Biomass to Biofuels ?
Renewable
? Low H/C ratio
? Contains water
─ Corrosion problems
? High oxygen content
(aldehydes, acids, cetones)
─ Reduced heating value
─ Reduced oxidation stability
─ Increased acidity
Biomass requires H/C increase, oxygen and Η2Ο removal
Engine performance problems

Achievements & Potential
 Optimal exploitation methodology of waste oils
 Avoid problematic disposal, 100% conversion to biofuels (Biodiesel-2G,
heavy fuel)
 Technology of producing highly-sustainable-high-quality
renewable diesel based on waste oils and RES
 More economic, more reliable, no engine adjustments/changes required
 Potential for meeting 9,5% of Greek diesel demand
 ~223.000 tons or 282.195 m3 Biodiesel-2G
 CO2 emissions improvement 14.4-15% (WTW) over conventional
market diesel
 Technology expanded for integrating waste oils in underling
refinery infrastructure (hybrid diesel / Hellenic Petroleum)
