Application of the ordinance
The operation is subject to the rules of the German hazardous-incident ordinance. The notification under § 7 (1) was submitted to the competent authority as part of the permit procedure.
Activities on site
The plant produces biogas as part of the regional value chain from the following inputs:
- Cattle manure / pressed cattle slurry
- Cereal grains
- Poultry manure
- Horse manure
- Maize silage
- Whole-crop cereal silage (GPS)
Operations on site:
- Storage of biomass as farmyard manures or silages
- Removal of biomass and feed-in to the fermentation process
- Pumping between the feed system, fermenter and digestate storage
- Separation of the digestate and interim storage
- Removal of the fermented digestate (separated or liquid) for transport and/or for application as farmyard manure on agricultural land in line with the German fertiliser ordinance
- Production of biogas in a gas-tight fermentation system
- Interim storage of the biogas in the gas-storage system
- Power generation from biogas in CHP units
- Use of waste heat to warm the fermenter
- Use of waste heat for the estate's own district-heating loop
Relevant hazardous substances
8,233 m³ of biogas, corresponding at a density of 1.31 kg/m³ to 10,757 kg (Annex I no. 1.2.2 of the 12th BImSchV — "flammable gases", threshold 10,000 kg).
Population warning and conduct in case of an incident
Biogas is produced and stored in a closed plant that is continuously monitored by measurement, steering and control technology, and is burned via combustion devices (CHP units and flare). A release is therefore very unlikely. Should one nevertheless occur, affected residents are identified and informed in a targeted manner with appropriate means.
