6 Best Outdoor Continuous Composting Alternatives
Updated: Aug 14
Continuous composting allows you to turn your waste into nutritious compost. It is popular and well known because it requires less work than other composting methods.
All you have to do is put some waste in the composter, wait for it to decompose and then open the other end of the bin to collect the ready compost. It is called continuous because you can easily compost on a constant basis and extract the ready compost without disturbing the fresh waste on the top.
If you keep adding fresh scraps of food waste, you will have a constant stock of compost to use in your garden. Sounds cool right?
For this purpose, I have rounded up the continuous composters that are available in the market online. All the features, reviews and specifications are mentioned under each thorough market review. To help you choose the best option based on your requirements, I have also added a buying guide at the end to help you assess the specs and choose the best one!

Now let’s look into these options individually
8 Sided dual-chamber tumbling composter
This compost tumbler has a dual-chamber design which means that you can continuously create compost. As soon as one side is full, you can leave it to compost while starting a new pile on the other side.
The chambers are easy to turn and quick to rotate. The walls inside the bin are lined with spikes to accelerate the composting process. The bin also has aeration holes to help the compost get enough oxygen, making the process more efficient. Compost tumblers give better results than home composters, if the conditions are favourable, i.e., warm/hot climate.
The compost bin is made from post-consumer recycled polypropylene, which is BPA-free and UV stabilized, so you can leave the compost bin under the sun. The bin is also elevated from the ground and has galvanized legs, making it impossible for rodents to climb up and get inside.
Reviews: Some buyers have reported that the compost bin is quite difficult to set up as there are lots of nuts and bolts. It is advised to look at the video below - the instructions are clear and easy to follow.

Feedthrough the top and collect castings from the bottom.
No separating worms from trays.
Breathable 900D oxford fabric construction.
New 2021 patent-pending design eliminates bottom zipper.
The Urban Worm Bag Version 2 turns your household waste into worm castings that produce nutrient-rich compost for your garden and yard. Composting worms tend to stay in the top 6-8 inches of their habitat.
So as you add layers of fresh household waste like food scraps, the worms will move higher, leaving their castings below. After 4-6 months, you can harvest worm-free castings without disturbing the ecosystem of worms and microbes that are hard at work at the top of the Urban Worm Bag.
Urban Worm Bag does not create compost liquid - leachate. It is suggested that as long as you keep good levels of carbon-rich bedding of dry waste, you are likely to have a thriving worm bin.
Reviews: Customers suggest that after 4-6 months, open the zipper bottom and loosen the interior drawstring. Worm castings should be worm-free and allow direct application to your garden or plant.

Continuous vs batch composting
Batch composting is very different from continuous composting. You need to make a pile and leave it untouched until the waste gets decomposed. You can’t just dip in and take compost whenever you want.
Batch composting can be done quickly as you can turn the pile and plan the ratio of brown and green wastes. The Batch composting usually involves hot composting to make it more effective.
Batch composting requires you to do some work and plan. You need to pile materials and measure them before adding them to the composter.
Continuous composters need to be managed. You can keep adding materials without thinking much. This model seems to be more practical for many people
Another advantage is that you can have to scale it as per your liking. You can also switch to worm bins for indoor composting.
When it comes to buying a composter, the first thing you want to consider is where it will be located. Once you’ve chosen a location to place it, you’re good to go shopping for one.
The size of the composter plays a significant role for two significant reasons -
Make sure that it fits in the place you have chosen.
Make sure it can hold all the waste produced.
There is no specific rule on how big your composter needs to be. These two essential factors are merely to make sure you pick the best composter.
For someone who lives in a hot place with very little waste, it is suggested to go with a smaller composter. If you live in a colder climate, the composting slows down as it gets cooler so you may need a bigger composter.
There are a few varieties of composter for continuous composting. You can decide which type is best for you.
If you want a passive compost bin where you just throw food in, opt for a traditional open bottom bin!
If you want your compost to be ready quickly, you can opt for a dual-chambered tumbler.
If you have limited space with lots of waste to process, you can choose a worm bin or dual-chambered composter, whichever suits the space and amount of waste.
The construction refers to the material of the bin. Other things that you need to look out for are aeration systems and insulation.
In case your bin is exposed to harsh weather, make sure that it is durable enough to last the seasons. Especially during cold climates, strong insulation becomes important to continue composting all year round.
Aeration is an integral part of the composting system. If it is not proper, the bin can start smelling bad. The compost needs to stay well aerated with holes in the container.
