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!

#6 Urban worm bag
- 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.

Buying guide
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.
Capacity
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.
Type
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.
Construction
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.
