Abstract. The Maker movement represents a return of interest to the physical side of digital innovation. To explore expectations and values within the Maker movement, we applied qualitative research method, interviewing 10 managers of maker initiative as well as 39 makers from eight different countries. The paper analyses how the Maker movement is contributing to a change in production, logistics and supply chains and how it changes the relationship between producer and consumer. Based on the interview data and supported by literature, the study indicates that the Maker movement has the potential to impact producer-consumer relationships in many ways. Making, on a bigger scale would mean producing locally, de-centralised and on-demand. This would have an impact on the logistics and the supply chain. Long transportation routes would be avoided and shorter supply chains would make some of the-inbetween vendors obsolete. Makers as prosumers, who produce for themselves, are introducing two growing phenomena: a more personalised relationship between maker and object and personalised products as a form of self-expression.

Microalgae are an evolving field to produce sustainable nutritious food with low environmental impact. To shape the emerging European value chain in a sustainable way, all actors and processes need to be considered. This article builds on the results of multi-stakeholder scenario workshops organised within the EC-H2020-funded project ProFuture. It investigates the roles different actors along the microalgae value chain hold to shape it. A qualitative analysis identified three actor groups: (1) microalgae producers and processors, and researchers who work with microalgae and their development, (2) policy makers, and large industrial players, who influence the political and economic possibilities of the microalgae value chain and (3) consumers, who play a key role in order to root sustainable microalgae food products in the market. The paper shows how these groups interlink and draws conclusions about their roles for shaping the European microalgae value chain.
