The Green Cone Composter Solar Compost Digester is an
earth-friendly companion to the traditional backyard composter
The Green Cone Composter System is a smart, easy-to-use, efficient
household tool, which reduces waste and eliminates most of the problem of
food disposal. It's a clean, healthy way to minimize your family's kitchen
trash while helping the environment. The Green Cone Composter is primarily
constructed from recycled materials, and the digestion basket and inner
solar chamber are made from 100% recycled plastic.
The Green Cone Composter System is designed to accelerate the natural
decomposition process by raising temperatures, maintaining aerobic
conditions, and encouraging the growth of micro-organisms. The system
processes almost all household food waste, including vegetable scraps, raw
and cooked meat or fish, bones, dairy products and other organic food waste
such as bread and pasta.
So What Exactly is the Green Cone
The Green Cone Composter is comprised of a lower basket installed below
the ground, which forms the base for an above ground double-walled solar
chamber with an access lid. The Green Cone Composter stands 26 inches
above ground level and extends 18 inches below ground level. Access is
through an 8-inch diameter hole in the top of the solar chamber, which is
sealed by a hinged lid with a security catch.
The design of the Green Cone Composter uses solar heating in the
double-walled chamber to facilitate and accelerate the aerobic
decomposition process within the digestion basket. Therefore, the system
should be installed to obtain the maximum sunlight in your backyard. The
one-gallon sealable Kitchen Compost Caddy is recommended for collecting
and carrying the food waste to the Green Cone Composter.
The Green Cone Composter will digest approximately 11 pounds of food
waste a week, which is over 25% greater than that produced by the average
household. The food waste is converted into water, carbon dioxide and a
small amount residue, without the need for mixing or turning the waste. In
a well operating system the residue will occupy the bottom 10 inches of
the digestion basket after the decomposition of about a ton of food waste.
Thus, after about five years this small quantity of residue must be
removed and dug into the garden sub-soil.
Returning Natural Products to Their Source:
While we encourage all of
our customers to explore the wealth of benefits of vegetarianism, the
Green Cone Composter takes all household food waste, including
vegetable scraps, raw and cooked meat or fish, bones, dairy products
and other organic kitchen waste (e.g. tea bags, bread, etc.). Abundant
Earth offers a convenient one-gallon Kitchen Compost Caddy for
collecting and carrying household food waste to the Green Cone
The patented design of the unit utilizes a solar heating effect between
the inner and outer cones to promote air circulation, which facilitates
the growth of beneficial micro-organisms and the desirable aerobic
digestion process. The household food waste is converted into water,
carbon dioxide and a small amount of residue. For a full technical

Green Cone Composter Technical Details
Because over 90% of the waste material in the Green Cone Composter is
absorbed safely as water by the soil, the Green Cone Composter only needs
to be cleaned once every few years when treated with care.
Once The Green Cone Composter is properly installed, it will soon become
an invaluable household tool that you'll use every day. Abundant Earth
offers a variety of products that make the Green Cone Composter System
easy to use for the entire family.
Green Cone Composter Kitchen Compost
The Kitchen Compost Caddy is a convenient accessory that is
kept in your kitchen to reduce the number of trips you make to your Green
Cone Composter. Throughout the day, food waste is stored in the caddy
before it is taken to your Green Cone Composter.
The Green Cone Composter is designed to
- 1 full caddy (1 gallon of waste) every 1-2 days during summer
- 1 full caddy (1 gallon of waste) every 2-3 days during winter
Remember to add Compost Boost Compost Accelerator during the
winter months. (see below)
Compost Boost Compost Accelerator:
Abundant Earth also offers Compost Boost Compost Accelerator.
BiOWiSH™ brand Compost Boost Compost
Accelerator is a combination of environmentally friendly active
micro-organisms and powerful blend of beneficial enzymes, super catalyzing
co-enzymes and co-factors with a remarkable ability to fully digest a wide
range of compounds and pollutants which sanitizes and leaves the
environment in natural balance. It is a natural 100% organic and
biodegradable culture that uses no harsh chemicals or residues.
Compost Boost Compost Accelerator vastly improves the Cone's digestion
process, especially when it can't enjoy a full day of sunshine, or during
the colder months of winter. Simply add the powder into the caddy before
emptying the food waste into the Green Cone Composter. It is also
beneficial to use the powder for the first week after the installation of
the Green Cone Composter to encourage the initial growth of bacteria.
