metal binding by bacteria from uranium mining waste piles and its technological applications
Biotechnology Advances, 2006Co-Authors: Katrin Pollmann, Mohamed L. Merroun, Johannes Raff, Karim Fahmy, Sonja SelenskapobellAbstract:Abstract Uranium mining waste piles, heavily polluted with radionuclides and other toxic metals, are a reservoir for bacteria that have evolved special strategies to survive in these extreme environments. Understanding the mechanisms of bacterial adaptation may enable the development of novel bioremediation strategies and other technological applications. Cell isolates of Bacillus sphaericus JG-A12 from a uranium mining waste pile in Germany are able to accumulate high amounts of toxic metals such as U, Cu, Pb, Al, and Cd as well as precious metals. Some of these metals, i.e. U, Cu, Pd(II), Pt(II) and Au(III), are also bound by the highly orderd paracrystalline proteinaceous surface layer (S-layer) that envelopes the cells of this strain. These special capabilities of the cells and the S-layer proteins of B. sphaericus JG-A12 are highly interesting for the clean-up of uranium contaminated waste waters, for the recovery of precious metals from Electronic Wastes, and for the production of metal nanoclusters. The fabricated nanoparticles are promising for the development of novel catalysts.This work reviews the molecular biology of the S-layer of the strain JG-A12 and the S-layer dependent interactions of the bacterial cells with metals. It presents future perspectives for their application in bioremediation and nanotechnology.

ceres co processing of coal mine Electronic Wastes novel resources for a sustainable future
Hydrometallurgy, 2020Co-Authors: Christopher G. Bryan, Anne-gwenaëlle Guezennec, S Gaydardzhiev, P Wavrer, B J Williamson, J Calusmoszko, Q Van Haute, R FrączekAbstract:Abstract Most coal mines produce waste which has the potential to generate acid mine drainage (AMD). If not properly managed, this can cause environmental damage through contamination of ground and surface waters and soils for hundreds of years. At the same time, the pace of technological development means that most electrical and Electronic equipment becomes obsolete within a matter of years, resulting in the generation of vast quantities of Electronic waste (e-waste). Where this cannot be recycled, it must be discarded. The CEReS concept is a co-processing approach for both waste streams to produce metals and other valuable products, and to reduce or eliminate the their environmental impact. This brings together two waste streams from opposite ends of the supply chain; turning each into a novel resource in a single, coherent ‘grave-to-cradle’ process. This industrial ecology approach is key to supporting a circular economy whilst securing the sustainable supply of critical raw materials. The project successfully elaborated a novel co-processing flow-sheet comprising: (i) the accelerated bioweathering of AMD-generating coal production Wastes to generate a biolixiviant; (ii) the pyrolysis and catalytic cracking of low-grade PCBs to produce hydrocarbon fuel, a halogen brine and a Cu-rich char; (iii) the leaching of base metals from the char using the biolixiviant; (iv) the reuse of stabilised coal Wastes; and (v) the full or partial (as enriched substrates) recovery of valuable metals. These process units were demonstrated individually at lab-pilot scale. The data were then used to validate the entire flow-sheet in an integrated process simulator and determine the economic balance. Finally, an LCA approach was used to demonstrate the environmental benefits of the CEReS process over the status quo.

If not properly managed, this can cause environmental damage through contamination of 18 ground and surface waters and soils for hundreds of years. At the same time, the pace of 19 technological development means that most electrical and Electronic equipment becomes obsolete 20 within a matter of years, resulting in the generation of vast quantities of Electronic waste (e-waste). 21 Where this cannot be recycled, it must be discarded.

CEReS -Co-processing of Coal Mine & Electronic Wastes: Novel Resources for a Sustainable Future
2019Co-Authors: Christopher G. Bryan, B Williamson, J Calus-moszko, Q Van Haute, Anne-gwenaëlle Guezennec, S Gaydardzhiev, P Wavrer, R FrączekAbstract:Many coal mines produce waste which causes acid mine drainage (AMD) potentially resulting in severe environmental damage. This drainage can be treated, but most Wastes will continue to produce such drainage for hundreds of years. Therefore, longer term, permanent solutions are needed. At the same time, the pace of technological development means most electrical and Electronic equipment becomes obsolete within a matter of years. This results in the generation of vast and growing quantities of Electronic waste (e-waste) every year. Where this cannot be recycled, it must be discarded. CEReS was a 3.2 M€ RFCS-funded project comprising eight partners from five countries. It targeted the development of a co-processing approach to treat these waste streams to produce metals and other valuable products, while eliminating their environmental impact. This brings together two waste streams from opposite ends of the supply chain (for which no alternative treatment option exists); turning each into a novel resource in a single, coherent 'grave-to-cradle' process. This industrial ecology approach is key to supporting a circular economy while securing the sustainable supply of critical raw materials. The project successfully elaborated a novel co-processing flow-sheet comprising: (i) the accelerated weathering of AMD-generating coal production Wastes to generate a biolixiviant; (ii) the pyrolysis and catalytic cracking of low-grade PCBs to produce hydrocarbon fuel, a halogen brine a Cu-rich char; (iii) the leaching of base metals from the char using the biolixiviant; (iv) the reuse of the stabilised coal Wastes; and (v) the recovery of valuable metal while concentrating precious and critical metals into enriched substrates. These individual process units were demonstrated individually at lab-pilot scale. The data were then used to validate the entire flow-sheet in an integrated process simulator. Finally an LCA approach was used to demonstrate the environmental benefits of the CEReS process over the status quo.
