Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

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 (CSR) in Mining: An Integrated Institutional and Agency Theory Perspective

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 ...

Anaerobic digestion of polyelectrolyte flocculated waste activated sludge [PDF]

Chemosphere, 2003
This work examined how adding one of three polyelectrolyte flocculants (T3052: cationic, T2000: non-ionic, and T1052: anionic) affected the anaerobic digestion of wastewater sludge. Methane production, floc characteristics (morphology and zeta-potential) and process parameters (soluble chemical oxygen demands (SCODs) and reductive potentials) were ...

When Corporations Nudge for Good: Examining the Effectiveness of Corporate Social Marketing Initiatives in Influencing Intention to Change

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

Synergistic Photo‐Electro‐Fenton Oxidation of Antibiotics Using a Ferrocene‐Functionalized MXene (Ti3C2Tx) Electrode

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
2D MXene (Ti3C2Tx)‐based electrode setup for hybrid photo‐electro‐Fenton degradation of antibiotic (tetracycline). The persistence of antibiotics such as tetracycline in aquatic systems poses severe environmental and health risks by potential antimicrobial resistance.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.
