Types of compost bins

Compost bins come in many materials and styles.

Common varieties include:

  • Fixed plastic outdoor compost bins
  • Outdoor compost tumbler (single or dual chamber)
  • Wire mesh compost bin
  • Worm composters
  • Indoor compost bin (plastic or stainless steel)

Indoor vs outdoor compost bins

Outdoor compost bins are usually larger, as they hold more material. They are generally much more robust and will usually have a lid that prevents smells from escaping, along with holes in the base that promote aeration.

Some outdoor compost bins allow you to spin the contents so that oxygen can circulate through and help break down the waste faster. These are called compost tumblers.

Indoor compost bins tend to be smaller so they can fit on a kitchen bench or under the sink.

Indoor bins also have lids to help prevent smells from escaping and often feature a charcoal filter to absorb some of the odor.

Single vs dual compost tumblers

Compost tumblers are large cylinders with a door on one side for loading scraps and other organic material. They are spun to mix the contents and increase aeration.

With a dual-chamber compost tumbler, you can continue adding material to one chamber while the other chamber breaks down the material.

A single chamber compost tumbler allows to to only make one batch of compost at a time.

Size and capacity

The size and capacity of your compost bin are important considerations.

Larger bins generally mean more compost can be made at once, which will save you time and energy in the long run.

If you have a small space to work with, however, consider getting a smaller bin that will require emptying more frequently but won’t take up as much space in your home or backyard.

Ease of use

Look for a bin with a large lid. It should be easy to remove and replace.

Choose a bin that’s easy to assemble and disassemble. Compost bins are usually made from plastic or steel and often require home assembly.

Choose a bin that will fit somewhere with easy access. If you will place your bin outdoors, you may want it fairly close to the back door.

If you’re looking for an indoor bin, do you want one that will fit under your sink?

Style and appearance

Compost bins come in many different colours, shapes and sizes. Some are tucked away out of sight; others blend into the landscape.

You’ll need to consider how you want your compost bin to look in your yard or kitchen before choosing one.

How does a compost bin work?

Composting speeds up the natural process of decay, as decomposition is accelerated in an enclosed space. It is the process of breaking down organic materials into rich soil that can be used in gardens or to improve your lawn.

Composting has many benefits, including diverting trash from landfills and reducing your need for fertilisers.

There are three main elements to composting: nitrogen (green materials), carbon (brown materials) and air. In order for your compost to work properly, you’ll need all three elements in some proportion.

If it’s too wet or too dry, you need to add more of one ingredient until it works properly.

What can go in a compost bin?

When you’re looking for a compost bin, it’s important to know what can and can’t go in your bin. The general rule of thumb is that if it’s organic, then you can put it in—but there are some exceptions.

Common compost bin materials include:

  • Egg shells
  • Coffee grounds and tea bags
  • Grass clippings and leaves
  • Fruit and vegetable scraps
  • Shredded newspaper (or unbleached paper)
  • Straw and sawdust

FAQ

Does a compost bin need sun?

Sunlight helps break down the compost and accelerate the process. You’ll want to keep your compost bin in a sunny place for the best results.

Does a compost bin need a bottom?

You can compost without a bottom, but it’s not recommended. Compost bins need to be able to contain enough heat in order for the material inside them to break down properly. The bottom of your compost bin serves this purpose by raising the temperature inside the bin and keeping moisture levels stable.
