Aerobic composting means composting with air. The opposite of this, without air, is anaerobic composting. Organic matter is turned into compost by micro-organisms living in the composting material (biomass). Giving these micro-organisms the correct environment means they can work quickly and effectively.
- An aerobic compost bin, under the correct conditions creates a lot of heat, this can kill all sorts of seeds and pathogens.
- An efficient aerobic compost bin does not emit a foul ammonia like smell.
- An aerobic compost bin reduces the biomass to a usable compost quicker than its anaerobic counterpart.
Most garden compost bins or heaps operate in an aerobic fashion, or try to. Traditionally this has been achieved by forking the compost heap, turning it or moving it into another container. All these actions mix the materials and introduce air.
Introducing a large mass of material such as lawn clippings can cause a normally aerobic compost bin to go partly anaerobic. It's always a good idea to have some carbon rich material to help break up large volumes of green material - see our guide on adding compostable material to your Aerobin for more information.
The Aerobin has a number of features that enable the aerobic micro-organisms to thrive. These include an insulated container, moisture recirculation and the aeration lung. Simply adding the correct mix materials in layers is all that is required. No turning, no mixing. The waste is reduced to rich compost and leachate (compost tea) in a very short time.
