The Green Cone is a solar-powered food waste digester that 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 uses solar heating 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.
