Development of biostimulants from sunflower stalks and heads: optimization of extraction conditions through twin-screw extrusion, bioactivity evaluation, and valorization of extrudate into biosourced materials


Dr. Philippe Evon is a research engineer at the Laboratory of Agro-industrial Chemistry. He is the manager of the Agromat technological transfer hall dedicated to agromaterials in Tarbes near Toulouse, France. He studied organic chemistry in Nantes and Toulouse, where he graduated in 1996 with the Degree of Chemical Engineer (BSc) at the École Nationale Supérieure de Chimie de Toulouse (ENSCT) and later he obtained his Ph.D. in 2008 from the Toulouse University, with a thesis on biorefinery of sunflower whole plant, performed at the Laboratory of Agro-industrial Chemistry, Toulouse. He obtained his habilitation to supervise researches in 2019. Philippe’s scientific interests range from the biorefinery of whole plants to the valorization of wastes from biomass to produce extracts and to design agromaterials. In the last years, he has been engaged in several national and international research initiatives and industrial contracts aimed at using biomass as raw material for:
- producing bioactive extracts through fractionation processes using “green” solvents and the twin-screw extrusion technology as continuous extraction technique.
- the manufacture of agromaterials by combining single- or twin-screw extrusion technologies with molding processes (e.g., injection-molding, hot pressing or 3D printing).
His Ph.D. work has been awarded with the Paul Sabatier Prize (Chemistry section) of the Académie des Sciences, Inscriptions et Belles-Lettres de Toulouse in 2009. He is a member of the French research group on bio-sourced building materials and of the GREEN-CHEM network dedicated to green chemistry.
