The Aerobin is a technological breakthrough in home and garden
waste management. Here are answers to a selection of frequently-asked
What is it?
Aerobin is the revolutionary new home and garden waste
containment system that allows households to effectively recycle
organics at home - for the first time – which assists to save
How does Aerobin help save the environment?
Using an Aerobin helps the average household divert 50%
of their waste away from landfill, into compost. Aerobin composts
aerobically, a decomposition process doesn’t give off the potent,
dangerous, greenhouse gases that occur when organic waste is decomposed
anaerobically in landfill. This means by composting in an Aerobin,
you are reducing your household carbon emissions. The organic
compost and diluted leachate produced by the Aerobin can be used
as a natural soil conditioner in the garden. Using compost also
helps save water in the same way as putting mulch on your garden.
Where was it designed?
Aerobin was invented and designed in Australia which
has wide-ranging climates from very hot in summer to very cold
in winter especially in the southern, mountainous areas. But it
has been designed to work in all climates, even in winter, by
incorporating integrated thermal insulation into its double-skinned
walls and lid.
What can I put in it?
Aerobin will take home and garden organic waste. Vegetable
peelings, food scarps, soft green garden prunings, lawn clippings,
newspaper, leaves and so on. See “What can go in the bin?” on
the instruction leaflet accompanying each new Aerobin for more
Can I put meat, citrus, onions in it?
No meat, because Aerobin operates on the basis of aerobic decomposition, and meat, any food that is cooked or processed will not decompose aerobically. Citrus and Onions
are fine, both will compost faster if roughly chopped before placing
into the Aerobin.
How long does the compost take to break down?
Aerobin will create the first compost in about twelve weeks
from the time material is first added to the bin; however it is
a continuous cycle feeding from the top and taking compost out
of the bottom, all year round.
What is leachate?
Leachate is the collected moisture that drains from the compost
as it decomposes, and is collected in a leachate tank contained
in the base of your Aerobin. Compost is like a sponge, and as
its mass reduces, it cannot hold all the moisture it originally
held. Leachate can be a rich source of micro-organisms and mineral
nutrients for your garden.
What do I do with the leachate?
Leachate can be drained directly onto the garden or watered
onto flower beds via a watering can. Leachate however must never
be used in a spray as airborne particles could cause respiratory
problems. Observe appropriate handling precautions.
How do I get the compost out?
Access panels are provided at the bottom of the bin at both sides.
Lift the panel vertically, using the handle, to unlock, then pull
the unlocked panel outwards and away from the bin. When replacing
the panel, take care to first push it in, then downward firmly.
A slight click will be felt as the panel locks, which prevents
unwanted entry by pets or vermin.
Can I put animal faeces in it?
In most jurisdictions it is illegal to put carnivore (meat
eating animal) faeces in the Aerobin. However, herbivore (grass/plant
eating animal manure e.g. horse, cattle, goat, sheep, poultry
manure etc) can be included. It must be remembered that all animal
faeces may carry pathogens, as may all finished compost, and appropriate
precautions should be always be observed when handling. See the instruction leaflet accompanying your new Aerobin for appropriate handling precautions.
How do the worms get in?
Aerobin doesn't actually need worms to operate and will break
down organic waste material without them. However worms are good
for all composting and the small holes in the bottom of the Aerobin
may allow worms to enter.
Will it kill worms?
Worms may die if placed in the top of the bin due to the high
temperatures that may occur with aerobic composting, however,
worms should survive and thrive at the bottom of the bin and will
greatly enhance the composting process. The wonderful thing about
the Aerobin is that you do not need to look after the worms or
worry about leaving them alone when you go on holidays.
Does the lung turn?
erobin has a static lung that is designed to allow passive ventilation
throughout the whole composting mass, so no turning or churning
Does it need to be hooked up to a power source?
Aerobin works on the natural effect of micro-organic aerobic decomposition
and does not need anything other the addition of your organic
kitchen and garden waste.
How do the micro-organisms get in?
Micro-organisms exist everywhere, all around us, in the air, in
the home and garden, so they will already be in the Aerobin, as
well as on any organic materials you drop into the Aerobin. You
can increase the micro-organic content within your Aerobin by
adding a small amount of blood and bone, or manure, but it is
not essential to do so.
Do I need to keep it in the sun?
It’s not necessary. In fact, to prolong the life of the plastic
materials, your Aerobin should be placed in shade or partial shade.
The heat inside the Aerobin comes from the micro organisms breaking
down the organics, not from the sun. The integral insulation keeps
that heat inside – even in cool climates.
Why do other compost bin makers say their bin must go in the
sun? Probably because their bin does not work well enough
for the micro-organic activity to generate optimal composting
temperatures. With an Aerobin, there’s no need to worry, because
micro-organisms will thrive when they get plenty of air, and that’s
one of the core principles behind the Aerobin design.
Apart from airflow, what else is important for successful
Four key factors: Airflow, temperature, moisture, and the organic
material added to the bin. Aerobin looks after three of the four
factors itself. The fourth factor, adding organic waste regularly,
is up to you.
How does Aerobin look after those key factors?
Because of the patented aeration core, Aerobin consistently maintains
temperatures between 50 and 70 degrees Celsius when composting
freshly-added materials. Because Aerobin recycles moisture and
does not let it escape, moisture levels are better maintained,
promoting faster composting. University tests have shown Aerobin
maintains moisture content between 50-60% RH. Levels below 30%
constitute an OH & S risk, due to the possibility of fungal spores
and micro-organisms becoming airborne.
