Green Cone 80 Litre Food Waste Digester

Made in the UK

The Green Cone efficiently disposes of all food waste - including cooked food, meat, fish and dairy - with no turning or stirring required.

Dug into a hole in well-draining soil in a sunny position, the Cone reduces more than 90% of its contents to nutrient-rich water, which drains out of its underground basket and feeds surrounding soil. 

Embedding the Cone in soil means that bacterial digestion occurs below ground level so any odours are absorbed by the soil.

The Green Cone traps heat in its double-walled chamber to speed up the aerobic decomposition process in the underground digestion basket.  

The basket should be placed in a hole about 70cm wide/54cm deep in free-draining soil (not clay or chalk) in a sunny spot in the garden.

Food waste (no garden waste) should be dropped into the Cone directly, not in bags. Waste lands in the underground basket, where micro-organisms and worms enter and begin to break it down.

The upper part of the Cone above ground remains empty: the inner and outer cones create a heat trap of circulating air that facilitates the growth of beneficial micro-organisms and promotes the aerobic digestion process.

A small amount of waste residue is produced which can be emptied every few years and dug into garden soil. The Cone does not produce compost.

A well-positioned Cone can digest the food waste produced by the average household. 

Regular additions of accelerator powder (a mixture of natural bacteria on a cereal base), especially in winter, add beneficial micro-organisms to boost the breakdown process.

Made in the UK from 100% recycled plastic, the Green Cone is fully guaranteed for five years and has an expected lifespan of 10 years or more. The Cone comes with a free kitchen caddy and a starter pack of accelerator powder.

Designed in Canada to solve the problem of bears knocking bins over in search of food, the Green Cone is a best-seller in Canada, the US and Australia.

Frequently asked questions

Yes, we offer free standard shipping for orders within the UK. Additional charges may apply for deliveries to remote areas or international locations.

You can dispose of up to one kilogram of waste per day in a well-positioned and fully working Green Cone. As long as the unit has a healthy population of bacteria, a consistent ambient temperature and a balanced ‘diet’, it can dispose of the food waste created by the average family of four per day.

No, grass cuttings and garden waste will stop the Cone from working properly. For garden waste, you should consider the Green Johanna hot composter.

Yes, in moderation, if you are not using the residue on a vegetable patch and the Green Cone is not sited close to water sources. Pet excrement must be added to the Cone directly, never in a bag. Bags of any sort, even compostable or biodegradable, will prevent the Cone from working properly. Avoid adding cat litter as this may contain antibacterial agents and its quantity could quickly overwhelm the Cone.

No. The Green Cone is designed to break down waste naturally without assistance.

Yes, although it may slow down a little on darker, colder days. But a little accelerator powder will keep it working as usual no matter what the weather.

No. Any artificial additives will affect the way the Cone’s natural bacteria works to break down the food waste.

With a well-maintained Cone you may need to empty and clean it once every few years. Very little waste residue will be produced. Should the residue build up to approaching ground level and show no signs of reducing, the Cone can be removed to access the basket and the residue can be dug into any suitable area of ground.

Simply hand wash it in warm soapy water. Do not put in the dishwasher.

The Green Cone is a sealed unit and when properly installed, with the top of the black basket and bottom lip of the green outer cone below ground level and the lid shut securely, emits no smell; any smells are filtered out by the surrounding soil. This means there is no obvious attraction for flies and vermin. However, the eggs of fruit flies are already in the skins of many fruits and might hatch out in the Cone. Should this happen, a small squirt of organic fly spray will resolve the issue. It is important that the caddy is always kept well covered in the kitchen to prevent house flies laying eggs in the food waste, which would then be transferred to the Cone, putting flies into the system. Again, a squirt of organic fly spray will clear up the issue without hindering the eco-system in the unit.

Obviously, it is important not to spill food near the Green Cone.

Advice given in the handbook should be followed for the Green Cone to continue working properly:

Position the Cone in as sunny an area as possible, not a dark, shady area as it is solar powered.
The surrounding soil must be well drained and not heavy clay or chalk.
The black underground basket must not be below the water table or in an area where water gathers.
Accelerator powder should be added to the Cone so that there is enough natural bacteria to keep digesting the waste. This is particularly important in cold weather. If the level of waste in the basket is not decreasing, add accelerator powder, as directed in the handbook.
If the instructions are not followed, the digestion process could turn anaerobic (without oxygen) and the food waste may appear wet and slimy. The solution in this case is to reinstall the Cone in accordance with the instructions.
