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

Biochemical pre-treatments

  • Enzymatic (in vitro)
  • Fungal
  • Microbial
    • Aeration

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
