Processes
Future biorefineries require cost-effective and efficient process technologies for the separation of compounds from process streams that can be refined into valuable biomass-based chemicals or fuels. Innventia has world-leading competence in this field, and can offer consulting work where different processes are studied either in our well-equipped FracLab or directly on location at mill sites.
 
Examples:
  • The patented LignoBoost process for the extraction of lignin from black liquor
  • High-temperature membrane separation of e.g. hemicelluloses from process liquids
  • Leaching of inorganic and/or organic compounds from wood chips.
  • Separation of suberin and betulin from hardwood bark with a water-based method (patent pending).

To give the whole picture, aspects on energy, further processing into chemicals and materials and mill system aspects can also be investigated.
