to assemble. They are available in a range of sizes and uses, with some offering practical features such as ventilation or extraction hatches for removing compost. Composting bins can even be a decorative addition to your garden space.

Composter Tumbler

Oxygen is an essential part of aerobic composting. Regular turning of your compost heap can help speed up the decomposition process. Compost tumblers are designed to facilitate aeration and mixing. In general, forking through your compost pile periodically is sufficient to create compost successfully. Although a tumbler may be a good option for those who find it difficult to turn their compost. Consider that compost tumblers work best if all the material is added at once, rather than in small amounts over time.


A wormery, also known as a vermicomposting bin, is a specialised container designed for composting organic waste using worms. These bins provide a controlled environment where red worms break down kitchen scraps, converting them into nutrient-rich worm castings. Wormeries typically consist of multiple layers to accommodate the worms and composting materials. They are compact and suitable for indoor use, making them suitable for households with limited space.
