Green Cone


Product comparison


The more care you take installing your Green Cone the greater its efficiency.

The Green Cone converts food waste primarily into water and carbon dioxide. The water produced must be able to drain freely away otherwise the Green Cone will become anaerobic (without oxygen) and cease to work. It is therefore vital to install your Green Cone in an area of good drainage - or create good drainage by putting gravel (or small stones,small pieces of broken terracotta pots, small pieces of broken bricks) under the basket.

Under no circumstances must the base of the basket be below the water table or where water gathers.

Choose a location

Choose a sunny spot in the garden.

Avoid the Shade

Avoid installing your Cone in the shade as the lack of sun will affect its efficiency.

Prepare the Ground

If your soil drains well dig a hole 80cm (32') wide and 60cm (24') deep.

When you have dug the hole, pour a bucket of water into it, if the water disappears within a few minutes you have good drainage. If the water remains for more than 15 minutes you have poor drainage and will need to enlarge the hole.

Alternative Ground Preparation

If you live in an area of heavy clay or chalk dig the hole 90cm (36') wide and 70cm (28') deep.

If you cannot dig deeper due to heavy clay or cannot obtain good drainage, mix some of the soil from the hole and/or compost with gravel, stones, broken bricks or broken pots to aid drainage.

Alternatively make a feature of the cone in your garden by planting your cone in a raised bed made of wood (as per photo) or stone/bricks.

Install the Cone

Place the assembled Green Cone in the hole. Ensure the top of the black basket and the bottom lip of the outer cone are below ground level.

Refill the Hole

Backfill the gap around the cone with the mixture of the soil, compost, stones etc you saved when digging the hole until the bottom lip of the Green Cone is fully covered.


Your Green Cone is now installed!

Please Note

The soil level will drop after installation and with heavy rain. Check periodically ensuring that the bottom lip of the green outer cone is fully covered.
