Dutch riverine areas are managed intensively to ensure the provision of various ecosystem services. Vegetation management, including pruning and mowing, produces a woody and grassy biomass as a by-product. In the past, this residual biomass has been treated as a waste product. Now there is a change of perspective; biomass is valued as a potential additional ecosystem service instead of a waste product. In this study, we explore the transition from waste to ecosystem service of residual biomass in Dutch water management organisations. We found several trends in the organisation of biomass use. There is a development away from the traditional approach of choosing the cheapest or easiest way to get rid of biomass towards exploring various uses of biomass that fulfil additional, societally relevant, functions. This trend alters the organisation of vegetation management and subsequent biomass use. Selection based on sustainable biomass uses is gaining importance, and there is a growing desire within public organisations to be able to steer towards sustainable use of residual biomass. However, there is a lack of applicable, objective ranking instruments.
