Compost Bin 2021 Buying Guide

Benefits of a Compost Bin

Compost Bin Buying Guide
  • Enriches Soil - Composting is an easy way to add organic matter to your planters, flowerbeds, vegetable garden, and lawn. By enriching the soil, you’ll improve your harvest, create the right environment for new plants to thrive, and lower risks for diseases and pests.
  • Save Money on Chemical Fertilisers - If you’re producing enough compost, you won’t have to buy compost or soil enrichers like fertilisers, helping you save money.
  • Makes Composting Easy - Composting can be quite a chore, but not when you have the right bin! With today’s products you can install a compost bin outside, in your garage, or in your kitchen, making it easy and fuss-free to compost. 
  • It’s Great for the Environment - Composting reduces methane emissions, improves your garden’s ecosystem, lowers how much of your waste ends up in a landfill, and reduces your carbon footprint.

Types of Compost Bins

There are plenty of different compost bins on the market, and the most common types are:

Countertop Compost Bins 

Types of Compost Bins

These are small containers where you can gather your scraps before you take them outside to add them to your compost. They are fully sealed and have charcoal filters, so there’s no risk of unpleasant smells or attracting pests.

All you have to do is fill it through your week with scraps, then dump it into your composter when it’s full. These compost bins are very affordable and are usually designed to look great too!

They tend to have very good filters, so there’s no risk of smell, but they are limited in capacity.

Stationary Outdoor Compost Bins  

These are usually constructed of durable materials and are designed to create the right environment for organic materials to break down. They have ventilation, but are designed to prevent pests like rats from getting in.

These compost bins are often the most affordable type and have a large capacity. They do work a bit slower than other types and you will have to mix the compost yourself.

Compost Tumbler 

A compost tumbler is a type of outdoor compost bin

In order to make compost, you need to mix the materials every few weeks. The compost tumbler is a type of outdoor compost bin that takes a lot of the work out of this job!

It’s barrel-shaped and up on legs, so you simply use a handle to rotate the drum as needed. Compost tumblers create compost quickly, use minimal manual labour, are easy to use, and are more animal-proof than other types.

Worm Composting Bin 

Also called worm farms, these are a great option for outdoor home composting, especially if you don’t generate a huge amount of composting material. It’s made of stacked containers that have ventilation and a tap on the lowest level. 

You’ll use a specific earthworm species that loves kitchen scraps, and all you have to do is keep the containers in a shaded, cool spot (even a shed will do), sprinkle with water to keep the environment moist for the worms, and add your scraps on a weekly basis.

The worms and compost produce a liquid called worm tea, which is a fantastic fertiliser and can even be used as an organic insecticide.

They’re low maintenance, can be used indoors, take up very little space, and are a great educational tool – although they can be more expensive.

How Do I Choose a Compost Bin?

Best Compost Bins Reviews

When looking for a compost bin, take into account the following factors to help find the right one for you.

  • What You Want to Compost - If you are looking to compost kitchen food scraps, then a countertop compost bin or worm farm is a great choice.

    If you are also composting grass clippings and garden waste, you’ll need something a bit bigger, like a compost tumbler or stationary outdoor compost bin.
  • Your Composting Goals - If you want to do large-scale composting for your garden or vegetable beds, then you’ll need one or even two large-size tumblers, outdoor bins, or a combination of a tumbler and a composting pit.

    If you want to reduce your food waste, then a countertop compost bin or worm composting bin are a better option. If you want to try to bring more organic gardening into your space, a worm farm can be a great way to produce organic fertiliser and insecticides.
  • Your Location - If you live in an apartment with no garden, you can still compost using a countertop composter or worm farm. If you have a garden or large outdoor space, then an outdoor composter or large tumbler will work well.

Features to Look for in Compost Bins

Benefits of a Compost Bin

Before you buy, look for compost bins with these features.

  • Size - It’s all about finding the right size for your composting needs! Larger compost bins are great if you have a lot of organic material and garden waste to compost, but they do take longer to produce usable compost.

    Smaller compost bins can be more practical and convenient, as they produce compost more quickly. You want a size that will accommodate your waste production and create compost as quickly as possible for that volume.
  • Odour Control - Composting can get a little smelly, and that can be a problem – especially if your bin is indoors or on a balcony. Look for compost bins that feature air vents and charcoal filters to keep any odours under control.
  • Durable Construction - Compost bins can be made out of a range of materials, including plastic, wood and metal. It might not sound very eco-friendly, but a thick, dark plastic construction is often the best choice.

    You can look for a recycled plastic bin too! This is because plastic compost bins absorb heat well, lock in moisture, and create the perfect environment for organic materials to break down.

    Look for a compost bin that is rated for outdoor use, so that it will last for years to come.
  • Dual Chambers - When a tumbling composter is divided into two chambers, you get a continuous flow of compost because you can fill one side, leave it to mature and break down, and start on the other side with new organic waste.
