Main current biomass technologies are [7]:
1. Destructive carbonization of woody biomass to
charcoal
2. Gasification of biomass to gaseous products
3. Pyrolysis of biomass and solid wastes to liquid, solid
and gaseous products
4. Supercritical fluid extractions of biomass to liquid
products
5. Liquefaction of biomass to liquid products
6. Hydrolysis of biomass to sugars and ethanol
7. Aneorobic digestion of biomass to gaseous products
8. Biomass power for generating electricity by direct
combustion or gasification and
9. pyrolysis
10. Cofiring of biomass with coal
11. Biological conversion of biomass and waste (biogas
production, wastewater treatment)
12. Biomass densification (briquetting, pelleting)
13. Domestic cookstoves and heating appliances of
fuelwood
14. Biomass energy conservation in households and
industry
15. Solar photovoltaic and biomass based rural
electrification
16. Conversion of biomass to a pyrolytic oil (biofuel) for
vehicle fuel
17. Conversion of biomass to methanol and ethanol for
internal combustion engines
