Best Compost Bins 2021

Composting is one of the easiest ways you can reduce household waste. It’s easy to do, requires very little work, and can be done indoors or outdoors. It’s also very useful to gardeners since compost is one of the best ways to add the rich nutrients that plants love to your soil! You don’t even need a yard to compost, but you will want the best compost bin.

In this handy guide, we go over some of the highest-performing compost bins available. Included on this list are all the major types of composters, include tumbling and stationary bins. If you’re looking for the best compost bin, you’ve come to the right place.

Things to Consider

The most convenient way to compost is to keep both a small bin in your kitchen, which is only about a gallon or so (which will allow you to keep several days’ worth of scraps, before dumping them into your composter), in conjunction with a larger bin. Generally, composters are designed for outdoor use, with a few notable exceptions, such as worm composters, which are great for efficient indoor composting.

The two main types of composters are stationary (or “continuous”) and tumbling. Both are available in a variety of sizes. If you have a big family, or want to generate more compost, look for a larger composter.

  • Stationary Bins. Stationary bins, which can be enclosed or open, are generally larger and also easiest to use – just toss in your scraps and yard waste, and wait to collect the compost from the bin.
  • Tumbling Bins. While stationary bins can take a long time to generate compost, tumbling bins (enclosed, elevated containers that have a mechanism or handle for rotating the entire load of compost) are great for speeding up the process. Because these require a bit more work, and produce batches, they are better for gardeners who don’t mind slightly more planning. Other composter types include stackable bins, such as worm towers.

Buying Information

In the list above, there are examples of every main composter type. To choose the best compost bin for your household, you need to consider size, type, and ease-of-use. Composters can also differ in the following ways:

  • Covered Versus Uncovered (Stationary Bins). Uncovered bins are the easiest to use. A drawback, however, is that small animals, such as rodents, can easily find their way in. Covered composters remove this problem.
  • Single Versus Multiple Chambers (Tumblers). Tumble composters produce compost in batches. Some models have two chambers, which allows you to “time” to separate batches.

It’s easy to use and rotate, and it comes ready to use – no assembly required. With 2 composting chambers, you can stagger your composting to always have healthy compost ready for use. Just alternate the side that you add your new materials into. I’d suggest a 2-3 week cycle if the bin can be placed in direct sunlight. It will work that quick.

For best results, rotate the bin once or twice a week. The large openings makes it easy to load and unload the compost. This bin has lots of holes for proper aeration and deep fins that break up and mix the compost on rotation.
