Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

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

open access: yesCorporate 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 ...

Biologically induced phosphorus precipitation in aerobic granular sludge process [PDF]

open access: yes, 2011
Aerobic granular sludge is a promising process for nutrient removal in wastewater treatment. In this work, for the first time, biologically induced precipitation of phosphorus as hydroxyl-apatite (Ca5(PO4)3(OH)) in the core of granules is demonstrated by

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

open access: yesCorporate 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
