15 of the best garden compost bins in 2023
200L Aerobin Hot Composter
The innovative Aerobin was invented in Australia to accelerate the composting process in a natural way. It has a special core, which circulates air to support the microorganisms feeding on the waste. Thanks to the clever design, it’s one of the best compost bins for fast decomposition; you should be able to see compost forming in just 8-12 weeks of using it.
At 117.5cm tall and 51cm across, this bin can hold a lot of material. And, as it comes in an attractive ‘Brunswick Green’ colour, it should fit in nicely among trees and foliage in your garden.

Blackdown Beehive Wooden Composter - 6 Tier
Compost bins can be fairly unsightly at times, but this clever option from Blackdown hides its function by masquerading as a beehive. It’s constructed with attractive British redwood timber, and each plank is 22mm thick. It's also been pressure treated for a 15-year guarantee to give it that added longevity.
The roof attaches to the body of the bin with hinges and a sash cord, so, after opening it, you can keep your hands free to tip in your waste. Plus, there’s a handy door at the base to access your compost.
315L CompoSphere Rollable Tumbler Composter
Here’s a product you may not have seen before. The CompoSphere Rollable Tumbler has a circular shape so you can quickly churn up the waste inside. It’s also one of the best compost bins for easy transportation, as you can push it around the garden rather than keep it in one spot.

With a capacity of 315L, this compost bin can hold a large amount of household and garden waste. And it’s made from recycled, UV-protected plastic, so it should stand the test of time.
Lacewing Hazel compost bin - 900 Litres
If you’re after an understated compost bin to blend into your garden, why not opt for this attractive woven one, made from hazel? When set up, it measures 90cm across and 1m tall, so it should hold up to 900L of material.
While it doesn’t have the aeration technology of some other compost bins, air can get in through the gaps in the hazel weave, supporting the decomposition of waste stored inside.
Green Cone Waste Digester
The Green Cone is a twist on the standard compost bin. With its sleek design, which widens towards the base, it’s a more modern option for anyone who wants to create a minimal, uncluttered look in their outdoor space.
The bin is made up of a basket installed below ground level, as well as a green outer shell and black inner cone on top. It also comes with a kitchen food waste caddy and a sachet of composting ‘accelerator powder’.
Lacewing Easy-Load Slotted Compost Bin
This 1,000L-capacity unit is one of the best compost bins for people with big gardens who find themselves producing large volumes of waste. It’s made of pressure-treated pinewood, that has been guaranteed by the manufacturer to last for 15 years against wood rot.
But the key to this compost bin is the removable slats, which helps you adapt it to suit the size of your compost area, and make adding and removing from it much more convenient. It’s also available in 373L, 605L and 893L sizes.
Symple Stuff Compost Bin
This mesh compost bin is made of powder-coated steel and is both rust and corrosion-resistant. Those mesh walls allow for plenty of oxygen to enter the compost, although it will retain a lot less heat than the plastic and wooden options on this list. Each of the bin’s sides can be simply removed by unwinding the coiled wire on each of the four sides.
A simple, straightforward choice - and one that’s ideal for composting with leaf mould.

Bacsac Compost bag
Not strictly a bin, but we’re including Bacsac’s range of compost bags on our list as they’re aimed at people with limited space such as a balcony. The geotextile cloth is breathable, meaning it will keep the compost well-contained, but will still allow oxygen inside to assist the decomposition process.
We’ve featured the small 20L option here, but it’s also available in 40L and 80L sizes.

Krikoris Garden Thermo Compost Bin
Basic plastic composters keep their contents unventilated, meaning they have to be opened and the compost turned over to properly aerate. It can also be a real pain removing the compost when it’s ready.
The Krikoris bin, however, comes with a range of user-friendly features: its sides are ventilated, and there are latched lids on both the top and one side. You can also set it up on four little legs, so liquid can drain from below. If convenience is a priority for you in your garden, give this one real thought.

Wiggly Wigglers Urbalive Worm Composter
Another smart solution to composting in smaller spaces is to invest in a wormery, like this 20L kit from Wiggly Wigglers. The idea might sound a little off-putting, but there’s a reason that the waste worms produce is known as ‘black gold’.
This kit contains a stone composter along a bedding block, some lime mix, a moisture mat and, of course, 500g of composting worms. A guide is also included, and the brand has a YouTube channel to help teach you in the ways of worm composting.

Roesler 328L Compost Bin
Another wooden unit; this one with a pitched roof will keep the elements out of your compost.
Unlike the Lacewing, it only has a single removable slat at its base. It’s also pressure-treated to stand the test of time, although the makers do recommend you spray the compost bin with water in the hottest months, in order to avoid small cracks as the wood regains its moisture later on.

Meridian Compost Tumbler
A tumbler is one of the best compost bin designs out there as it helps you physically churn your compost and protects it against rodents. Scurrying little pests do often like to break into compost bins, so a way to avoid this issue is by keeping your compost up on stilts in a tumbler, and turning it periodically.
This option from Sol 72 Outdoor is made of ventilated plastic, and has two separate compartments.

How to choose the best compost bin for your garden
How do compost bins work?
Compost bins work by speeding up the decaying process that takes place naturally with dead, rotting organic materials. This would happen organically in an unenclosed space too – but a compost bin creates the perfect conditions for microorganisms to break down discarded material and turn it into nutrient-rich soil. The compost will emerge over the months, or even up to a year, and you can then add it to your beds as a fertiliser.
This process is aerobic, which is another way of saying that oxygen is vital in order for those microorganisms to work their magic. A natural byproduct of the composting process is heat, and temperatures inside composts can reach as high as 75C.
As our society grows increasingly environmentally aware, more and more people are turning to compost. Even some plastic manufacturers are marketing their products as biodegradable and compostable – claims that are currently being put to the test in The Big Compost Experiment.
Types of compost bin
Unsurprisingly, they come in a range of sizes and types. You’ll find the best compost bins in each category down below, but here's a quick round-up of the main varieties:
Wooden compost bins
Wooden compost bins are generally made of slats, which allow air in through their sides - handy for assisting the composting process. Some come with a roof that keeps the rain out. One drawback to slatted compost bins is that they won’t retain as much heat as completely sealed plastic bins. But the convenience of removable slats can make a huge difference.
Plastic compost bins
Plastic compost bins are suitable for smaller gardens and outdoor spaces. Their non-porous sides mean they are effective at retaining heat, and since they don’t let in light, they prevent weeds from growing inside the compost. Cheaper plastic bins are unventilated, while higher-end choices have holes to allow air inside.
You can turn any old sack or tarpaulin bag into a composter, but far wiser is investing in a special composting bag. These are made of breathable, durable fabric that allows oxygen to enter inside, and won’t rot or get damaged by the stored compost.
Worm composts, or wormeries, are one of the best compost bin options for people who have limited outdoor space but are keen to see something useful done with their kitchen scraps. The wiggly little inhabitants of these bins break down the material and produce a nutrient-rich liquid that works as a highly effective fertiliser.
Developed in Japan, bokashi is a fermentation, rather than decomposition, process, and takes place far more rapidly - in as little as 10 days, you can have nutrient-rich material that can be added to your garden. Read our guide to bokashi for a proper run-through of what’s involved. Bokashi bins typically come in twin backs, so you can add to one bin while the other is fermenting.

Why should I use a compost bin?
There are plenty of benefits when it comes to composting, for both your personal garden and the environment.
Breaking down your own waste not only limits the amount that's thrown away, helping to manage your carbon footprint, it can also be recycled back into your green space, enriching the soil and helping your plants thrive.