Dealing with Household Waste:
The Green Cone Composter is an integral part of dealing with
your household waste. It eliminates your cooked and uncooked kitchen food
waste, including meat, fish, bones, dairy products, vegetables, fruit,
Virtually the only exceptions are bulk amounts of food related materials
that require a very long time to breakdown, namely: cooking oil/fat and
the hard shells of nuts and seafood, such as oysters and crabs.
Other household waste (i.e. non-kitchen waste) must not be put into the
Green Cone Composter, but disposed of in methods approved by local
What's Good and Not So Good for the
Green Cone Composter?
What can go into the Green
- Fish, Meat & Poultry
- All Bones
- Fruit including peelings
- Vegetables including peelings
- Dairy produce
- Cooked food scraps
- Crushed egg shells
- Tea bags
- Animal Waste (Excrement)
**see note below
What cannot go into the
Green Cone Composter
- Grass cuttings
- Hedge clippings
- Bulk oil
- Household chemicals
Food waste should be transferred as soon as practical from the kitchen to
the Green Cone Composter, which allows food waste to be removed daily.
Once deposited in the below ground digestion basket, there is no
possibility for unintentional access to the food waste by human activity.
As with any gardening activity, particularly those involving soil or
compost, gloves should be worn when removing the small amount of residue
that accumulates in the digestion basket after several years of operation.
Temperatures in the solar chamber of the Green Cone Composter reach up to
122°F for long periods during summer months. Because of these ideal
conditions, indigenous microorganisms grow while harmful pathogens die,
through competition for nutrients.
** Due to the effectiveness of the Green Cone Composter in controlling
decomposition process, and the inaccessibility to animals, birds and
humans, the overall health, safety and environmental risk of using the
Green Cone Composter is virtually nonexistent. However, we still recommend
locating your Green Cone Composter away from any food gardening area if
you choose to add animal waste to your Green Cone Composter. Make sure not
to include any litter (clay or other). If you are digesting animal waste
products, we also recommend locating the Green Cone Composter at least
100' from any well/water source.
Your Green Cone Composter needs very little maintenance.
However, it is important to ensure that the top of the basket and the
bottom lip of the outer Green Cone Composter are below ground level and
always fully covered with soil.
In a well operating Green Cone Composter, very little waste residue will
be produced. Should the residue build up to ground level and not decrease,
the cones can be removed to access the basket. The harmless residue can
then be buried into any suitable area of the ground.
- Choose a sunny spot in the garden -- the sunnier the better.
- The Green Cone Composter converts food waste primarily into
water and carbon dioxide. The water produced must be able to
drain freely away, otherwise the Green Cone Composter will
become anaerobic (without oxygen) and will cease to work. It is
therefore crucial to install your Green Cone Composter in an
area of good drainage. Under no circumstances should the base of
the basket be below the water table or where water gathers. If
you believe your soil drains well, dig a hole 32" wide and 24"
deep. Then pour a bucket of water into the hole. If the water
disappears in less than 5 minutes, you have good drainage. If
the water remains for more than 15 minutes, you have poor
drainage or if you live in an area of heavy clay or chalk where
drainage isn't as good, you will need to dig a hole 36" wide and
- Mix some of the soil from the hole with gravel and/or compost
for backfilling later. In areas of heavy clay or chalk, include
gravel, small stones, small pieces of broken terracotta pots, or
small pieces of broken bricks in the mixture to aid drainage.
- Place the mixture in the base of the hole so that the base of
the basket is 1" below ground level at the base of the hole.
- Place the assembled Green Cone Composter in the hole. Ensure
the top of the black basket and the bottom lip of the green
outer cone are below ground level.
- Backfill the gap around the Green Cone Composter with the
mixture until the bottom lip of the Green Cone Composter is
- Your Green Cone Composter is now ready for years of productive
use. Be sure to periodically check your soil level, which may
drop with heavy rain. To check, make sure that the bottom lip of
the green outer cone is fully covered, adding backfill as
Frequently Asked Questions:
Is the Green Cone Composter
System easy to use?
Yes, very. In your kitchen, fill the Green Cone Composter caddy or other
transport bucket with all your organic kitchen waste. When convenient,
empty the caddy into the Green Cone Composter in your garden.
Can I use chemical activators as
No. Chemicals can kill or disrupt the bacteria breaking down the food
waste. The only activator that is recommended for use is the all-natural
Green Cone Composter Compost Boost Compost Accelerator.
