Advancing Theory and Practice Concerning CO2e Emissions: A Time‐Based Tool for Organisations

Business Strategy and the Environment, EarlyView.
ABSTRACT Although organisations are increasingly scrutinised on their CO2e emissions, economic growth is frequently encouraged. Eco‐efficiency–based initiatives—‘doing more with less’—could be a solution. The problem is that many organisations (e.g., smaller enterprises without access to specialist knowledge) have difficulties in gauging the impact of ...

Defining Remanufacturing: A Key Business Strategy Advancing Industrial Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT Remanufacturing is a key strategy in the circular economy, enabling substantial product value retention. However, inconsistent definitions across standards and legislation hinder global trade, core recovery and market acceptance. This study examines how remanufacturing is defined in laws and standards, and how these definitions impact industry

N- and O- ligand doped mesoporous silica-chitosan hybrid beads for the efficient, sustainable and selective recovery of rare earth elements (REE) from acid mine drainage (AMD): Understanding the significance of physical modification and conditioning of the polymer.

Journal of Hazardous Materials, 2018
Silica-chitosan hybrid beads were synthesized via three different methods to investigate the selective recovery of REE from AMD. The influence of amino/non-amino silanes, high molecular weight/high viscous chitosan and N-/O- based ligands were studied ...

Structural Constraints to Sustainable Supply Chain Diversification: Rare Earth Elements, Business Strategy and Resilience in the Energy Transition

Business Strategy and the Environment, EarlyView.
ABSTRACT Rare earth elements (REEs) are critical inputs for low‐carbon technologies, yet their supply chains remain highly concentrated and vulnerable. Although diversification is widely promoted as a strategy to enhance supply chain resilience, its feasibility in strategic material systems remains limited.
