How to Pick the Best Continuous Composters?

If the composter of your choice has all of these features, listed below, then it’s the right pick.

Number of Chambers

You must get maximum value from your composter. Since the underlying factor why we need a continuous composer is to allow us to turn everyday organic garbage to compost, there is a need to settle for a composter with at least two chambers.

This will help you to alternate between a filled chamber that is still decomposing and the free chamber that is still available for more fill. This also saves time as you won't have to spend time emptying your chamber as soon as it is filled. A composter with multiple chambers also affords you the time needed to make a perfect compost, and this is because the richest compost often needs an uninterrupted timeframe where all organic materials are perfectly broken down.

Also, aside from having at least two chambers, the chambers must be designed in such a way that enough oxygen is allowed to circulate within the chambers. The more oxygen that is allowed within the chambers will determine how quick decomposition will be.


The most important feature for a composter is the material used in making it. since most composters are usually placed outdoor, there is a need to ensure that they are made from durable materials. Materials will determine how durable your composter will be. You don’t want to start changing composters yearly or bi-annually because the ones you have won’t just stop getting rusted.

Rust is one major issue this product is often exposed to and this is because of the level of humidity and gaseous heat that goes right inside of it. This heat may corrode the composer except it is made from materials specially designed to protect it from such damaging elements. The protection often comes in the form of stands being corrosion-resistant or chamber made from materials that cannot be corroded such as plastic.

Rust isn’t the only thing you have to deal with. Having plastic composters outdoor for such a long time will damage the tank except it comes with other protection such as UV inhibited feature.

Tumbling Enabled

A composter needs to have a tumbling feature that allows you to turn the stored waster within its chambers. To make a perfect compost, there is a need that the composter is from time to time turned or spin to make sure that everything is perfectly decomposed or broken down into rich and healthy manure. Without turning, you might have to start dealing with some side of stacked waste decomposing properly while so much is pretty much left unprocessed.

While people use their hands, if they can, or stick to turn and mix the fills within the chambers of the composter, there are brands out there setting the tanks of their product on a steel spin that allows you to tumble waste effortlessly. Also, watch out for the hinges that power the tumbling, they mustn't come with any hustle as they should be designed to carry heavyweight but give very light support when you try to tumble your compost.

In addition to this, composters with tumbling features help to ensure effective aeration needed in hastening decomposition within the chambers. Since most tumbling enabled composters often come with deep fins, clumps are broken while tumbling to ensure richly grainy compost.


Depending on what you use compost for, size is another very important feature you have to consider when settling for a unit. Always remember the reason why you are getting a continuous composter, in the first instance, is to hold as many composts within its chambers as possible, and to avoid stacking huge bags of waste.

Hence, you want to avoid products that come with small tanks. What this means is that you will have to constantly empty the chambers and stacking the content if it isn't needed right away. Settling for tanks with, at least, thirty-gallon capacity will be an averagely wise decision. Optimally, there are tanks than can take even up to sixty to a hundred gallons for large compost production.

Easy to Setup

You don’t have to hire professionals to help you in setting up your composter. They should come with very simplified manuals and less disjointed components that are easy to fix and install. When the product is easy to install, it saves you time and money.

It is important, also, that your composter is not so heavy so that you can self-position it anywhere around the house without needing help. That is why most of our top products are made from plastic, to aid flexibility and easy movement.


Continuous composters are the modern way of recycling your organic wastes into usable compost. They also help to keep the house tidy but to maximize the many benefits that continuous composters have to offer, you will need to settle for the best.

Often, the best continuous composter isn't determined because of money but because of the function and features it has. That is why we have gone through the trouble of bringing to you our top six products. Each of the reviewed composters will not only help you achieve a super fine compost generation but also will satisfy you in terms of durability, appealing aesthetics, and functionality.
