Internship offer at LGP2 - Feb-July 2026 - For several years now, lignin has been attracting growing interest in the field of petroleum-based products, particularly as a partial substitute for bitumen in construction materials. This internship is part of a research and innovation approach dedicated to the development of bio-based binders with properties comparable to those of conventional binders. The objective is to examine and enhance the role of lignin as a major constituent, by deepening our understanding of its physicochemical behaviour and its influence on bio-based formulations.
