Different Types of Composters

When it comes to composting, the options are endless. The goal is always the same: turn food scraps and yard waste into nutrient-rich compost for your garden. The method, however, changes based on what best fits your lifestyle. Let’s take a look at the different kinds of composters available.

Outdoor Bins

There are several different types of home composters and all have their pros and cons. First, you can get a simple compost bin for the backyard. These are often made of strong plastic or sometimes stainless steel and they’re often in the shape of a large bin or barrel.

Some are completely standard and are hardwearing containers without a lid. Others come with an airtight sealing lid to keep out pests and encourage decomposition. Outside composters often have several access points like a door on the side or near the bottom so you can easily harvest your compost. This is in addition to a lid on the top of the bin where you can dump in your next load of vegetable scraps and waste.

If you’re struggling with the idea of traipsing to the garden every time you make dinner or if you don’t have a backyard big enough for a compost bin, then a kitchen compost bin could make things a lot easier for you. These composters are compact in size and can be quite nice to look at.

They are either stainless steel or high durability plastic which can be easily rinsed clean. They range from very basic models which are made from one piece of metal and have filters in the base of the lid made from charcoal to trap odours or a high spec model which has moving parts.

Some kitchen composters have built in mixing devices or tumblers so the compost materials are kept moving and break down more easily.

Another composter type is a tumbler where the compost bin itself is barrel shaped and can be rolled or cranked with a handle to mix the materials inside. The benefit of this is you won’t need a shovel to mix your compost by hand as simply rolling the bin will mix your compost.

These composters usually have ventilation holes along the side so your compost is fully aerated. There are also blades or ridges inside the tumbler itself to help break the materials into smaller pieces so it turns into compost quicker. Some tumblers even come with separate chambers so you can split the waste between “nearly ready to use” and “freshly added”.

Hand-Rolled Tumbler

A type of compost tumbler can also be rolled by hand. These are barrel-shaped but rather than being mounted on a spindle and moved via a handle, the composter is low to the ground and is rolled by grabbing the sides, or by using molded handles, to mix and move the compost inside. These composters sometimes come with a tray or reservoir in the bottom to catch compost tea. Due to their low ground clearance, they can be difficult to use if you have back problems so think about putting these on a table or wall if you think you may struggle to harvest compost from it.

Ball-Shaped Tumblers

Some rolling bins are shaped like a ball and can literally be rolled out of sight! This is handy if you don’t want your compost bin to become a permanent feature in your garden or if you need to move it to cut the lawn or weed flower beds. The downside to this design is that if the compost bin gets too full, it can become difficult to move. Also, you may find it leaves unsightly patches of dead grass if it is left in one place for too long so don’t forget to roll it away.

Types of Composting

Vermicomposting uses worms to break down your food and garden waste. There are many worm composters available on the market today. You start with around 1,000 worms and as they chew through your materials, it leaves behind loam which is a type of soft, fine soil rich in nutrients. Worms love to use gritty textures like sand or finely crushed eggshells to help digest food scraps and dead leaves, so if you are planning to use these little creatures to help produce compost, you need to make sure you add some grainy textures to your compost bin.

Hot Composting

This is another great way to create usable soil from your leftovers. These compost bins have thick, insulated walls and an airtight lid which helps to retain heat from the sun and heat generated from the compost itself breaking down. These are great if you want to create a warm atmosphere. You can also use heat to quicken your compost production by putting your compost bin in direct sun.

Things to Consider


When you’re looking for a compost bin for the backyard think about where it will be located. Compost breaks down quicker when it is warm so make sure it is in an area that will get some degree of sunlight. If you need to use a wheelbarrow to collect the harvested compost, make sure there is enough room around the composter for your wheelbarrow.

Resistance to Extreme Temperatures

If you’re getting an outdoor compost bin made from plastic make sure that it is UV and frost resistant. Bear in mind your composter will be outside in all seasons and it needs to be able to withstand changes in temperature. There are special plastics that are designed for outdoor use so make sure you know what your bin is made of.

If Using Wood, Protect It

You can use timber to create a compost bin. If you go this route, bear in mind that wood is essentially a compostable material so it will need to be treated or lined with a non-compostable material to make sure it stands the test of time. Having said that, a wooden framed compost pile lined with a plastic sheet is an inexpensive way to create your own compost heap. Remember that this design will not be moveable so if you decide to redesign your garden in the future it could be a big job to take down your compost heap and move it.


With an indoor composter, think of a design that is compact so it can be hidden in a cupboard or doesn’t take up much space on a worktop. The best kitchen composters should take aesthetics and odour control seriously.  If it will be visible in your home, design is important so it fits in with your interior decor.

Pesky Animals

Keeping pests like rats, foxes or even bears away from your compost is also a consideration. With pests like mice or rats, they can even make nests in your compost heap if it isn’t secure. If you live in an area where pests will be a problem, choose a compost bin that is sealed and ideally is located off the ground.

Dos and Don’ts

Also, brush up on a list of things you can and cannot compost. There are hundreds of items that can be put in the bin, but one wrong material such as meat or inorganic waste can seriously disrupt the whole process.


If you go for a basic model, one of the best features to look out for is a charcoal filter. The natural absorbent properties of charcoal means any bad smells will be drawn out of the bin and into the filter. Although these need to be changed every six months, it is worth having them especially if you choose a home composter that is in your kitchen or basement. A sealable, airtight lid will also help prevent bad smells.

Some Make Compost Tea

Jar Of Compost Tea

Another great feature on a composter is the ability to collect compost tea. This liquid is what is collected when the compostables break down. Some models of composter allow this to be collected in a tray underneath or it can be drained off through a spigot. This is a really effective, natural fertilizer when diluted with water.

Indoor Models

If you want a kitchen composter, think about where it will go. If you have room inside a cupboard it won’t matter what it looks like. If it will be “on show” on a kitchen countertop then it is worth paying a bit extra for something that has been designed well and fits in with your kitchen decor. Automatic mixing is also a great feature of a kitchen composter as it eliminates the need for you to have to keep opening up the bin and mixing it with a fork. Plus, the fewer times you open it the better, as the smell will be kept inside.

Better Mixing and Aeration

Compost tumblers with ridges or bars inside work to break up the materials a lot quicker and easier. The tumblers with this added feature also aerate your compost which again makes it decompose more evenly.


Worm composters are usually easier to use when they have stackable trays. These trays mean your compost drops down through mesh layers so you get fine, ready to use compost at the bottom and you add your fresh food and garden waste in the top. This way, you also prevent loss of worms from digging out the compost as you can simply remove the bottom tray and harvest the compost while leaving the worms in the top trays.

Size Matters

Large Outdoor Compost Bin

It isn’t all about waiting for the compost to mature. Think about how you’ll harvest the soil once your vegetable scraps and other compostables have broken down. If your compost bin is too tall, or there is only a lid at the top, you might find it hard to dig out the good stuff. Look for features like a side opening door or more than one access point. Some compost bins have a sliding door that opens near the bottom so you’ll have easy access to the finished compost. You can also bring a wheelbarrow right up to the bin itself and easily shovel in your new compost.

How We Picked

Each type of composter needs to fit different needs. So we considered this carefully and only chose the top contender in each composting category.
