“…The combustion of tire waste is mostly carried out in cement kiln factories due to its high-energy contents (Conesa et al, 2008). Although the burning process produces energy, but it also causes air and waterborne pollution with detrimental effects on the environment and public health (Miandad et al, 2017a(Miandad et al, , 2016aKhan et al, 2017). In addition, since the 1970s increase in the (Buekens, 1977).…”

 Catalytic and non-catalytic pyrolysis of tire waste was carried out at pilot-scale  Non-catalytic pyrolysis produced highest liquid oil as compared to catalytic pyrolysis  Natural zeolite, zeolite (H-SDUSY), Al2O3 and Ca(OH)2 catalysts were used  Use of various catalysts improved the quality of liquid oil  Oil from both processes mainly contained aromatic with some aliphatic compounds

Microbial electrolysis cells (MECs) have been studied in a wide range of potential applications such as recalcitrant pollutants removal, chemicals synthesis, resources recovery and biosensors. However, MEC technology is still in its infancy and poses serious challenges for practical large‐scale applications. To understand the diversified applications of MEC, this review aims to explore MEC applications in the following contexts: an overview of MEC for energy generation and recycling such as hydrogen, methane, formic acid and hydrogen peroxide; contaminant removal, specifically complex organic pollutants and inorganic pollutants; as a sensor; as well as resource recovery. New concepts of MEC technology; configuration optimization; electron transfer pathways in biocathodes, and coupling with other technologies for value‐added applications such as MEC‐anaerobic digestion, MEC‐MFC, MEC‐MDC and bio‐E‐Fenton system are discussed. Finally, challenges and outlooks are suggested. The review aims to assist researchers and engineers to understand the latest trends in MEC technologies and applications. © 2018 Society of Chemical Industry

“…In these bioelectrochemical systems, living electroactive microorganisms interact with solid electrodes . Biodegradable organic materials are oxidized by microorganisms in the anodic chamber to generate an electron flow (i.e., current) toward the cathodic compartment, where electrons can be used in an oxygen reduction reaction resulting in the direct production of electricity in microbial fuel cells (MFCs), as well as the production of hydrogen, value‐added chemicals, and the removal of contaminants, such as metal ions in microbial electrolysis cells (MECs) . Interestingly, sulphate reduction is facilitated at a MEC cathode, thus facilitating the proliferation and microbial activity of SRBs and, therefore, facilitating the removal of metal ions …”

This work describes laboratory experiments aimed at evaluating the feasibility of removing heavy metals from metal-contaminated water in flowthrough microbial electrolysis cells (MECs) with peat moss as a source of organic carbon. MECs were assembled in upflow glass columns containing granular activated carbon (GAC) bioelectrodes preceded by a layer of peat moss. The MECs were fed with metal-contaminated surface water collected at a firing range. At hydraulic retention times (HRT) of 4-6 days, up to 99 % removal of Pb, Zn, Cu, and Fe was observed. The removal efficiency of Zn and Cu declined at an HRT of 1.7 days, while effluent Pb concentration remained below the detection limit for all of the HRTs tested. Metal extraction from MEC compartments showed an accumulation of metals in both the peat moss layer and the GAC cathode, i.e., the removal was achieved by a combination of anaerobic and bioelectrochemical pathways of metal reduction. A proliferation of sulphate reducing bacteria in the peat moss layer and electroactive species in GAC electrodes was confirmed by biomolecular analysis. The proposed flowthrough system, which combines sulphate-reducing and electroactive microbial activities to achieve near-complete metal removal, can be used for removing a broad range of heavy metals from contaminated water in a low-cost passive flow treatment system.
