“…A variety of reclamation routes have been explored and reviewed so far, including high calorific smelting, large chemical intensive hydrometallurgy, and energy intensive electrometallurgy [6,[10][11][12]. However, the microbe-to-metal/material interactions have attracted renewed attention for a sustainable reclamation of metals from diversified materials [9].…”

Abstract:Metals with an average crustal abundance of <0.01 ppm, which are high in supply shortage due to soaring demand, can, under the excessive environmental risk and <1% recycling rate of their production, be termed as 'critical' in a limited geo-boundary. A global trend to the green energy and low carbon technologies with geopolitical scenario is challenging for the sustainable reclamation of these metals from secondary resources. Among the available processes, bio-reclamation can be a sustainable technique for extracting and concentrating these metals. Therefore, in the present paper, the potential reclamation of critical metals (including rare earth elements, precious metals, and a common nuclear fuel element, uranium) via their interaction with microbe/s has been reviewed.

“…Jha et al [51] give an extensive overview on the hydrometallurgy recovery and recycling of platinum by leaching of spent catalysts. Despite the standard route of using aqua regia as a leachant, they are focusing on platinum leaching using acidic and alkaline solutions in the presence of oxidizing agents such as nitric acid and hydrogen peroxide, sodium cyanide and iodide solutions.…”

Challenges in Automotive Fuel Cells Recycling

Fuel cell driven cars belong to the 'zero emission' vehicles and should contribute to lower CO 2 emissions. However, they contain platinum, which is known as a critical material in the European Union. This study investigated the potential contribution of recycling fuel cell vehicles (FCV) to satisfy the platinum demand arising from a widespread deployment of fuel cell vehicles in Europe. Based on a qualitative examination of the four consecutive steps in the recycling chain (collection, dismantling, disassembly and pre-processing, material recovery) of fuel cell vehicles, two recycling scenarios were developed. Using dynamic material flow analysis, these two recycling scenarios were applied to two scenarios for the market penetration of fuel cell vehicles in nine European lead markets to deliver both the associated impact on platinum demand and the contribution of recycling for meeting this demand. The diffusion of FCV in Europe will not cause a depletion of platinum resources in the short term, as the calculated 537.06 t and 459.24 t in cumulative platinum requirements are far below the currently estimated global reserves. However, concerns regarding the future development of platinum supply and demand remain.

“…Reciklaža istrošenih auto katalizatora vrši se u najvećim postrojenjima u svetu: Umicore (Belgija), Hereaus (Nemačka), BASF/Engelhard (SAD), Johson Mattey (Velika Britanija) i Nippon/Mitsubishi (Japan) [18]. Umicore je jedno od najvećih postrojenja za reciklažu, gde se godišnje preradi preko 250.000 t sekundarnih sirovina, a proizvede više od 50 t PGM (Pt, Pd, Rh, Ir, Ru), preko 100 t Au i preko 2.400 t Ag.…”

IZVOD -U radu je prikazano stanje i perspektive u proizvodnji platinske grupe metala iz primarnih i sekundarnih sirovina, kao i njihova primena. Na osnovu ponude i potražnje za PGM ukazano je na značaj i potrebu za povećanjem stepena reciklaže sekundarnih sirovina. Pokazano je da se najveće količine platinskih metala koriste u proizvodnji auto katalizatora i da je njihova reciklaža jako bitna za očuvanje prirodnih resursa. Reciklaža i održivi razvoj 7 (2014) 9-21Pregledni rad UDK 628.4.037:546.91 UVOD Platinska grupa metala (PGM) obuhvata platinu, paladijum, iridijum, rodijum, osmijum i rutenijum, od kojih je platina najvažnija pa cela grupa nosi naziv "platinski metali". Platinski metali se odlikuju visokim tačkama topljenja, velikom hemijskom otpornošću, većinom su rastegljivi i kovni, grade brojne legure i komplekse [1].Platinski metali spadaju u izrazito retke elemente. U izveštaju Evropske Komisije iz 2010.godine [2], 14 sirovina u Evropi označeno je kao "kritične" na osnovu ekonomskih parametara i dostupnosti istih, u okviru kojih se nalazi i PGM (pored grupe retkih metala,
