Leeuwarden, Netherlands – January 8, 2024
The GR4SS project, an initiative at the Energy Campus Leeuwarden, announces a series of pilot tests involving the digestion of a mixture of verge grass and straw pellets. These tests are crucial to assess the efficiency and technical details of the digestion process and further explore the potential of this technology for green energy production.

The primary goal is to determine the stability of the digestate, the residual product after digestion, both with and without an additional composting step. This will provide essential information on process optimization and the quality of the end product.
Another important aspect of the pilot tests is the determination of the distribution of salts and heavy metals between the thick and thin fractions of the digestate. Finally, during these tests, biogas yield will be measured accurately.

These pilot tests represent a significant step in achieving the ambitious goals of the GR4SS project, namely the production of renewable energy from local and sustainable sources, while simultaneously making a positive contribution to the environment.

About the GR4SS project
The GR4SS project, under development at the Energy Campus in Leeuwarden, is an innovative initiative focused on converting verge grass into green energy. Through advanced digestion technologies, the project aims to make a significant contribution to renewable energy production while also having a positive impact on the environment and the local economy.
