Soil formation
Soil formationBack to nature
At the Langes Feld and Fischamend sites, compost is produced according to a specific formula for use in landscaping and as a water retention layer.
The composting process takes place in an open windrow system using biogenic waste such as wood, green waste or municipal sewage sludge. Fine mineral fractions and wood ash serve as additional components.
The hygienising heat composting process corresponds to an aerobic, exothermic, microbiological and biochemical conversion process. The process is comparable to the commonly known composting. Whilst in composting the end product is usually equivalent to an organic fertiliser, heat composting produces a pre-planned end product whose quality as soil is guaranteed.
Once the microbiological decomposition or conversion activity has subsided, the so-called ‘raw humus stage’ begins. The ‘raw humus’ produced is mixed with further additives in accordance with the latest results of the process control (PK3), and the soil formation process is completed. The end product corresponds to fertile topsoil.
The materials used for vermicomposting are subjected to strict quality control at both the input and output stages to ensure a consistent process. The progress of the thermal composting process is monitored through continuous gas and temperature measurements, as well as three process control analyses.
