Biogas production from Spent Bleaching Earth and Alkaline Fish Glycerin

The purpose of the present study was to examine the biogas potential from anaerobic digestion of alkaline fish glycerin (AFG) and spent bleaching earth (SBE) from omega-3 fish oil refining. Both fractions show promising use in biogas production feedstock. However literature review on SBE from fish oil refining was limited to one publication. Publication with AFG did not exist at our knowledge but a publications on a similar product, crude glycerin from biodiesel production, seems to be more developed.
