    (Unknown, 2018-02-06) Dino, Giovanna Antonella; Rossetti, Piergiorgio; Lorenzi, Alessio; Mister, Ivan; Cazzaniga, Alberto; Coulon, Frederic; Griffiths, Zoe; Wagland, Stuart
    In recent years, resource scarcity has emphasised a need to transition from a linear to a circular flow of resources. Securing supplies of critical and secondary raw materials (CRM/SRM) for the manufacturing industry is at the forefront of industrial challenges, especially in Europe, USA and Asia. A key step towards achieving resource efficiency, is to recover these materials from anthropogenic waste deposits, such as urban landfill sites and extractive waste facilities. This means breaking away from the traditional linear use of resources to a closed-loop approach that allows maximum recovery of resources from waste. The management of extractive waste deposits and resource recovery is closely linked to the concept of urban mining. In this paper, we present a case study illustrating the feasibility of recovering SRM from EW facilities and discuss the pros and cons of undertaking such activities.

    Investigation of municipal solid waste (MSW) and industrial landfills as a potential source of secondary raw materials
    (2018-03-31) Särkkä, Heikki; Kaartinen, Tommi; Hannus, Esa; Hirvonen, Sami; Valjus, Tuire; Lerssi, Jouni; Dino, Giovanna A.; Rossetti, Piergiorgio; Griffiths, Zoe; Wagland, Stuart T.; Coulon, Frederic
    Many of the secondary raw materials (SRM) in landfills constitute valuable and scarce natural resources. It has already been recognised that the recovery of these elements is critical for the sustainability of a number of industries and SRM recov¬ery from anthropogenic waste deposits represents a significant opportunity. In this study, the characterisation of the different waste fractions and the amount of SRM that can potentially be recovered from two landfill sites in Finland is presented. The first site was a municipal solid waste (MSW) landfill site and it was specifically in¬vestigated for its metals, SRM, plastics, wood, paper, and cardboard content as well as its fine fraction (<20 mm). The second site was an industrial landfill site contain¬ing residual wastes from industrial processes including 1) aluminium salt slag from refining process of aluminium scrap and 2) shredding residues from automobiles, household appliances and other metals containing waste. This site was investigated for its metals and SRM recovery potential as well as its fine fraction. Results suggest that the fine fraction offers opportunities for metal (Cr, Cu, Ni, Pb, and Zn) and SRM extraction and recovery from both landfill site types while the chemical composition of the industrial waste landfill offered greater opporutinity as it was comparable to typical aluminium salt slags. Nevertheless, the concentrations of rare earth metals (REE) and other valuable elements were low even in comparison with the concentra¬tions found in the Earth’s crust. Therefore mining landfill sites only for their metals or SRM content is not expected to be financially viable. However, other opportunities, such as waste-derived fuels from excavated materials especially at MSW landfill sites, still exists and fosters the application and feasibility of landfill mining.

    Landfill mining from extractive waste facilities: The importance of a correct site characterisation and evaluation of the potentialities. A case study from Italy
    (Elsevier, 2018-05-01) Dino, Giovanna Antonella; Rossetti, Piergiorgio; Perotti, Luigi; Alberto, Walter; Sarkka, Heikki; Coulon, Frederic; Wagland, Stuart; Griffiths, Zoe; Rodeghiero, Franco
    Raw materials (RM) and critical raw materials (CRM; EC, 2017) supply is essential to both the maintenance and development of the EU economy as its industries rely on a steady RM supply. Thus, securing a sustainable RM and CRM supply and their circular use in the economy is of importance at EU level and beyond (Blengini et al., 2017, Coulomb et al., 2015, Vidal-Legaz et al., 2016). Furthermore, the developments of clean technologies coupled with economic growth exacerbate the short and long-term demand and needs (Blagoeva et al., 2016, Pavel and Tzimas, 2016). For example, Habib and Wenzel (2014) reported that the necessary supply Nd and Dy will grow from 10.0 Gg to 54.5 Gg and 0.5 Gg to 4.95 Gg respectively from 2010 to 2050.

    Smart ground project: a new approach to data accessibility and collection for raw materials and secondary raw materials in Europe
    (Gheorghe Asachi Technical University of Iasi, 2017-12-31) Dino, Giovanna Antonella; Rossetti, Piergiorgio; Biglia, Giulio; Sapino, Maria Luisa; Di Mauro, Francesco; Särkkä, Heikki; Coulon, Frederic; Gomes, Diogo; Parejo-Bravo, Lucía; Zapata Aranda, Pilar; Lopez, Antonia Lorenzo; Lopez, Jorge; Garamvölgyi, Ernő; Stojanovic, Sandra; Pizza, Antonietta; de la Feld, Marco
    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.

    SMART GROUND Project: SMART data collection and integration platform to enhance availability and accessibility of data and information in the EU territory on secondary raw materials
    (Elsevier, 2016-11-29) Dino, Giovanna Antonella; Rossetti, Piergiorgio; Biglia, Giulio; Coulon, Frederic; Gomes, Diogo; Wagland, Stuart Thomas; Luste, Sami; Särkkä, Heikki; Ver, Csaba; Delafeld, Marco; Pizza, Antonietta
    The issue of resource security has come to the forefront of the debate as Critical Materials (CRM) and Raw Materials (RM) supply is fundamental to maintain and develop EU economy. Considering the increasing scarcity and raising prices of RM, their recycling and recovery from anthropogenic deposits is essential. To date there is no homogeneous inventory available of SRM and CRM present in EU landfills, and best management practices to recover SRM from landfill activities are inefficient. In this context, the EU SMART GROUND project intends to foster resource recovery in landfills by improving the availability and the accessibility of data and information on SRM in the EU.

    Towards sustainable mining: exploiting raw materials from extractive waste facilities
    (MDPI, 2020-03-18) Dino, Giovanna Antonella; Cavallo, Alessandro; Rossetti, Piergiorgio; Garamvölgyi, Ernő; Sándor, Renáta; Coulon, Frederic
    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.
