Greece - Northern Greece

The Greek agriculture has two main challenges: the very high costs of energy and chemical fertilizers, and pollution of water and soil due to intensive and unreasonable use of chemical fertilizers. Also, soils are subject to a strong mineralization of organic matter and a degradation of their physico-chemical and microbiological properties. The aim of this LL is to optimise the double recovery of the production of biogas and materials to be used as SI from abundant FPR.

Key Exploitable Results (KER):

Partners:

3 Waste4Soil partners are directly involved in the Greek Living-Lab: CERTH, CLUBE and DIADYMA. CERTH will lead the Greek LL and will be responsible for running the separation technologies and analyses, as well as bringing in food processing industries, biogas plants, and biofertiliser companies to collaborate with the LL, while CLUBE cluster will be responsible for the formulation and distribution of end products to farmers and other members of the cluster. 

Subsequent processing of the digestate will be promoted and several techniques including the electrochemical SED nutrient recovery processing will be further employed into a diverse number of digestates with FPR origin used in Northern Greece biogas plants participating in the LL.

CLUBE will work on triple helix aspects of the living lab. DIADYMA will support transportation and handling of FPR. Subsequent processing of the digestate will be promoted and several techniques including the electrochemical SED nutrient recovery processing will be further employed into a diverse number of digestates with FPR origin used in Northern Greece biogas plants participating in the LL.
