Zeolite in the Environment

zeolite will make a difference in Greece and for Greece only and solely if our own people believe in it and put it into practice realising that they are helping our homeland because everything else is of no concern to us; what matters is development for the people, with respect for the environment, because we want future generations to live freely, just as we do.

Postgraduate Thesis – Author: Irini Papadimitriou, Supervisor: Ch. Karagianni, Associate Professor, National Technical University of Athens, School of Chemical Engineering, 2010. The problem of widespread pollution incidents involving heavy metals and toxic chemicals, due to the uncontrolled management of toxic and hazardous industrial waste, has arisen not only in Greece but also in other European countries, such as France, Italy, Ireland, etc.• It is recognised as a very serious and pressing issue that must be addressed as a European problem requiring immediate action. On the one hand, the priority is the effective management of environmental risk, with the aim of ... Read more

PhD Thesis – Author: Dionysiou, Ourania-Nina S., Supervisor: Misopolinos, Nikolaos, Aristotle University of Thessaloniki, School of Agriculture, 2010. This study investigated certain conditions that influence the adsorption of B and P on surface-modified natural zeolite (clinoptilolite), with hexadecyl-trimethyl-ammonium bromide (C19H42BrN or HDTMA–Br), with a view to its use as a decontamination agent for irrigation water and aquatic systems. Specifically, the following were investigated: (a) the effect of washing the zeolite with HCl prior to its modification, and (b) the effect of increasing the pH on the adsorption of B by the zeolite. Subsequently, the following were investigated: c) the effect ... Read more

Doctoral thesis, Author: Tzamos, Evangelos Ioannis, Supervisor: Filippidis, A., Professor, Aristotle University of Thessaloniki, School of Sciences, Department of Geology. The zeolite-bearing volcanic clastic sediments of Southern Xerovouni (Avdella, Evros Prefecture) contain, on average, 57% by weight of HEU-type zeolite, 6% by weight of smectite, 3% by weight of marmatite (a total of 66% by weight of microporous minerals), 19% by weight of astrios, 10% by weight of cristobalite and 5% by weight of quartz (a total of 34% non-microporous minerals). The chemical composition of these sediments is: 69.9% by weight SiO₂, 13.2% by weight Al₂O₃, 1.2% by weight Fe₂O₃, ... Read more

Doctoral Thesis THOMA A. KOTSOPOULOU, Graduate in Agricultural Science, Graduate in Civil Engineering, MSc, IKY Scholarship Holder SUPERVISOR: Prof. Gerasimos Martzopoulos This study investigated the effect of adding different quantities of natural zeolite on the anaerobic degradation of pig farm effluent. In particular, the effect of adding zeolite on increasing the energy yield of the effluent (greater quantity of methane, energy yield over a short period of time) was examined. Furthermore, the impact of introducing zeolite on the reduction of solids, volatile solids and BOD5 (environmental factors) was investigated. Two preliminary measurements were carried out, which served as a guide ... Read more

Interview with Nikos Lygeros on Greek zeolite on Radio Evros, 20 March 2015 Professor Nikos Lygeros speaks on Soula Kapetanidou’s programme about developments in Greek zeolite and how it can help tackle unemployment in the widerregion of Thrace and Macedonia. www.radioevros.gr

Final decision on Greek zeolite – N. Lygeros Final decision on Greek zeolite – N. Lygeros The final decision on the exploration licence for Greek zeolite marks the beginning of a new and revolutionary phase for our country, as, for the first time in history, zeolite is becoming a reality. The approval of the study entitled ‘Restoration of the area surrounding the zeolite exploration site in the Petrota Municipal District’ marks the starting point for Greece. Our struggle has thus been vindicated, as our vision is set to become a reality. Even before the survey began, measures were approved for ... Read more

Technical characteristics of zeolite utilisation – Nikos Lygeros | Zeolife.gr Technical characteristics of zeolite utilisation – Nikos Lygeros To avoid any comparison with any other mining operation, it is useful to be aware of the technical characteristics of zeolite mining in Thrace, as it is now widely recognised that all stakeholders are aware that the project must go ahead, and indeed with vigour. The operation of the zeolite quarry will, of course, be open-cast, as access is direct and will be carried out using the method of straight, successive open-cut benches, which is the most widely recognised. The rock is ... Read more

Chemical analysis of Greek zeolite – N. Lygeros | Zeolife.gr As we are now entering a new phase for Greek zeolite, it is good to have technical data rather than just estimates, as we can carry out XRD and EDX measurements that enable us to avoid generalisations. First and foremost, we should note that the zeolite variety we are examining within the zeolitic tuff is clinoptilolite, and its formula is as follows: (Na,K,Ca)₂₋₃Al₃(Al,Si)₂Si₁₃O₃₆·12H₂O. Zeolites generally contain silicon (Si) and aluminium (Al). Clinoptilolite, however, is additionally characterised by the following elements: Na, K, Ca. Consequently, these are present in the chemical analysis ... Read more
