Project Attero


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
