Hazardous waste disposal via incineration generates a substantial amount of ashes and slags which pose an environmental risk due to their toxicity. Currently, these residues are deposited in landfills with loss potentially recyclable raw material. In this study, the use acidophilic bioleaching bacteria (Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans, Leptospirillum ferrooxidans) as environmentally friendly, efficient strategy for recovery valuable metals from was investigated....
Microbial electrolysis cells equipped with modified carbon felt electrodes showed enhanced long-term performance of organic degradation and CO<sub>2</sub> conversion to CH<sub>4</sub>.
Sustainable technologies for energy production and storage are currently in great demand. Bioelectrochemical systems (BESs) offer promising solutions both. Several attempts have been made to improve carbon felt electrode characteristics with various pretreatments order enhance performance. This study was motivated by gaps current knowledge of the impact on enrichment microbial composition bioelectrochemical systems. Therefore, electrodes were treated poly(neutral red), chitosan, or...
Decreasing ore grades and an increasing consumption of metals has led to a shortage important primary raw materials. Therefore, the urban mining different deposits anthropogenic stocks is interest. Basic oxygen furnace (BOF) slag produced in huge quantities with so-called Linz-Donawitz process contains up 5.2, 0.9, 0.1, 0.07% Mn, Al, Cr, V, respectively. In present study, sulfur-oxidizing Acidithiobacillus thiooxidans iron- ferridurans were applied batch stirred tank experiments investigate...
Metal recycling is essential for strengthening a circular economy. Microbial leaching (bioleaching) an economical and environmentally friendly technology widely used to extract metals from insoluble ores or secondary resources such as dust, ashes, slags. On the other hand, microbial electrolysis cells (MECs) would offer energy-efficient application recovering valuable aqueous solution. In this study, we investigated MEC Zn recovery metal-laden bioleachate first time by applying constant...
Carbon capture and utilization has been proposed as one strategy to combat global warming. Microbial electrolysis cells (MECs) combine the biological conversion of carbon dioxide (CO2) with formation valuable products such methane. This study was motivated by surprising gap in current knowledge about real exhaust gas a CO2 source for methane production fully biocatalyzed MEC. Therefore, two steel mill off-gases differing composition were tested two-chamber MEC, consisting an organic...
Metallurgical dusts are by-products from steel manufacturing. The high iron content of cast house dust (~64%) makes this by-product an interesting feedstock alternative. Therefore, its return into the internal steelmaking circuit, specifically in sinter plant, is a common practice industry. However, fraction also contains heavy metals, as zinc. As result re-entry zinc process, concentration blast furnace flue gas increases. This prevents full recirculation process despite relatively (~35%),...
The generation of currently partially recyclable metallurgical dusts during the steel production represents a challenge for realization circular economy in this industrial sector. Due to high iron concentration, reutilization blast furnace and cast house internal crude processes, is state art. However, heavy metal impurities such as zinc, act an interference due diverse negative effects. aim study utilize Acidithiobacillus ferrooxidans, iron- sulfur-oxidizing bacteria, solubilize zinc whilst...
