Towards sustainable mining: exploiting raw materials from extractive waste facilities
The focus of the present research is on the exploitation of extractive waste to recover raw materials, considering the technological and economic factors, together with the environmental impacts, associated with extractive waste quarrying and dressing activities. The present study, based on a case history from Northern Italy (Montorfano and Baveno granite quarrying area), was intended to validate the presented interdisciplinary approach for evaluating economic and environmental impacts associated with extractive waste facility exploitation (from granite waste to products for the ceramic industry and by-products for the building industry). A shared methodology was applied to determine extractive waste characteristics (geochemistry, petrography, and mineralogy), waste volume (geophysical, topographic, and morphologic 3D characterization) and potential exploitable products and by-products. Meanwhile, a Life Cycle Assessment (LCA) was applied to determine the environmental impacts associated with the extraction and processing phases
Smart ground project: a new approach to data accessibility and collection for raw materials and secondary raw materials in Europe
Steady Raw Materials (RM) supply is essential for the EU economy and increasingly under pressure to sustain the businesses and industries demand. The supply of RM is not only a matter of availability of primary but also of secondary raw materials (SRM). In fact a great amount of waste can be regained as practical and valuable SRM by enhancing the recovery processes from industrial, mining and municipal landfill sites, especially if we consider that Europe is highly dependent on the imports of several RM. Nevertheless, there is to date no inventory of SRM at EU level. Smart Ground project aims to facilitate the availability and accessibility of data and information on SRM in the EU, as well as creating synergy and collaboration between the different stakeholders involved in the SRM value chain. In order to do so, the Smart Ground consortium is carrying out a set of activities to integrate in a single EU database all the data from existing sources and new information retrieving pilot landfills as progress is made. Such database will enable the exchange of contacts and information among the relevant stakeholders, interested in providing or obtaining SRM. Finally, Smart Ground project will also spin out the SRM economy and employment thanks to targeted training activities, organized during congresses and dedicated meeting with stakeholders and end users interested in calculating the potentiality for SRM recovery from selected landfills, contemporary constituting a dedicated network of stakeholders committed to cost-effective research, technology transfer and training
SMARTGROUND: Hulladéklerakók feltárásának környezeti, gazdasági és társadalmi hatásai
Az elsĹ‘dleges nyersanyagok egyre fontosabbak az ipar számára, azonban kĂ©szletĂĽk egyre csökken. Azonban az EurĂłpában találhatĂł több százezer hulladĂ©klerakĂł másodnyersanyag forráskĂ©nt jelentĹ‘s potenciállal bĂr. Jelenleg a rendelkezĂ©sre állĂł tudás, adatbázisok Ă©s technolĂłgiai eljárások hiányosnak tűnnek, egy racionálisabb hulladĂ©kgazdálkodási gyakorlattal azonban a nyersanyagok hatĂ©konyabb felhasználása, egyĂşttal hulladĂ©kcsökkentĂ©s Ă©rhetĹ‘ el. Ezzel összefĂĽggĂ©sben a másodnyersanyagokra vonatkozĂł informáciĂłk hozzáfĂ©rhetĹ‘sĂ©gĂ©nek Ă©s rendelkezĂ©sre állásának fejlesztĂ©se egy közös, EurĂłpai informatikai platform kialakĂtásával javĂthatja a másodlagos nyersanyagokal kapcsolatos gazdasági Ă©s foglalkoztatási potenciált az EU-ban.
A téma vizsgálatára indult 2015. októberében a nemzetközi SmartGround projekt, melynek célja a hulladéklerakókból kinyerhető másodnyersanyagok technológiai, gazdasági, környezeti, valamint szociális hatásainak a vizsgálata
SmartGround projekt – adatintegráciĂłs platform a másodnyersanyagok hasznosĂtásáért
<p>Raw Materials are becoming more and more important for the EU economy but their accessibility is getting crucial, especially the Critical Raw Materials. In Europe there are between 150k to 500k highly variable landfills, thus the EU Secondary Raw Materials (SRM) potential is significant. Existing knowledge, reporting standards and inventory actually used seem to be inefficient. Rational waste management practices could lead to a more efficient exploitation of raw materials and to waste reduction. In this context, the improvement of the availability and accessibility of data and information on SRM together with the creation of European networks will improve the SRM economic and employment potential in EU. Horizon 2020 project, called SmartGround (SMART data collection and inteGRation platform to enhance availability and accessibility of data and infOrmation in the EU territory on SecoNDary Raw Materials) supports these activities with international data on landfills, common geoinformation system for information management, data fusion and analysis and prediction tools.</p
