Biogas plant

Power generation thanks to the utilization of energy from production waste

In order to prevent greenhouse gas emissions before they are created we produce natural gas in our biogas plant from our production waste such as e.g. potato peel. However there are also other materials such as the filtered starch from our potatoes which help us to generate sufficient power for approx. 400 households.

We then use this power for the production of our potato specialities and also feed it into our local electricity grid.

 

How does a biogas actually work?

In a biogas plant an anaerobic process takes place; that is a decomposition of biomass such as. potato peel which is carried out without oxygen. Through the addition of micro-organisms a fermentation process takes place in which biogas is formed. We use the biogas thus obtained to generate electricity in a block type thermal power station.

Thus we are not only able to avoid CO2 but also contribute to the support of alternative forms of energy.

Effluent treatment

Water volumes and CO2 are reduced through effluent treatment

For the production of our potato specialities we need water e.g. for blanching our potatoes. In our own plant for the treatment of effluent we are able to recycle the large volumes of water used in our production process. Thus at the same time we are able to reduce our emissions of CO2.

It is our belief that above all one must invest in the manufacture of water-saving and energy-efficient plants in order to make a lasting contribution to climate protection.

Heat recovery

Systematic utilization of waste heat

A high usage of energy is necessary for the production of frozen potato specialities e.g. for heating the water used in production. Moreover a great deal of heat is accrues from the various production processes such as frying, steam peeling or blanching. Through the use of a recycling plant we are able to reuse this waste heat in our own production again. Thus unnecessary CO2 emissions are prevented.

 

Saving of fossil fuels

Using our recycled waste heat approx. 70,000 litres of water for the production process can be heated up.

Steigerung der Nutzungseffizienz der Kälteanlage

Das Projekt hat den Zweck, die Wärmenutzung aus der Kälteanlage erheblich zu steigern. Dafür ist eine Optimierung und Flexibilisierung des Wärmemanagements erforderlich, damit neue Verbrauchsmöglichkeiten erschlossen werden. Damit eine ganzjährige Nutzung der Wärme für Produktionsprozesse und Heizzwecke möglich ist, wird ein Wärmeniveau von 85°C benötigt.

 

Diese wird über einen großen Pufferspeicher realisiert, der durch Ergänzungswärme aus einer KWK – Anlage auf das erforderliche hohe Temperaturniveau von 85°C angehoben wird. Durch die Erweiterung der Wärmenutzungsmöglichkeiten kann Erdgas ersetzt und langfristig eine weitere CO2 Einsparung in der Größenordnung von ca. 360 to/a realisiert werden. Die geplante Maßnahme besteht aus Pufferspeicher für 70.000 l, ergänzende HLS Technik, ca. 300 m Fernwärmeleitung sowie der erforderlichen Elektro- und Steuerungstechnik.
