13 of the best compost bins: which type is best?

Which type of compost bin is best for your garden - a homemade bin, plastic bin, hot composter or wormery? Find out, in our composting guide.

Composting your kitchen and garden waste is not only useful for keeping your garden healthy, but it also benefits wildlife and the environment, too.

Your food and garden waste enters a compost bin and then will break down over a year or so to reveal fresh, home-made compost. Compost is full of the nutrients your plants need so it is an ideal fertiliser to use and you can either use it as an organic mulch around the base of shrubs and trees, or dig it in as a soil improver.

Below, we go through exactly what to put in a compost bin before offering guidance on how to choose the best garden compost bin for you.

There are many types of compost bins available, which are explained in the above video as well as detailed below. The styles range from those you can make yourself, to at-home wormeries which let wildlife do the hard work for you. Every type of compost bin is different and will have its own benefits, depending on what you are looking for.

Following our short guide, we have also included a suggested list of compost bins which cover a range of styles, sizes and price ranges.

If you are new to composting or would simply like some more practical tips and information, see our guides on how to make compost, how to turn your compost and how to make a composting trench. We also have a handy trouble-shooting video on common problems with composting. Start composting at home and watch your garden flourish!

How to choose the best compost bin

When choosing the best garden compost bin for you, there are a number of factors to consider. These include the size of your plot, the design of your garden and the amount of compost you are hoping to produce.

Firstly, how much space do you have available? Compost bins come in a variety of sizes and with a range of capacities. You will therefore also need to consider how much compost you would like to make and how quickly. If you are not prepared to wait a year for your first batch, there are compost bins which can speed up the process, as we explain in more detail below.

The type of ground you are setting your bin on is also important, as some types will ideally need to be placed on grass or earth while others can sit on hard ground.


Types of compost bins

Compost bins come in a variety of shapes and sizes, and are made using different materials. Here, we explain the different types of compost bins along with the conditions and tasks they would each be suitable for.

Make your own compost bin

You can make your own compost bin using wooden pallets or corrugated iron. Enclosing the sides will retain heat, speeding up the rotting process. The larger the pile, the more heat. The ideal minimum size is 1m x 1m and, ideally, make more than one – it makes the compost easier to turn.

See our guide on how to build a compost bin.

Plastic compost bin

Turning compost from plastic compost bins

A plastic compost bin is ideal for a small space. The plastic sides and lid retain moisture and heat to encourage rapid decomposition. They also block out light to stop weeds regrowing. The bin should ideally be placed on grass or earth.

Hot composting bin

Insulated with a close-fitting lid, hot composting bins are designed to allow decomposition at a much higher temperature and a higher speed (30-90 days, compared to around six months for ordinary compost) and result in a finer compost. They are roughly the size of a wheelie bin and can stand on a hard surface.

Wormery compost bin

Wormeries are designed for the small-scale composting of kitchen waste. Worms mix and break down the compost quickly and produce a nutrient-rich liquid for use as a fertiliser. Compost worms can also be added to larger bins. Not all waste can be composted, so you’ll still need a compost bin too.

Read our guide on how to set up a wormery.


What to put in a compost bin

There are a whole range of kitchen and garden waste materials which can be put into a compost bin. The only exception are wormeries, which are designed for smaller scale food waste only.

For the other types of compost bins you can throw in leaves, grass, garden clippings and any vegetable waste, ranging from potato peelings and even coffee grounds. You can also add black and white newspapers, sawdust and wood shavings. The key is getting the ratio of green to brown waste correct, which you can discover in our compost guide.
