About the project

Arable crops account for a large proportion of the identified potential for increased biogas production in Sweden. This project can contribute to a better understanding of how crops can be used with lower costs.

The project has investigated if the substrate cost can be reduced by organizing the substrate supply in a new way, using both fresh and ensiled (stored) crops. The project has been conducted in cooperation with the Swedish biogas producer Gasum AB (formerly Swedish Biogas International, SBI) and contains two case studies based on the Gasum AB facilities in Örebro and Jordberga that has analyzed how fresh and stored crops should best be combined to minimize the cost. The analysis has been done by cost calculations and an improved optimization model for substrate supply during different times of the year.
