C6 fermentation produces three separate renewable energy and revenue streams and
has been licensed since 2010. C6 fermentation has been optimised through 15,000
hours of production since 2009.
C6 fermentation is the original concept of the Inbicon Biomass Refinery, proven
and optimised at Kalundborg since 2009 with 15,000 hours of production. This
includes upgrades in equipment design for greater efficiency and lower operating
C6 fermentation converts the biomass into three green energy streams - ethanol
based on C6 fermentation, C5 molasses for livestock feed or biogas production
and lignin to be used as e.g. solid biofuel for heat and power production.
C6 fermentation is a strong choice for projects located in countries with
high demand for livestock feed and/or high renewable power prices as lignin and
C5 molasses gives several options to complement revenue from ethanol.
Because the C5 molasses reacts in the anaerobic digestion of manure it can
enhance power production from existing biogas facilities significantly. With
DONG Energy's experience in biogas production and heat and power production,
this can be a highly valuable product.
C6 fermentation is currently the centrepiece of integrated Inbicon projects in
China and US. The C5 molasses and lignin are used for biogas and green power
generation, which can drive the process; excess power can be sold to the grid.
