INRA’s laboratory BIA (Biopolymers Interactions Assemblages) is conducting research on the sustainability of agri-food and the rational development of agricultural resources. Thanks to Operation TRADER “Sustainable Approach to the Transformation of Agro-Resources”, the BIA laboratory aims to gain a better understanding of the entire processing chain of agro-resources from construction to deconstruction during final use. Registered at the CPER 2015-2020 for an overall investment of EUR 4 million, TRADER is composed of several components. This grant application covers the first last phase of the TRADER equipment acquisition and concerns the components “Support to multi-scale analysis tools of the BIBS platform” and “Power-mounted on lipidoreactomic and biopolymer interactions for functional assemblies”.
