Greenstep® commissioning:  August 2016

Organic kitchen and garden wastes are converted into biogas in four thermophilic (53°C) anaerobic digesters. Attero has chosen to integrate the Greenstep® technology into their process to improve degradation resulting in shorter residence time and increasing biogas production.

  • Feedstock: 90% Organic kitchen and garden waste, 10% co-products (FOG)
  • Green electricity production: 12.000.000 kWh per year
  • Equivalent electrity consumption of approx. 4.000 Dutch households
  • Gas production: 17.000 m3/day
  • Electric power production capacity: 1.600 kWe
  • Digestion process temperature: 53 degrees Celcius

  • Feedstock: 50% pig manure, 10% maize silage, 20% nature grass, 20% co-products (FOG)
  • Green electricity production: 13.600.000 kWh per year
  • Equivalent electrity consumption of approx. 4.533 Dutch households
  • Gas production: 20.000 m3/day
  • Electric power production capacity: 1.700 kWe
  • Digestion process temperature: 40 degrees Celcius

Groot Zevert

Beltrum

Greenstep® commissioning:  May 2018

Groot Zevert unit produced its own electricity and heat thanks to a mesophilic (38°C) digestion process. This represents 20% of the total biogas production. The other 80% are supplied to the next-door dairy cooperative via a 6km pipe. Doing so  a 100% energetic conversion of the biogas to heat is realized. This is  a  great example of methanation integration in the local economy !

  • Feedstock: 80% manure and 20% co product (food waste  and agricultural)
  • Green electricity production: 4.000.000 kWh per year
  • Equivalent electrity consumption of approx. 1350 Dutch households
  • Gas production: 8 millions Nm3/year
  • Electric power production capacity: 500 kWe
  • Digestion process temperature: 53 degrees Celcius
