Local stakeholders' cooperation is of primary interest in order to recycle organic residues in agriculture. It is also plausible that environmental burdens occur by such recovering. However in most of environmental assessment methods, actors' perception regarding: What is the environment and What are the environmental consequences to be assessed, are rarely questioned. That may lead to misunderstandings between the actors and scientists, and hinder projects aiming at building such recycling at a territory-level. The aim of our work was to overtake this issue. We conducted an interdisciplinary research that we first present. Then, after describing a case study that is a project aiming at recycling organic residues in agriculture in Reunion island, we base on the framework previously described, in order to express plausible environmental consequences to be assessed. We finally come back to some limits of our work that we put in perspective.
