Aerobic process

- reduced greenhouse gas emissions

Earthmaker’s unique aerobic process supports new waste material on shelves above the ground. Heat absorbed through the black plastic, and generated naturally by the decomposition process, draws air up through the material. Aeration is increased when material loosens as it spills from shelf to shelf.

(Single bin composters are simply covers over a pile of waste on the ground. The anaerobic decomposition creates methane, leachate and rotten smells. Single bins only work if the material is regularly lifted and turned, but this mixes new waste material with old.)

(Compost tumblers use a batch-by-batch process.Two may be needed so one can be left to mature while the other takes the new kitchen and garden waste.)

Earthmakers take new waste at any time. The oldest waste is available at the bottom when needed.

Easy to use

- 3 stage system

Earthmaker’s three–bin composting process is stacked vertically so gravity does the hard work!

Earthmaker’s continuous cycle keeps new material away from old. Add food and garden waste at any time. Remove mature much or compost when convenient.

Earthmaker’s push–pull–tool makes it easy to mix and move material without heavy lifting and turning.

How it works

Top Chamber Mixing

As organic waste from the kitchen and the garden builds up in the top chamber, microbial action begins the decomposition process. Fungi and bacteria generate heat. Radiant energy from the sun, absorbed through the black plastic, also helps.

Middle Chamber Digesting

When material is moved down to the cooler climate of the middle chamber, biological mulching continues with invertebrates assisting microorganisms. Worms which may appear here or in the top chamber, will have hatched from eggs in the grass cuttings and leaves.

Bottom chamber Maturing and Storing

As material reaches the ground, excess water drains and the conversion of mulch into compost begins. If left long enough it will become sweet-smelling and ‘friable’, but it can be added to your garden at any stage as mulch or compost.