Where should I install the Green
The ideal location for the Green Cone Composter is a sunny, close-at-hand
spot like a flowerbed or vegetable garden (see notes about placement below
if you are adding animal waste to your Green Cone Composter). For best
results, avoid cold, dark, wet places in the yard.
Can my Green Cone Composter stop
It's easy to have a well-functioning Green Cone Composter. However, some
problems may occur if:
- The Green Cone Composter is installed in a very dark, shady area.
- The surrounding soil isn't well-drained, or if the soil contains heavy
clay or chalk.
- The black basket is below the water table or in an area where water
In these circumstances, the Green Cone Composter's digestion process
could turn anaerobic (without oxygen). You can tell that by examining the
food waste. If it looks wet and slimy, the Green Cone Composter should be
In periods of very cold weather the digestion process may slow down due
to lack of natural bacteria. This would be evident by the level of waste
in the basket not decreasing. Under these circumstances, the addition of
the natural Green Cone Composter Compost Boost Compost Accelerator should
restore the bacteria population and restart the digestion process.
Can I use my Green Cone Composter to
dispose of animal excrement?
Yes, in moderation. When it is time to empty the Cone, take care to wear
gloves and make sure you wash your hands. DIGESTED ANIMAL WASTE IS NOT
INTENDED TO BE USED IN YOUR EDIBLE GARDEN
Can I put garden waste in my Green
It is better not to. A traditional compost bin or heap is better at
handling garden waste such as grass cuttings.
How much food waste can I put in my
Green Cone Composter?
Provided your Green Cone Composter has been correctly installed, 1-1/2 to
2 pounds (roughly one gallon) of food waste can be placed in your Green
Cone Composter every day. This amount is typical of that produced by a
family of four. The precise quantity of waste digested by your Green Cone
Composter each day will depend upon the ambient temperature, the
population of bacteria and the mix of food waste you produce.
Why is there a bar across the top of
the Green Cone Composter?
The bar across the mouth of the Green Cone Composter provides some
rigidity in storage and transit. Its purpose is to prevent small children
climbing into the Green Cone Composter. However, turning the twist-lock on
the lid and serves the same purpose. The bar may safely be removed
(carefully using a hacksaw) to allow large scraps to be put more easily
into the Green Cone Composter. However, if you alter (i.e. remove the
safety bar) the Green Cone Composter in any way, even if it is brand new
and unused, it is not returnable under any circumstances.
Will the Green Cone Composter
The Green Cone Composter is a sealed unit and when properly installed,
emits no odors. It does not, therefore, attract flies. However, the eggs
of fruit flies are already in the skins of many fruits and can hatch out
in the Green Cone Composter. Similarly, if food or food waste is not kept
covered prior to going into the Green Cone Composter, its possible for a
housefly to lay eggs before the food reaches the Green Cone Composter.
These would also produce maggots and flies in the Green Cone Composter.
Good housekeeping is therefore important. Some people will freeze food
scraps before depositing them into the Green Cone Composter. This may
significantly reduce the possibility of flies--should they occur at all.
Will the Green Cone Composter
If correctly installed, your Green Cone Composter will not attract
critters. By ensuring that the top of the black basket and the bottom lip
of the green outer cone are below ground level, you will harmlessly
filter out any odors into the surrounding soil. It is also
important not to spill food near the Green Cone Composter.
If you suffer from rats in your yard, you could be unlucky with a rat
running across the Green Cone Composter. If you think there is a chance of
this happening you should put chicken wire around the black basket to
prevent a rat or other critter from gnawing its way through into the
Does the Green Cone Composter
Not really. Because of the amount of oxygen inside your Green Cone
Composter, the decomposing food will produce very little methane.
Do I have to turn or mix the
contents in my Green Cone Composter?
No, just put all your food waste into the Cone and forget it. Your Green
Cone Composter does all the hard work for you.
When and how often should I empty my
Green Cone Composter?
In a well operating Green Cone Composter, the waste residue will only need
to be removed every few years and certainly no more than once a year. It
requires emptying when the residue builds up to about 4" below ground
level and shows no signs of reducing.
Will my Green Cone Composter work
all year round?
Yes. Your Green Cone Composter works 365 days a year. The level of food
waste may rise during winter but should drop down when the weather gets
warmer. If decomposition slows during very cold periods, use the natural
Green Cone Composter Compost Boost Compost Accelerator.
