The First Composter Which Requires No Extra Work - No Turning Required
The Aerobin 400 uses a patented lung® or aeration core inside a sealed bin to promote aerobic break down of organic matter, which experts say is the preferable method to reduce greenhouse gas emissions.
The thermal insulation in the Aerobin 400 conserves heat, leading to rapid breakdown of the biomass and works efficiently year round, even in cooler regions. There is no need to turn the biomass and it is pet and rodent resistant. It has little odor and can kill noxious weeds and seeds.
The Aerobin 400 is easy to use - just open, drop and close. After a short time, fertile compost is produced, which is easily accessed via the lower side door.
The Aerobin 400 comes with a reservoir at the bottom to collect the leachate, which when diluted makes for great "compost-tea" liquid fertilizer.
- Capacity: 400 liters, 113 gallons.
- Insulated side walls and lid for year round operation - both to retain heat generated by the aerobic composting process and stop cold ambient air reaching the biomass.
- It has a base and a Leachate Tank for collection of liquid nutrients dispelled from the biomass (green waste).
- No turning or agitating of the biomass is necessary - simply drop and forget!
- Aerobin requires no accessories or tools.
- It's vermin resistant.
- Aerobin composts kitchen & garden waste quickly.
- Moisture recirculation system.
- Aerobin lowers GHG emissions.

PROS & CONS
- Unique patented self-aeration lung means you don’t have to turn the compost manually
- Double wall insulation with polystyrene means it is protected against cold weather
- Very easy to assemble
- Sturdy and it doesn’t fall over or blow away due to the heavy-duty construction
- It creates a lot of heat and keeps the compost warm
- The plastic can warp and change shape in very hot weather so it may not be suitable if you live in a very hot climate
- It does take a long time to break down the compostable materials
- Some users have found they need to mix the compost manually, especially if it has woody items like twigs inside
- Hard to turn the spigot to drain away water and the spigot itself can become blocked
- Very tall design so it is difficult to dig right down to the bottom of it
Compost will be ready after 3 to 6 months of regular use, but some users have said they have seen results in just over a month — turning the compost manually speeds up the process.
You can easily check the compost by removing either of the 2 side access doors. If you take a peek and the compost seems to be damp, darkly colored, and even in texture, it is ready for use!
DOUBLE WALL INSULATED DESIGN
An insulated composter will help your materials become “hot compost” and break down quicker. As anyone who has left a cup of tea for too long knows, everything will cool or heat to the temperature around it. Put your tea in an oven and it will heat up, leave it outside in sub-zero temperatures and it will freeze. With an insulated compost bin, heat is produced when the compostable material breaks down and the insulation keeps that heat inside the bin instead of it escaping. The thick, double wall insulation uses polystyrene to keep this heat and uses it to break down the compost itself.
Good hot composting needs around 40 to 60 degrees heat. So when you’re putting the composter in your garden, think about where it will be. In a cooler climate, try to put it somewhere in direct sunlight so the bin itself will be helped to keep warm.
In a very big compost heap, you’ll find the centre will be warmer than the outside. The compost should be turned regularly to make sure the cold waste on the top and outsides is mixed into the hotter centre. The average household produces about five kilograms of food waste a week. Add to this a bag of grass cuttings in the summer when you’re doing more gardening and you could have around 15kg every week in your bin. To keep your compostables hot, you should make sure you’re adding around 10kg a week.
HEAVY DUTY CONSTRUCTION
This bin is designed to be installed in your garden and left there. This is great but it means you must have something which can withstand everything Mother Nature throws at it! The Aerobin is designed with heavy duty plastic covering and is billed as being able to withstand gales, cold temperatures and boiling hot summers.
The last thing any composter wants is to come out after a heavy storm and find half rotted vegetable peelings scattered across the garden as the bin has been knocked over by the wind. Equally, foxes or other garden visitors may knock a less durable bin over and get at the contents so making sure your bin will stay sturdy is very important.
The Aerobin has a lid which means you can completely seal the compost heap – helping to deter pests and keep the heat in.
TWO DOORS TO REMOVE COMPOST
These doors also help you gather the soil into a wheelbarrow so you can carry it around the garden to spread on flowerbeds or in pots. The barrow can be put in front of the bin and the compost shoveled out at waist height rather than having to kneel down to the floor or dig down into the bin from the top and lift it down into a bucket or barrow.
The door itself also lifts off completely which makes it easy to get a fork or shovel into the bin itself and harvest your compost.
Most buyers find the Aerobin 400 to be fairly easy to assemble and can put it together in an hour or so, with only one person. There are no tools needed.
There can be some confusion as to which parts go together, as they are not well labeled, and some may have difficulty attaching the panels together.
It’s definitely worth checking out the instructional video on the assembly in order to get some context as to how everything goes together.
The Bottom Line
Overall, the Aerobin 400 composter is a pretty solid good purchase for home composting needs. If you want a high quality, large capacity ground-based bin, this is perhaps the best out there, though the drainage tape design is not ideal.
It is able to hold a large amount of material and keeps rodents out while keeping heat in, even when the temperature is low outside. Many users have had great results with the quality of the output after 4-5 months and their end result seems to be worth the minor tweaks needed.
