Water scarcity, energy independence and the role of hybrid renewable energy systems
(Corresponding) Bertsiou M., Baltas E.
Topic:
Renewable energy sources
Water scarcity problems and the need for reduced consumption of fossil fuels lead to the transition to renewable energy sources (RES). The proper management of RES is the key issue, especially in small not interconnected islands. In this research work a Hybrid Renewable Energy System (HRES) on a...Read more

Investigating the Performance of Anaerobic Co-Digestion of Primary Sludge and Acid Whey Using a Twin Pilot Scale System
(Corresponding) Gkoumas F., Tzivelou E., Gravanis Z., Mamais D., Malamis S., Noutsopoulos C.
Topic:
Waste-to-energy
Anaerobic Digestion (AD) has proven to be an effective method for transforming organic waste into biogas, a renewable energy source that can play a crucial role in reducing our dependence on finite fossil fuels. Despite its widespread use, mono-digestion, where a single substrate is utilized, is...Read more
Comparative evaluation between new construction and refurbishment of existing buildings with the exploitation of their Embodied Energy and Carbon Footprint
(Corresponding) KONDILI E., KALDELLIS I., ENTMONS A., PETROVITS N.
Topic:
Circular economy and industrial symbiosis
On a global basis, buildings consume about 60% of raw materials per weight and almost 1/3 of the global energy consumption quantities. For many years the most important issue determining the sustainability of a building has been the energy consumed during its operation. However, recently a trend...Read more
