Goals

course
To apply the main mechanisms of organic chemistry to the chemistry of the major constituents of plant biomass (cellulose, hemicellulose, lignin)
To act for sustainability and to make innovation

Learning outcomes :

  • To know the chemical and physical structure of the lignocellulosic biomass components
  • To explain lignocellulosic component reactions in conventionnal industrial transformation processes and in aggressives media
  • To identify the valorisation routes of lignocellulosic components
