ANAEROBIC DIGESTION AND BIOGAS
TECHNOLOGY

A contribution to Environmental Protection and
the Conservation of Natural Resources

1. Fundamentals

The main principle of anaerobic digestion technology is to feed biomass, including in particular waste materials and by-products (agricultural wastes; kitchen scraps; feaces; organic wastes) into a closed container, the biodigester. In the absence of oxygen, this digestion material is converted into high-value fertiliser humus, and pathogenic germs are eliminated at the same time. The bacteria involved in this process produce a biogas mixture composed of 35% carbon dioxide and 65% methane. Biogas can be used as an alternative source of energy in many ways. The whole system works without any external energy input.

2. Areas of use

For a very long time, biogas units used to be regarded only as sources of energy for cooking, baking, and lighting.

However, due to the fact that it is capable of converting waste material into......
