In this paper we discuss how we can contribute to research and practice in what is known as industrial symbiosis by developing the concept symbiosis governance that aims at exploring sustainability and digital solutions in public sector. We focus on digitalization in Swedish municipalities, specifically on how digital services known as part of the sharing economy can be harnessed for fulfilling obligations and deliver welfare services to residents. The paper takes a controversy around the digital application TippTapp in Stockholm municipality as a starting point since it highlights how innovative ways of organizing everyday activities, like waste management, with digital solutions can be objected (and even deemed illegitimate) in a Swedish municipality. This paper engages with three areas of application where we will work in a research project: school buses, home care and waste management that are core activities in Swedish municipalities and where digital innovations possibly can be used. The discussion is done in relation to the policy expressed by the Swedish government that Sweden should become best in the world at harnessing the possibilities of digitalization, and how this can be done at municipal levels, particularly as previous research has shown that local leaders and politicians are grappling with digitalization and tend to express rather low digital maturity. The paper is based on a conceptual discussion about digital solutions in public sector.
