Interview with N. Lygeros by N. Chazaridis. ALPHA Radio 88.6, Kavala, 1 March 2017
Following years of campaigning to promote the use of Greek zeolite, an official licence has been granted to operate the quarry for this industrial mineral, on a public plot of 83.4273 stremmata, at Kokkalo Petrotwn in the municipality of Orestiada, Evros, to Olympus S.A. The decision was taken by the Ministry of Environment and Energy…

South Africa has large coal reserves. It mainly burns coal to produce electricity at 13 existing coal-burning power plants, situated mainly in Mpumalanga, a province in the country’s east. In South Africa, coal power generation results in at least 36 million tonnes of solid waste residue called fly ash being produced annually. That’s the equivalent of six dumps each…
Mostafa Ragab Abd El Wahab, Moaa Korany Seliem, Essam Abd El Rahman Mohamed, Ali Quarny seliem, Mohamed Gad Shahien Abstract In this study, we prepared hydrated and dehydrated Na-zeolites under different conditions using sodium hydroxide (NaOH) and Egyptian kaolin. The synthetic zeolites were characterized by XRD, SEM, specific surface area and their adsorption behavior in…
K. Lizama Allende, T. D. Fletcher and G. Sun Department of Civil Engineering, Monash University, Building 60, Melbourne, VIC 3800, Australia E-mail: [email protected] ABSTRACT The presence of arsenic and heavy metals in drinking water sources poses a serious health risk due to chronic toxicological effects. Constructed wetlands have the potential to remove arsenic and heavy…

At last, the lies about Greece leaving the EU – as if the European Union would want that – have come to an end. From the very beginning of this whole affair, we have consistently written that no such procedure exists within the institutional framework, however much some people might have imagined it. The only…

Smeulders Eindhoven University of Technology, PO Box 513, 5600 MB Eindhoven, The Netherlands In summer, the sun provides more heat than needed to warm residential houses while in winter the heat demand cannot be met by solar energy supply. A solution is to store excess solar energy in a…
With the new data from the Kokkalo area near Petrota, in Northern Evros, the mapping of Greek zeolite is revealing more and more information about these strategic reserves of our country. The recording of geological data and the identification of zeolite tuffs now give us a clearer picture of the location of the deposits of…
