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

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Mining is one of the foundations of economic development but has historically been associated with severe socioenvironmental impacts, such as ecosystem degradation, displacement of traditional communities, and large‐scale disasters. In this context, corporate social responsibility (CSR) plays a central role as a mechanism for legitimizing ...

CONDITIONING PROCESS AND CHARACTERIZATION OF FRESH ACTIVATED SLUDGE [PDF]
Journal of Engineering Science and Technology, 2015 Fresh activated sludge in many wastewater treatment plants may be considered unhealthy due to the large amount of organic and organism content. Due to the lack of research on municipal sludge, there is an apparent scarcity of actual data. Thus, this work

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Firms invest heavily in corporate social initiatives (CSIs), yet evidence of behaviour change remains limited. This study examines whether corporate social marketing (CSM) elicits stronger behavioural intentions to change than other CSI formats, such as philanthropy and cause‐related marketing (CRM), and identifies the psychological mechanisms

Influence of copper nanoparticles on the physical-chemical properties of activated sludge.
PLoS ONE, 2014 The physical-chemical properties of activated sludge, such as flocculating ability, hydrophobicity, surface charge, settleability, dewaterability and bacteria extracellular polymer substances (EPS), play vital roles in the normal operation of wastewater ...

Stability and performance of two GSBR operated in alternating anoxic/aerobic or anaerobic/aerobic conditions for nutrient removal [PDF]
, 2012 Two granular sludge sequencing batch reactors (GSBR) with alternating anoxic/aerobic (R1) and anaerobic/aerobic (R2) conditions were operated with a 4-carbon-source synthetic influent. The physical properties of the granular sludge were very good (SVI≈20
