Abstract:

This project will materialize in transdisciplinary collaboration between the team of specialists: archaeologists, archaeometry, and computer scientists and will lead to the development of 3D technologies (3D laser scanners and photogrammetric methods) for storing information in digital format about the Dobrogean medieval heritage built of stone (Sacidava Fortress) which has not been investigated so far. The new 3D technologies proposed to be used for scanning, photography and moving, will serve to map the archaeological site and will be supplemented with physicochemical and biological studies, through analytical techniques of structural, compositional, and morphological characteristics to assess chromatic uniformity, degradation status, and other information related to the period, geographical location, shape, construction material, level of degradation. It is known that the artifacts are particularly vulnerable, and their release from the environment where they were buried accelerates the processes of corrosion and degradation, which can lead to the destruction of archaeological evidence.

The characterization of historical materials will include non-destructive methods in situ and in the laboratory: chromatic analysis, UV-Vis and FTIR spectroscopy, X-ray diffraction and fluorescence, Raman spectroscopy, optical microscopy, SEM / EDS, thermal analysis, compressive strength, strength to frost, the crystallization of salts. Based on the results obtained, tests will be performed on model substrates prepared in the laboratory and on real samples (received from site archaeologists, in compliance with legislation) by using nanomaterials (substituted hydroxyapatite derivatives) that meet the criteria of compatibility with historical materials. The mapping of this archeological site, its degradation state, the elaboration of new solutions for the conservation of the stone surfaces exposed in the atmosphere and humidity due to the proximity of the Danube, will be achieved.

Abstract:

Although in 2016, at global level, the quantity of WEEE was over 45Mt (increasing 3-5% yearly), the estimated recycling rate only reaches 15-20%. Out of the total WEEE quantity, IT and telecommunication equipment waste (WEITT) represents c.a.15%, while printed circuit board waste, albeit only 3-6% of the total DEIT waste, concentrates 40% of the recoverable metals. At international level, the usual industrial technologies are mainly based on physical-mechanical and pyro-metallurgic procedures, but require high energy consumption and generate toxic by-products. At national level, reported research on WEITT processing is limited to the laboratory, while industrial processing agents only collect DEIT for export.

The consortium, composed of the Technical and Babeș-Bolyai universities of Cluj-Napoca, "1 Decembrie 1918" of Alba Iulia, Technical "Gheorghe Asachi" of Iași, INDO-INOE 2000 Research Institute for Analytical Instrumentation subsidiary ICIA and the National Institute for Research & Development in Chemistry and Petrochemistry, will elaborate, test and validate a complex of installations and optimised technologies for the integral reclaiming of WEITT materials, based on the following principles: 1) minimal energy consumption and reduced quantities of secondary waste, with reduced environmental impact, 2) smart disassembling and separation (mechanical, electrical and electrochemical) in order to obtain new or recycled materials with high purity and high economical value, 3) valorification of resulted plastic materials through non-polluting chemical technologies and their reintroduction in the production process, 4) development of a platform for monitoring environmental impacts and for learning reclaiming technologies for DEIT material 5) transfer of the developed technologies to companies in the Romanian reclaiming and recycling industry.
