“…Another application is the use of fine sized ASR as a binder and/or aggregate in asphalt [56,57]. Incorporation of ASR in asphalt reduces the oxidation of the asphalt and increases the elastic memory, thus preventing fatigue cracking [56].…”

“…Incorporation of ASR in asphalt reduces the oxidation of the asphalt and increases the elastic memory, thus preventing fatigue cracking [56]. Rosetti et al [57] showed that granules, produced by mixing ASR with binding materials (lime or cement), fly ash and a densifying agent, were a suitable aggregate in asphalt mixes. In their experiments, the optimum ASR to fly ash ratio was 1 to 1, but the optimum mix of the different constituent materials and the possibility of industrial production still need further investigation.…”

“…Granulation processes may be applied to obtain a significant particle size enlargement, which is achieved by mixing a liquid binder with a fine particle size material in a rotary drum or similar device [5,6]. Recently, a number of studies have focused on the coupling of the two above mentioned techniques in order to obtain aggregates from the treatment of several waste material, such as contaminated soil [7], municipal solid waste incinerator bottom [8] and fly ash [9,10], automotive shredder residues [11]. It was proved that such a treatment may be effective in obtaining pellets with sufficient mechanical strength to be reused in civil engineering applications and exhibiting a decreased release of toxic elements, such as As, Pb, Cd and Hg [7].…”

This work reports the results of a lab-scale investigation carried out to assess the effects of a stabilization/solidification-granulation treatment applied to an industrial soil sampled from a brownfield site. Preliminary tests were performed on a natural soil to investigate the effects of the operating conditions and mixture formulations on the physical and mechanical properties of the product. In a second phase, the process was tested on the brownfield industrial soil, applying the operating conditions and binder type that provided the best results in the preliminary tests. The suitability of the obtained granules for use as artificial aggregates was assessed through the analysis of the particle size distribution, mechanical strength and inorganic contaminant leaching. With regard to the industrial soil, the best mechanical performance, comparable to that of natural gravel, was achieved with the following mixture formulation: 30% wt. of cement R 52.5, a water/solid ratio equal to 0.14 l/kg and an additive/solid ratio equal to 2 % wt. The alkaline pH of the leachates as well as the leaching behaviour of the cement showed to exert a great influence on the release of some critical metals from the obtained granules, such as Ba, Cr, Mo and Cu.

“…In this study, car fluff, also known as ASR (Automotive Shredder Residue), that is, the residue resulting from the dismantling of automotive vehicles (Vermeulen et al, 2011) is considered. Fluff is a highly heterogeneous material composed mainly of plastic, rubber/elastomer, metals, glass, textiles and other rubbles (Alunno Rossetti et al, 2006;Ruffino et al, 2014). …”

The aim of this study is the thermal recovery of manganese and zinc from a mixture of zinc-carbon and alkaline spent batteries containing 40.9% of Mn and 30.1% of Zn after a preliminary physical treatment. Separation of the metals is carried out on the basis of their different phase change temperatures, the boiling point of zinc being 906°C and 1564°C that of Mn 3 O 4 , the main Mn-bearing phase in the mixture. After wet comminution and sieving to remove the anodic collectors and most of the chlorides contained in the mixture, chemical and X-Ray Powder Diffraction (XRPD) analyses were performed. The mixture was heated in CO 2 atmosphere and the temperature raised, thus permitting the zinc oxide to be reduced to metallic zinc by the carbon present in the original mixture. Other tests were carried out by addition to the mixture of activated charcoal (95% C) or of the automotive shredder residue (fluff) containing 45% C.A zinc product was obtained suitable, after refining, for the production of new batteries. The treatment residue consisted of manganese and iron oxides that could be used to produce manganese-iron alloys. From these results, an integrated process for the recovery of the two metals was proposed.
