Abstract
At the 25th anniversary of the “Report on Our Common Future” - an important point in turning the world towards a more sustainable future the 7th SDEWES (Sustainable Development of Energy, Water and Environment Systems) Conference was aimed at discussing sustainable development of energy, water and environment systems and providing adequate scientific support to the emerging international, European, regional and national challenges. Held in Ohrid, the pearl of Macedonia and a UNESCO world heritage site, this was the first of SDEWES conferences organised outside Dubrovnik, and welcomed more than 200 scientists from around the world – from 45 countries to present research progress and to discuss the state of the art, the future directions and priorities in the various areas of sustainable development. This Special Issue (SI) attempts establishing a novel collaboration of the SDEWES conference with Chemical Engineering Transactions (CET) and builds upon the experience and common values of the conference organisers and CET. The main topics discussed in the articles of this special issue include strategic considerations on energy and water supply and security, process energy efficiency and intensification, use of renewables, pollution reduction and waste management.
