The current state of the agri-food systems calls for more attention to sustainability. This article explores how diverse business models can contribute to sustainability in food systems, and develops a new business model typology in this domain in which the wider business ecosystem is taken into account. A systematic literature review is done and 37 articles are analyzed according to the business model types, their various sustainability dimensions and roles within the food system. Nine different business model types for sustainable food systems are identified: circular business models, place-based social food networks, new logistics or online food distribution business models, disruptive, sufficiency, inclusive, and family business models, the focal company, and regional food hubs. Collaborative approaches, clear sustainability visions, companies' values and continuous innovation are important factors for agri-food business models striving for sustainability. More in-depth single-country but also cross-country comparative and cross-disciplinary research is needed for understanding business models and their transitions toward sustainable outcomes within diverse and complex food systems.
