In the field of procurement, STAREG is particularly interested in obtaining materials that make up the entire product unit before the production phase, as its final objective is to create a vertically-integrated product. Indeed, the delivery of materials into production is a major problem of circularity we want to adress. Material supplies are predominantly virgin sources in a linear economic model. It is problematic because it is costly and causes waste and other negative externalities at the end of the value chain. Material design, therefore, shall take into account the product's circularity potential.
