91. An extracellular polymeric substance quickly chelates mercury(II) with N-heterocyclic groupsFranco Baldi, Michele Gallo, Salvatore Daniale, Dario Battistel, Claudia Faleri, Alojz Kodre, Iztok Arčon, 2017, izvirni znanstveni članek Opis: A strain of Klebsiella oxytoca DSM 29614 is grown on sodium citrate in the presence of 50 mg l−1 of Hg as Hg(NO3)2. During growth, the strain produces an extracellular polymeric substance (EPS), constituted by a mixture of proteins and a specific exopolysaccharide. The protein components, derived from the outer membrane of cells, are co-extracted with the extracellular exopolysaccharide using ethanol. The extracted EPS contains 7.5% of Hg (total amount). This indicates that EPS is an excellent material for the biosorption of Hg2+, through chemical complexation with the EPS components. The binding capacity of these species towards Hg2+ is studied by cyclic voltammetry, and Hg L3-edge XANES and EXAFS spectroscopy. The results found indicate that Hg2+ is mainly bound to the nitrogen of the imidazole ring or other N-heterocycle compounds. The hydroxyl moities of sugars and/or the carboxyl groups of two glucuronic acids in the polysaccharide can also play an important role in sequestring Hg2+ ions. However, N-heterocyclic groups of proteins bind Hg2+ faster than hydroxyl and carboxyl groups of the polysaccharide.

96. ASSESSMENT OF THE DEVELOPMENT POTENTIAL OF FOREST-WOOD PROCESSING CHAINSlavica Ilc, 2016, magistrsko delo Opis: Slovenia is the third most forested country in Europe. Nevertheless, in the last twenty five years this natural wealth did not get the adequate role in national development strategies, which unnecessary reduced their sustainability potential and lead the Slovenian forest-wood industry in a very bad situation. The forest-based sector in Europe is in a period of profound structural changes, which requires reassessment of the wood-chain products outlook.
In the master’s thesis, the importance of integration of forestry and wood industry has been evaluated with the meaningful connection of different analytical methods: material flow analysis (MFA), SWOT analysis and life cycle assessment (LCA). With comparison of the roundwood and sawnwood material flow in Slovenia, Italy and Austria, the critical points in the Slovenian forest-wood chain were identified. In contrast to Austria and Italy, where wood is intensively reworked, Slovenia exports large amounts of untreated roundwood. As a consequence, the gross value added (GVA) per employee of wood sector in Slovenia reaches only 40 % of GVA in Austria and 50 % of GVA in Italy. Not only MFA, but also the SWOT and LCA analyses show, that wood processing into finished products is important both in terms of the value added and the environmental impact, as well as for more decisive shift of the economy towards a low-carbon society.
Slovenian economy could take advantage of its sustainable development potential to a great extent by increasing the level of raw material self-sufficiency and energy independency. It is essential to re-establish forest-wood processing chain, to rework wood at home into products with the highest added value, and to use wood residues as renewable feedstock in green chemistry industry and for transformation into energy with novel technologies. Slovenian vision of sustainable economy has great potential, but requires enhanced cross-sectoral integration of forestry, wood processing, construction, chemistry and energy.
Ključne besede: sustainability, forest-wood processing chain, development potential, material flow analysis (MFA), SWOT analysis, life cycle assessment (LCA)

97. EVALUATION OF MARINE SEDIMENTS FROM THE PORT OF LUKA KOPER FROM THE ENVIRONMENTAL PERSPECTIVE AND IN TERMS OF THEIR USABILITY IN THE BRICK INDUSTRYPatrik Baksa, 2016, magistrsko delo Opis: The majority of the world’s goods are transported over water and dredging is essential for the development of harbors and ports. Therefore, the management of dredged material is a worldwide issue. Due to its chemical and petrographic, mineralogical and homogeneity composition, marine sediments are an appropriate raw material to use in the brick industry. Marine sediments can serve as raw material for the production of clay blocks, roofing and ceramic tiles.
Different analyses were carried out in order to determine if the dredged material from the Port of Koper is environmentally friendly and suitable to use in the brick industry. These analyses included: a chemical analysis, a mineralogical analysis, a particle size analysis and a chloride content (Cl-) analysis, and tests of firing in a gradient furnace. Furthermore, tests of mechanical properties, as well as tests of frost-resistance of the samples were carried out.
On the basis of primary analyses and samples prepared in a lab, it was established that marine sediments from the Port of Koper without any additives are only conditionally suitable as a source material for producing brick products. In collaboration with Gorica brickworks (Goriške opekarne), a pilot production from a mixture of 60% component B from Gorica brickworks and 40% component A (marine sediments) from the Port of Koper was prepared. Different tests showed the mixture could be appropriate for brick production.
Ključne besede: marine sediments, recycling, clay bricks, chemical analysis, mechanical properties, brick production.
