A framework of disruptive sustainable innovation: an example of the Finnish food system Disruptive innovations are perceived necessary for accelerating sustainability transitions. However, it is not always clear what exactly is meant by it, what is to be disrupted, and by whom. Socio-technical transition research on pays too much attention at the technological niche-innovations in the production, and overlooks business model innovation and user practices in the consumption, whilst management literature on disruptive innovation falls short in the scale and scope of disruption in terms of systemic outcome. Thus, the first aim of the paper is to synthesize the extant literature and put forward a general practice-based view on disruptive sustainable innovation. The second aim of the paper is to use empirical data to elaborate the theoretical framework in the Finnish food system context. Four firm-level cases provide empirical scrutiny to each type of disruptive sustainable innovation in the food system and shed light on the interlinked practices of producer-entrepreneurs and citizen-consumers.

Facing substantial sustainability challenges, sustainable transitions to circular systems are increasingly called for. The use of biomass to produce textile fibers is a niche that could contribute to a circular textile system. In this niche, farmers supplying biomass would play a crucial role. Through a literature review, we argue in this article that farmers are important actors in this context, but their agency is limited by numerous institutional factors, such as cultivation practices, labor markets, and information systems. These factors together can create an institutional void, which can hamper both the agency of farmers and their ability to participate, as well as the justness of the niche. The void’s strength depends on the institutional interface a farmer is subjected to. Before just transitions to circular systems can occur, marginalized actors’ agency and ability to participate in the niche, in a just way, must be improved, by decreasing the strength of the institutional void.

There is an increasing interest in the role of actors in the pursuit of sustainability transitions. In this paper, we adopt a life course perspective to explore active sustainability actors. To this end, we interviewed 16 professionals across private, public, and third sectors in Finland. The paper's main implication is in introducing a life course perspective to the study of active sustainability actors. Second, we propose a grounded model of active actors' sustainability engagement. The model details sustainability agency formation and maintenance dynamics. Going forward, our findings are a call for further research on sustainability agency, be it in its engagement, via life courses, or via the study of different actor types.

Although corporate sustainability has gained more attention and companies have recently showed a growing interest in sustainable practices, the progress towards sustainable development has been slow leading to increasing environmental and social challenges. . Business model innovations are recognized as a key to the creation of sustainable business and as a bridge between company level and system level changes. Sustainable business model innovations create, deliver and capture economic, social, and ecological value for customers and other stakeholders in various societies.The aim of this article is to deepen the understanding of the ways how companies create and capture sustainable value through business models in a larger operation system. From the theoretical perspective, the article adopts the transition theory and the concept of strong sustainability for understanding socio-technical transitions and business model changes towards sustainability. Here the focus is on companies' dualistic role pursuing sustainable development targets -both contributing to sustainability within the business dimensions, and assisting the broader systemic change through the new sustainable business models. Furthermore, the article deals with the external factors that either enable or hinder companies to transform their existing business models towards sustainability.By reviewing previous literature, this study develops preliminary frameworks combining the approaches of transition management, sustainable value creation and corporate sustainability levels. The work aims to decrease the existing gap between the literature of system transition and business models. The frameworks can be applied in the future in analyzing new sustainable business models, value processes, value creation and capture, and broader systemic changes towards sustainability.
