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. Now includes an updated hose and tap for 2021, see video below.

If you have the Aerobin 200 (smaller version of the 400) you can easily add some additional strength reinforcement to the sidewalls of the unit by adding a self-tapping screw to the corner braces. This step is not required by the factory, but will help with the overall stability of the unit. See images below as a guide. You may also download a printable instruction sheet.

Generally good quality.
Unfortunately several of the tabs which are required to snap the sides in place were broken off on arrival. I had to use machine screws to secure the sides together. There should really be better quality control on such an important part of the unit prior to packaging. Looking forward to seeing how it performs.

Hi, I need to move home and can I ask what’s the best way to take apart the aerobin400 and put it back together again? And would u recommend that I leave the residue in or empty it out if I move the compost without taking it apart? Thx Ada

Hi Ada,
You can take apart the Aerobin by following the steps in this YouTube video.
Depending on how much space you have to move it – you could keep it together, but I’d highly recommend removing any compost and liquid leachate that might be in the bin to avoid a terrible mess while you are moving it.
Please let me know if you have any other questions.
Thanks,
Claudia, Customer Service
Will the Aerobin work in freezing temperatures?
C.H. | 8/24/20
Please note Aerobin will keep composting at sub zero temperatures – but it will reach a point when the biomass will freeze over. When the Winter passes and ambient temperatures increase, the biomass will thaw out and the process will start again. However the more ingredients that you offer up to the Aerobin the more chance of the biomass remaining hot and fighting off the ambient cold weather.
Aerobin has insulation in the Lid & Walls that works both ways – it helps to keep heat in – as well as keeping heat & cold out.
My Mothers Aerobin is over 2 years old and has not yet produced compost. What are we not doing? It is in the sun with a Southerly exposure for most of the day. Thanks!

Hi Rose,
Four key factors affect composting: Airflow, temperature, moisture, and the organic material added to the bin. Aerobin takes care of airflow and temperature. Adding organic waste and moisture level is usually where things might go awry.
Getting a good mix of organic materials – browns and greens may be the issue. Aerobin has a compost simulator on their site here that may help you determine if you have the correct mix. This document might also give you a good idea of what and how to add materials.
Another common issue I’ve seen is that the material in the bin is not
