Recycling is a complex activity with long, sometimes unknown and not easily implemented processes. It requires diverse technologies from many fields of application. This sector is marked, on the one hand, by a lack of data, information and knowledge structuring, and a deficiency in management tools and in the sharing of this knowledge, on the other hand. These actors do not have the same understanding of the product, and are facing difficulties to take decisions for an optimal recycling.

This paper suggests a system of information for decision-making assistance for an optimal recycling, applied to the sector of aeronautics for example. In so doing, we first establish a referential product model for recycling, to be used for the conception, utilization and recycling, and then the same model will be integrated in a team work structure. This structure allows a more fruitful collaboration between actors, with the eventual integrating of sundry viewpoints.

This analysis offers a system of information for decision-making assistance for recycling, based on the product. The theory of the decision used in this study will help to optimize the recycling of the product, through an optimal choice of the actions to conduct.
