From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

African Twist of Circular Economy: Insights, Policies and Recommendations

Business Strategy and the Environment, EarlyView.
ABSTRACT While the circular economy (CE) has gained traction, this paper argues that mainstream CE approaches risk being misaligned in the African context. Drawing on a mixed‐methods synthesis of empirical studies, policy documents and cross‐country examples, the study shows that Africa's CE transition is fragmented and uneven, leaving the continent at

An Integrated Three‐Phase Green Quality Function Deployment Framework for Evaluating Lean–Green Criteria Under Uncertainty

Business Strategy and the Environment, EarlyView.
ABSTRACT Manufacturers need decision models that translate environmental and customer requirements into operational priorities while integrating lean and green practices within a unified programme. This study develops and applies an integrated decision framework to identify, structure and prioritise lean–green manufacturing criteria and to examine how ...

Optimization of moisture content and application rate of hay preservative during high‐moisture alfalfa hay baling in northwestern China

Grassland Research, EarlyView.
Abstract Background Leaf shatter during low‐moisture baling and mold proliferation under high‐moisture conditions pose major challenges in alfalfa hay production. A proprietary propionic acid‐based hay preservative product, LZP, effectively inhibits microbial reproduction in high‐moisture alfalfa bales; however, its optimal moisture thresholds and ...
