Sustainability in the Swedish Macroalgae Industry: Perspectives from Within. A thematic analysis exploring how actors in the Swedish macroalgae food industry perceive and represent ecological, social, and economic dimensions of sustainability

Abstract

This thesis explores how the three dimensions of sustainability –ecological, economic and social– as well as connected possibilities and challenges are represented and understood within the macroalgae food industry in Sweden. Through a thematic analysis of semi-structured interviews and website content from industry actors, the study identifies and analyses five key themes connected to sustainability. The findings highlight an industry rooted in ecological values, cultural interdependence, and market constraints. Additionally, while industry actors understand seaweed as an environmentally beneficial food source and an opportunity to grow, they also face challenges related to low consumer awareness and scalability. The analytical framework draws on Social Metabolic Analysis (SMA) and an interlinked use of Vallance et al's (2011) and Murphy's (2012) social sustainability conceptualisations. The analytical findings emphasise the interconnectedness of the three dimensions of sustainability and give further rise to complexities and nuances within the microalgae food industry. Ultimately, this research contributes with new insights of how sustainability is viewed and practised in this emerging food sector, providing knowledge that can aid industry development and policy-making in Sweden.
