Structure

1. producing biogas

2. using biogas

3. the biogas plant in Schmiden

Producing biogas

• Biomass (e.g. maize silage) is taken by local fields and saved in a storage

Producing biogas

• One time a day, new biomass/silage is putted into the screw charger from were it is transported into the fermenter

Producing biogas

• The biomass/silage is permanently mixed up in the fermenter

• Biogas is produced because of the heating and mixing process of the biomass/silage in the fermenter

Producing biogas

• The “old” biomass/silage is transported into a second fermenter/ reservoir:– Biogas is built– Biomass is saved to be used again by agriculture

fermenter second fermenter/reservoir

Using biogasFirst biogas must be filtered to methan

By burning down the biogas in a block heating station heat and electricity is produced

The heat partly is transported in the fermenter and partly to near buildings

The electricity is putted into the electric circuit

The biogasplant in Schmiden

• The biogas of this plant produces …… heat for the own fermentation process… heat for two school centres (in Schmiden and

Oeffingen)... heat for some gyms and two festival halls… electricity for the electric circuit

• This is possible because of 3 new block heating stations