How does it kill most weeds and seeds?
Aerobin uses a natural process of aerobic decomposition using
aerobic micro-organisms which naturally produce temperatures of
up to 70 degrees, provided enough organic waste, oxygen and moisture
is present within the system.
It really breaks down newspaper?
Aerobin will breakdown all organic waste which includes newspaper
and cardboard, Newspapers and cardboard should be either screwed
up or preferably shredded. If adding a lot of newspaper at one
time without any moist vegetable or plant matter, some water may
be sprinkled on top of the newspaper, just enough to dampen it
Where can I get one?
Please email email@example.com
Do I need to situate it on bricks?
Aerobin can be located on any flat surface, if it is located on
a brick base, make sure whole of the base of the Aerobin is supported,
not just around the perimeter. A full Aerobin may weigh up to
What other sizes are available?
Aerobin comes in the one convenient size which is designed
for an average household with a garden. It is large enough to
accept the output of a busy gardening session, but small enough
to locate conveniently in your garden.
How long will it take me to fill it?
Aerobin will take up to 400 kg of organic waste at one time, but
the process is continuous, and studies show the Aerobin should
be able to cope with up to 3.2 tonnes of organic waste a year,
far more than the average household will produce.
How come they are so cheap?
Aerobin is been provided direct to the public to provide the lowest
possible price as we believe everyone can play a part in saving
Can I take it apart to relocate it?
Aerobin is designed to be child proof and locks together so children
and pets cannot take it apart, possibly spilling the compost.
Therefore, the initial location should be carefully selected.
However, when emptied, the bin weighs only 26 kg and should be
quite easy to relocate.
Does the driver assemble it for me?
Aerobin is designed to be assembled easily by customers, however
if you do find it too difficult then a service call can be arranged
at a cost. Remember to read the instructions before starting to
assemble. Assembly should take about five minutes.
How long is the unit guaranteed?
Aerobin is guaranteed for 3 years against manufacturing or
Is it guaranteed to make good compost?
Aerobin has been tested against leading composters around the
world and worked the best, including creating great compost measured
to Rottegrad 4 standard (one step down from the top level) after
just 13 weeks. The test indicated Rottegrad 5 standard would be
achieved given a little more time.
How long will it last?
Aerobin is made of UV stabilised plastic, and like similar products
like wheelie bins and milk crates made from the same sort of material,
the Aerobin will last for years and years, but actual life will
depend on a number of factors including where it is situated.
Can I put dairy products in it?
Aerobin works on the aerobic process in which odour is minimised,
unlike the anaerobic process that occurs in landfill, when material
becomes slimy and smelly. However, even with an aerobic process
dairy products can give off an unpleasant odour when decomposing,
and should only be used where the smell will not offend anyone.
It’s better to avoid them to avoid the problem.
Can I put magazines in it?
Unfortunately due to the inks and paper used, magazines are not
recommended unless specifically marked as biodegradable.
Can I keep it inside?
Aerobin uses an aerobic process which means plenty of airflow
is required, and if kept indoors a composting odour may be evident,
so it should be kept outdoors.
Does it take lawn clippings?
Aerobin is ideal for composting lawn clippings, as well as all
green garden and kitchen waste. Blood and bone should be added
to provide further nutrients, and shredded newspaper to balance
the moisture content, if lawn clippings are the only form of waste
available for composting.
Can I put ashes from the fireplace or barbecue in it?
Yes, provided the ashes are cold. Hot ash will damage the plastic
and void the guarantee. Too much ash will slow down the composting
process too, so add ash sparingly and interspersed with vegetable
What if I break a piece of it accidentally - can I get spares?
Aerobin is exceptionally resilient and should not break unless
mistreated, however, in the unfortunate event of a part being
broken, replacement parts can be provided at a charge. Please email at firstname.lastname@example.org
If I buy two how much is the price?
Twice the price of one unit.
How many do I have to buy to get a discount?
The price of the Aerobin has deliberately been made very competitive
to ensure most households have an opportunity to buy one and to
take the first step towards a more sustainable way of living.
The list price applies for all consumer quantities, however, special
pricing applies for quantities in excess of one thousand units
for local government organisations. For more details on volume
pricing, please email at email@example.com
How much leachate can the tank hold?
Aerobin has a 15 litre leachate tank underneath as part of the
integral design of the bin.
How long will it take to fill the tank with that much leachate?
It depends on the moisture level of the materials you put
into the bin. You might expect with average moisture content and
a balanced mix of wet and dry materials, the leachate tank could
take two or three months to become full. It will fill faster if
you add more kitchen waste which contains more moisture than,
say, newspaper or leaves from the garden.
How do you get the leachate out?
Leachate contains micro-organisms and should be used carefully
and in compliance with the safety guidelines. Refer to the instruction leaflet accompanying the product for
information on safe handling of leachate. To access the leachate,
connect a piece of ½-inch garden hose to the outlet situated
at one corner of the base of the Aerobin, and lead the other end
away downhill into a low, flat dish, or watering can. Rotate the
external outlet housing until the leachate flows. Rotate back to stop
Does the leachate tank get sludge in it?
Some sludge may build up over time, the residue of small
particles of organic material. The leachate tank can be flushed
once or twice a year by attaching a hose to the outlet and letting
the water flow for a few minutes.
Do I need two bins?
Aerobin has been designed to accommodate the organic kitchen and
garden waste from an average household with a garden. More bins
may be required for larger size families, strata titles and larger
size gardens or properties.
