C/N-ratio
Definition:

The C/N-ratio is defined as the relation between carbon and nitrogen. The substrates are mixed together as long as an optimum ratio between 25:1 and 35:1 is reached. If it is outside of the optimum conditions, higher emissions, slower starting process, loss of nutrients, etc are the consequences.

Chemical oxygen demand (COD)
Definition:

The chemical oxygen demand (COD) is defined as a sum-parameter for the contamination of the sewage with organic substances. The COD shows the amount of oxygen [mg/l], which is necessary for the chemical oxidation of the organic materials in the sewage.

CLO
Definition:

Under compliance with certain conditions, in some contries it is allowed to use the fine fraction of the stabilised waste (< 15 mm) as landfill greening as far as the amount of foreign particles does not exceed a maximum limit value. This fraction is named CLO („Compost Like Output“).

Composting
Definition:

Composting is the biological process of the nutrient cycle, where bacteria and fungi (micro-organisms) degrade biologically degradable organic material under the impact of oxygen (aerobic). Beside the formation of carbon dioxide (CO2) also water-soluable minerals like nitrate, ammonium, phosphate, kalium and magnesium are released, which have a fertiliser effect. A part of these substances are saved in the form of Humus.

For the composting process the following material parameters are important:

Water content 40-60 %
Material density max. 650 kg/m³
C/N ratio 30:1
