Food waste should be dropped into the Cone directly, not in bags of any kind, even compostable ones. 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. Each Green Cone comes with a waste caddy for collecting food scraps. When the caddy is full, you take it outside and add the scraps to the Green Cone, then close the cone’s lid. The Green Cone is a unique and environmentally-friendly solution for disposing of household food waste. The unit accepts all cooked and uncooked food waste including vegetable scraps, meat, fish, bones, dairy products and other organic material. Nature does the rest, reducing the Green Cone's contents to water and carbon dioxide. Over 90% of the waste material in your Green Cone will be absorbed as water by the soil. Designed for a sunny spot in a well drained garden, the Green Cone is suitable for an average household of four people. The Green Cone is a solar-powered food waste digester that efficiently disposes of all food waste - including cooked food, meat, fish (even bones) and dairy - with no turning or stirring required. Because the Green Cone has a seal to prevent smells from escaping, it does not attract flies. But if there are already eggs inside fruit peels — with oranges and bananas being prime locations for fruit flies to lay eggs — they may hatch inside the cone. Additionally, leaving food uncovered on the counter or table before putting it in the cone gives flies a chance to lay eggs in it.

A compost system produces compost — fertile, nutrient-rich soil — as a byproduct of the decomposition process. It requires the addition of carbon material like straw, paper, or leaves, and you may have to turn the material to help it break down. 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. The Green Cone uses solar heating in its double-walled chamber to speed up the aerobic decomposition process in the underground digestion basket.Made in the UK from 100% recycled plastic, the Green Cone has an expected lifespan of 10 years or more. The Green Cone comes with accelerator powder and a shaker jar. Where the Green Cone is situated in a position that does not enjoy full sun or during long periods of cold weather, the digestion process may benefit from the application of accelerator powder. Simply shake a small amount of powder into your compost pail before emptying food waste into the Green Cone. The regular addition of a little accelerator powder (a mixture of natural bacteria on a cereal base) is necessary to boost the digestion process. Embedding the Cone in soil means that bacterial digestion occurs below ground level so any odours are absorbed by the soil.

Invented in 1988, the Green Cone is a double-walled, solar-powered biodigester that sits partially buried in the ground. Through the process of aerobic decomposition, it helps people break down their food and pet waste right at home — all without any odors. To use it, you just open the lid, add waste, sprinkle in the occasional bacteria, and close the lid again. The underground portion of the cone allows insects and microorganisms to aid in decomposition.

Green Cones break down waste aerobically. As bacteria carry out digestion, they return the carbon to the soil where it becomes part of the carbon cycle. The process does not emit gases into the atmosphere. Because these solar cones have a double-walled structure, they trap heat that speeds up the decomposition process. Green Cones are not bear proof. If you live in bear country, you may need to install the cone in a protected area, such as surrounded by an electric fence. Another deterrent is to put cayenne pepper on the lid after each use. Additionally, it’s a good idea to wait until bacteria become well established in the cone before adding animal attractants like meat, fruit, and other strongly scented foods. A small amount of waste residue is produced which can be emptied every few years and dug into garden soil. With most people discarding a significant portion of their food, organic waste has become a huge issue worldwide. Cat and dog poop have also become an increasing problem as pet populations increase.
