24 hour food waste recycling machines

Loading the indoor compost machine

Our aim with this article is to inform and to explain how and why the compost machine chamber will fill up gradually, and not instantaneously, like many people believe.

A large part of the mass of most organisms is simply water. In humans, it ranges from 20% in bones to 85% in brain cells. About 70% of our total body weight is water and in plants and certain animals like, jellyfish it is as high as 90%. The high water content and cellulose structures in plants causes its bulky appearance. This bulkiness in our food waste will reduce as soon as the composting process starts.

During composting, the microorganisms consume oxygen from the surrounding atmosphere, while feeding on organic matter. Active composting generates a considerable amount of heat, and large quantities of carbon dioxide and water vapour are released. The carbon dioxide and water losses can amount to half the weight of the initial organic materials, so composting reduces both the volume and mass of the raw materials while transforming them into a beneficial humus-like material.

The above, explains why the chamber will fill up slowly and the amount of compost generated from the household W2D machine will be less than 60 to 100dm3 per year. In simpler terms, it will be equal to 30 to 50 × 2 litre soft drink containers.
