Diagramme der Biogasproduktion

Die Biogasproduktion wurde von 14 internationalen Arbeitsgruppen durchgeführt. Das durchschnittliche Ergebnis, Auswertung und Diskussion der 14 Arbeitsgruppen werden im Diagramm unten dargestellt:

Auswertung und Diskussion

Das Diagramm zeigt das durchschnittlich Ergebnis der Biogasproduktion, mit Mais als Substrat während den 5 Stunden der Fermentation.

The blue glucose curve starts at 10 g/l, since we added 10 g glucose per litre of substrate at the beginning. The glucose concentration is decreasing continuously because it’s metabolised by the microorganisms as the easiest energy source.

Die blaue Glukosekurve beginnt bei 10 g / l, da wir 10 g Glucose pro Liter Substrat, am Anfang, dazugeben. Die Glucosekonzentration nimmt kontinuierlich ab, weil es durch Mikroorganismen abgebaut wird.

Die grüne Kurve zeigt das gemessene Biogas in Liter.

Die rote Kurve zeigt die Gasqualität von Methan(%) im produzierten Biogas.

Es beginnt immer bei 0, da die Organismen während der Befüllung des Behälters aeroben Bedingungen hatten.

Die Qualität hängt auch von anderen Parametern, wie Temperatur, die bei 50 ° C optimal ist. Der optimale pH-Wert ist bei 7, 1.

Die Ergebnisse der 14 Arbeitsgruppen sind in den folgenden Diagramme dargestellt:

5. Teacher-mentor meeting February 2017 in Miskolc
Programme:
Presentations about several energy soures, their advantages and disadvantages which should help the mentors in the following workshop in Brno as a working basis for the discussion about a future energy mix in Europe.

6. Energy workshop with ethical discussion April 2017 in Brno
Programme:
We discussed the advantages and disadvantages of the different energy sources. Therefore we heard  presentations about those energy sources from our mentors. In small international groups we evaluated the possible options of the pros and cons, ethical consequences and ethical values of the different energy sources. The mentors guided us through a rotating system of different work stations. All international groups made the decisions for their own energy mix and created a pie chart to explain their energy mix to the audience. An average pie chart was made out of all the pie charts from every group. Finally we discussed this average pie chart and compared it with the current energy mix from Europe. (see results)
