Aerobic process

- reduced greenhouse gas emissions

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

(Single bin composters are no more than covers for a pile of waste on the ground. When left, this waste will decompose anaerobically creating 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, slowing the process.)

Easy to use

- 3 stage system

Earthmaker uses traditional three–bin composting but stacked vertically so gravity does the hard work!
Earthmaker’s continuous cycle keeps new material away from older material. Food and garden waste can be added at any time. Mature much or compost can be removed when convenient.

The Earthmaker push–pull–tool makes it easy to mix and move material through the process without straining your back with 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.
