Pre-treatment technologies are used to prepare raw materials so that they can be processed by core technologies.

Biochemical pre-treatments

Chemical pre-treatments

Physical pre-treatments

  • Densification
  • Microwave
  • Pressure-densification
  • Sizing
    • Chipping
    • Grinding
  • Steam explosion
    • Air
    • Supercritical CO2
  • Thermal expansion
  • Ultrasonication

Separation pre-treatments

Thermochemical pre-treatments

  • Ammonia fibre expansion
  • Dry torrefaction
  • Wet torrefaction

Pulping (we need to divide all pulping subcatecories to the existing ones, suggestions are welcome)

  • Chemical pulping
    • Organosolv
    • Soda
    • Sulphate
    • Sulphite
  • Hybrid pulping
    • Neutral Sulfite Semi Chemical pulping (NSSC)
    • Chemithermomechanical pulping (CTMP)
  • Mechanical pulping
    • Refiner
      • Thermomechanical pulping (TMP)
      • Refiner mechanical pulping (RMP)
    • Groundwood
      • Stone groundwood (SGW)
      • Thermal groundwood (TGW)
      • Pressure groundwood (PGW)
