The latest episode of ScienceMe features Stergios Vakalis, Assistant Professor at the National Technical University of Athens (NTUA) and the University of the Aegean. During the episode, he discusses the role of energy and environmental technologies in addressing current sustainability challenges and highlights BioFairNet’s work on hydrothermal carbonisation.
Showcasing BioFairNet’s hydrothermal carbonisation pilot
Among the topics discussed was BioFairNet’s hydrothermal carbonisation (HTC) pilot in Lesvos, Greece, which explores innovative ways to transform biomass and organic residues into valuable resources. The pilot investigates how wet biomass streams can be processed and valorised, contributing to more circular and resource-efficient systems.
Within BioFairNet, this work contributes to the development of sustainable bio-based value chains while generating knowledge and data that support wider project activities for example the Information Green Factory.

Connecting research, energy and circular economy
The conversation also explored broader topics related to energy transition, environmental technologies and the challenges of developing solutions that can respond to both industrial and societal needs.
Particular attention was given to the opportunities created by circular approaches to resource management and waste valorisation. These perspectives are closely connected to BioFairNet’s objective of supporting the transition towards fair and circular bioeconomy models through innovation, collaboration and practical implementation.

Bringing BioFairNet to wider audiences
The podcast offered an opportunity to present BioFairNet to Greek audiences beyond the project community and showcase how research activities are being translated into practical solutions. Through pilot activities such as hydrothermal carbonisation, BioFairNet demonstrates how innovation can contribute to reducing environmental pressures while creating new opportunities for resource recovery and circular value creation.
By sharing the science behind the HTC pilot with a wider audience, the episode highlights the importance of connecting research, innovation and real-world applications in the transition towards a more sustainable future.
