An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Does Stakeholder Pressure Promote Green Innovations and Performance of Agribusiness Companies?

Business Strategy and the Environment, EarlyView.
ABSTRACT The sustainability of agribusiness companies is guided by multiple, sometimes paradoxical, interests. Green innovation is strategic for sustainable development; however, literature shows inconsistencies regarding its impact on environmental and economic‐financial performance.

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Analysis of the physical and mechanical properties of coal-based solid waste filling material at early ages

Frontiers in Materials
Fly ash-based filling materials are widely used in coal mine backfilling due to their cost-effectiveness and environmental benefits, but their application is often hindered by low early-age strength, poor fluidity, and severe water segregation. This study aims to enhance the performance of such materials by examining the effects of varying water-to ...
