The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Food Chemistry International, EarlyView.ABSTRACT The growing global demand for sustainable, nutritionally balanced protein sources has intensified interest in plant‐derived proteins, particularly those derived from oilseeds such as groundnut (Arachis hypogaea L.). However, although groundnut protein isolates (GPIs) have high nutritional quality, they exhibit limitations in technofunctional ...

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...
