How to sustain algae industries?
Improving simultaneously strains, cultivation, harvesting and
conversion processes is a key success factor

Time
• Low-volume / high-value added markets are a starting point = today’s algae industry
• Biorefineries and biobased chemistry are a societal expectation and an opportunity to
bridge the gap towards biofuels
• Synergies have to be found with environmental services, taking advantage of the
bioremediation potential and wide applicability of algal biomass

Strategic focusses
Integrate solar-power options
Innovative approaches for integrated
at every process step
protection of algal crops
(cultivation/harvesting/drying/conversion)
(algal microbiomes)
Develop synergies between environmental processes
and production of algal biomass :
 Bioremediation of aqueous wastes
 Capture & Reuse of CO , NOx & SOx

Connect to biorefinery schemes, in
relation with new opportunities
in the biobased economy Sustain developments in HTL
and catalytic upgrading
to liquid diesel and jetfuels
