For projects to contribute to sustainability transitions, traditional roles of project actors need to be challenged. This paper focus on the changing role of demolishers in circular construction projects. We explore the role changes needed and the tactics adopted to negotiate these changes. Therefore, we collected data across 10 demolishers and two construction projects in the Netherlands. We identified required changes related to task, timing, position, and image. The studied demolishers adopted six different tactics to negotiate these changes. These findings contribute to the sustainability transitions literature by highlighting the important function of projects in operationalizing role changes and enabling change in the roles of incumbent actors. Furthermore, the results contribute to the debate on roles in sustainable projects, and on the roles of demolishers in particular, showing the different elements and non-linear nature of role change, including the unique challenges and tactics adopted by demolishers to negotiate these changes.

Transferring knowledge across strategic projects is challenging. This study investigates how informal practices of members of the parent organization shape the transfer of knowledge across strategic projects. This was addressed through an in-depth case study of strategic projects in an innovation trajectory of a large public organization aiming to accelerate to transition towards circular construction. We identified five disabling practices: shaming and blaming, disconnecting, holding onto the department and project boundaries, fostering one-way relationships and avoiding internal conflict. Furthermore, we identified three enabling practices: supporting circular projects, sharing similarities across projects and integral visioning. The results contribute to the cross-project knowledge transfer literature by showing how members of partner organizations can enable or disable knowledge transfer across strategic projects. Furthermore, the results contribute to the strategic project literature by illuminating the importance of informal practices of members of the parent organization.

This paper addresses the lack of attention for the behaviours and agency of actors in organizations in the sustainability transitions literature by focussing on practices of inter-organizational collaboration in the transition to circular construction. Practices of inter-organizational collaboration can slow down this transition and are deeply embedded in the construction regime, creating critical points of intersection. This research therefore investigated how reflective interventions can enable project actors to change their practices and support the transformation of critical points of intersection into points of opportunity in circular construction. To answer this question, we adopted a case study approach with action research elements. The results of this study contribute to the sustainability transitions literature by showing how reflective interventions can assist in the transformation of critical points of intersection through five processes, including prioritising reflection on practices, critically evaluating practices, creating a breeding ground for new practices, implementing new practices and embedding new practices in partner organizations. Furthermore, we move away from the focus on policy interventions and offer more room for the agency of actors in projects, by showing how reflective interventions can create experimental environments close to the day-to-day activities of project actors enabling them to simultaneously unlearn obsolete practices and learn new practices.

The fields of sustainability and entrepreneurship share their dynamic processes, their high degree of uncertainty and complexity, and their endeavor on systemic impact. These inherent characteristics call researchers to engage in action research. Action research equips researchers with unique tools to navigate the volatility and complexity of sustainable entrepreneurship while simultaneously fostering its purpose and uncovering new theoretical insights. Yet, action research efforts fostering sustainable entrepreneurship are still emergent, and the mutual affinity between sustainable entrepreneurship and action research is still seldom addressed in the literature and often confused with other forms of collaborative knowledge production and problem-solving such as co-creation and consulting. In this chapter, we discuss the central principles of this form of academic knowledge production, their practices, and implications for sustainable entrepreneurship. We begin by defining action research and its unique methodological features. We then highlight research practices to address two fundamental but overlooked aspects of action research: value reciprocity and impact temporality. We illustrate these aspects by providing two cases of action research in a sustainable entrepreneurship context. This chapter offers directions for the researcher embarking into action research journeys aimed at fostering sustainable entrepreneurship.@en

Innovation contests are increasingly used by businesses as an instrument for open innovation to address sustainability related questions. However, according to the open innovation literature, one of the main pitfalls of this approach can be the mismatch between the solutions proposed by non-experts and the companies’ capabilities to implement such solutions. We introduce the concept of collaborative innovation contests – where companies actively collaborate with non-experts – as a way to address this mismatch. Through participant observations, we analyse the process of a sustainability-oriented collaborative innovation contest guided by design-thinking. Our results indicated that the combination of an open innovation contest and design thinking could, through the creation of constant feedback loops, lead to increased collaboration between the contests participants, the companies proposing a challenge, and other relevant stakeholders. However, our results also highlighted trade-offs between the innovativeness of ideas, the alignment of solutions with firm capabilities and the resources needed for collaborative innovation contests. We conclude that, through the involvement of different stakeholders, their ideas and perspectives, collaborative innovation contests are a useful approach to generate a comprehensive understanding of the sustainability challenges companies face.@en
