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. It is BPA free, constructed from virgin PP(Polypropylene) & HDPE (High-density polyethylene) – it’s a 80/20 blend
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.
The Aerobin 400 is featured on TheSpruce.com lifestyle website as their pick for Best Cold Climate Composter.

A 2021 addition to the Aerobin 400/200 is a clear tube and turn-off valve.
Aerobin 400 Features
- Capacity: 113 gallons (400liters)
- 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.

UNIQUE DESIGN FEATURES OF AEROBIN
Aerobin is designed based on how the nature decomposes the organic waste with oxygen in presence, forest bed is a perfect example, people always smell earthy and soil smell instead of the odorous smell which normally happens in our rubbish bin. The key difference between two situation is because of oxygen. So how Aerobin gets air from outside into Aerobin and also ensure the air can continuously circulate within the Aerobin?
We achieved this based on the chimney affect (hot air raises). In other words, when the biomass in the process of composting, the temperature inside of an Aerobin will be hotter than outside. So the cooler air will be naturally drawn into the bin through the base and the centre lung and naturally hot air rises to the top through the biomass. This is how Aerobin can claim composting does not require extra human intervention such as turning or mixing the compost with new material at a regular basis. Simply put balanced organic waste in and harvest from the bottom section of Aerobin’s two access doors.
AEROBIC COMPOSTING PROCESS REQUIRES 4 ELEMENTS BY NATURE – NITROGEN, CARBON, MOISTURE AND AIR.
- Compost without carbon (carbon can be brown leaves, ripped cardboard, scrunched newspaper, wood chips, shredded paper, saw dust, paper made of packaging materials) & you’ve got a one way ticket to a stinky slime festival. FYI- if you only add food scraps without carbon your compost will release methane.
- Compost without nitrogen – (nitrogen should be diverse organic food scraps, garden prunings (small pieces), grass clippings, coffee grinds), you’ve got yourself a load of carbon that going to stay exactly as it is.
- Compost without oxygen – you’re headed towards an anaerobic mess – generally accompany with stinky smell and wet mushy materials.
- Compost without moisture – moisture should come from the nitrogen inputs, generally speaking user does not need to add additional water if the nitrogen content is sufficiently added.
- Diversity of carbon and nitrogen will enhance compost process.
TO SET UP BEFORE COMPOSTING
You may want to elevate your bin on a solid and levelled platform, this can protect Aerobin from potential rodent attacks and easier to collect leachate.
- If you have matured compost lay them on the bottom because of beneficial bacteria it carries
- If no compost available, you can lay some wood chips or sticks ( no more 20cm length) for about 20-30cm high, this gives Aerobin good density to allow the air comes inside
- And then lay some dry leaves or smaller pieces of cardboard or shredded office paper another 10-20cm high
- After this you can start putting balanced carbon and nitrogen materials
HOW TO ACHIEVE AN EASY AND REWARDING COMPOSTING RESULT
We believe composting is a managed process, Aerobin can certainly reduce consumer a lot of effort to manage their composting process compare to other composters (e.g. No regular turning and mixing of the biomass is required with Aerobin). To maximising Aerobin’s contribution, consumer is encouraged to put a little effort when placing the right size (as small as possible) and balanced nitrogen and carbon material into Aerobin and in turn consumer’s composting experience will be much easier, convenient and rewarding.
HOW TO LOAD MATERIAL IN:
- When you have a bucket load of kitchen organic waste ready
- put them in a large tub/container
- Grab two full handful of shredded paper put them in 1st if shredded paper not available, any carbon materials (dry leaves, cardboard, egg tray cartons, toilet paper rolls, online shipping paper based packaging materials, wood chips and sawdust etc) will do but ensure they are torn down into smaller pieces
- mix both carbon and nitrogen well with a handy tool such as a small shovel or small garden 3 prong fork
- then load them into Aerobin without the material hitting the centre lung as they are dropping into Aerobin.
- this way, you will not be creating a lay of wet and lay of dry material, it also creates a good and balanced food source and environment for microorganism to work on the biomass easily and conveniently (carbon materials provide the low density for air to flow better with biomass and also absorbs moisture well as the liquid travels down.)

Aerobin Composter Questions
Where is the best location for Aerobin 400? Does it need full sun or does it work as well in shade? I have a nearly fully shaded area I’d like to put it, but also a spot with 2-3 hours of sun.
J.K. | 5/10/23
Hi J.,
Your Aerobin can be placed where ever it’s convenient for you. Keep in mind, in a sunnier location, and in warmer climates the Aerobin will heat up faster. You may need to add water occasionally to keep it from drying out. You want to keep it as wet as a wrung-out sponge for the decomposition process to continue and turn into dark, rich compost..
If you place your Aerobin in a shadier area, the decomposition process will take longer and won’t dry out as fast so you may have to add more carbon material to keep the moisture level as wet as a wrung-out sponge.
So depending on the climate you live in, some shade on your composter in warmer climates and more sun in colder climates would be a good balance.
Thank You,
