DSM enzymes for cellulosic ethanol qualified by DONG Energy
(Thomson Reuters ONE) -
Royal DSM, the global Life Sciences and Materials Sciences company, has been
qualified as supplier of enzymes for DONG Energy - Inbicon's wheat straw to
cellulosic ethanol process. The enzymes have been successfully used in the
demonstration scale biorefinery of DONG Energy - Inbicon in Kalundborg, Denmark.
The qualification reconfirms the high standard and flexibility of DSM's cocktail
of enzymes to break down and convert the cellulose and hemicellulose from the
straw fibers into simple C5 and C6 sugars. DONG Energy - Inbicon Biomass
Refinery is the world's largest scale cellulosic ethanol demonstration plant
that is currently in operation. The plant has a capacity of 1.5 million gallons
a year and produces cellulosic biofuel for Statoil which is distributed via
gasoline stations throughout Denmark.
DSM's enzyme cocktail is particularly effective at breaking down cellulosic
biomass to component sugars while having a very high thermal stability. Because
of this the hydrolysis step can be performed at higher temperatures, while
decreasing the risk of product loss. Higher operating temperatures also increase
process speed and ultimately lead to a reduction of the amount of enzyme needed.
DSM's enzymes have been proven in multiple tests at various scales by research
institutes and company labs across the globe to be working across multiple
feedstocks, including corn crop residue, wheat straw, wood chips and sugarcane
bagasse. They have also been tested on the full range of pre-treatment, from
very harsh to relatively mild (as is the case in the Inbicon process), giving
supportive evidence to the versatility of the DSM enzyme system. The break down
or pre-treatment of crop residue is the first phase of the conversion process
towards cellulosic bio-ethanol.
DSM selected its enzymes using the biomass as the starting point for the
selection process. These are substrates that are expected to be commercially
leading in future production of cellulosic bio-ethanol.
Jan Larsen, head of R&D Inbicon, says: "The DSM enzyme cocktail has performed
successfully in the Inbicon process at demonstration scale. It showed the same
high yield as was obtained in pilot scale. This cocktail has both a broad pH
range and high temperature tolerance which make DSM's enzymes very favorable for
industrial production of cellulosic bio-ethanol at high dry matters. The
technical reports and analysis from the test program are now finalized and we
conclude that the DSM enzymes are now qualified for the Inbicon process"
Stephan Tanda, member of the DSM Managing Board, comments: "We are proud to
receive Inbicon's endorsement of our enzymes technology. This additional
qualification strengthens DSM's global enzyme position and confirms our drive to
being a technology partner for cellulosic bio-ethanol producing companies across
the globe. DSM offers the broadest technology currently available in the market,
with high performing enzymes and yeasts that are able to convert a large variety
of biomass into cellulosic ethanol."
