Business Strategy and the Environment, EarlyView.ABSTRACT The circular economy, dominated by capitalocentric, technocentric, and eco‐modernist discourses, risks perpetuating systemic injustice because of its limited consideration of the social and of what is possible. In this article, we examine how social justice can be embedded into circular business models (CBMs)—key drivers of the circular ...

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
