Can algae replace commodities of today? • European market: • Fossil fuels: 400 Mtonnes/year • Polymers and chemicals: 100 Mtonnes/year • Palm oil: 7 Mtonnes/year • Soy: 8 Mtonnes/year • Global microalgae market today: • < 10,000 tonnes/year
Develop this process is a sustainable and economical way within the next 10 -15 years To develop a more sustainable and economically feasible process, all biomass components should be used
From basic toapplied research • Resources • Efficientuse of sunlight • Reduction of energy input • Use of residualnutrients • Strains • Lipidaccumulation • Metabolic Engineering • Implementation • Scale-up • Biorefinery • Design scenarios/LCA’s
Antennasizemutants • Wild type cells • Cellsoversaturated: heat dissipation • Antennasizemutants • Light-saturation at higher light intensity • Less energy wasted. Tim de Mooij Turbidostat
Behaviourduringday/nightcycles Lenneke de Winter • The aim of this research is toobtain more knowledge in the circadianbehaviour of the cellcycle of lipidproducingmicroalgaegrown in photobioreactors. Thiswillprovidewaystooptimize the currentproductionprocessunder outdoor day/nightcycles. • Neochlorisoleoabundans is grown in a lab-scalephotobioreactorundersimulated outdoor conditions. • The circadianrhythm of the cellcycle is analysedusing flow cytometry. • In addition, cellcomposition (lipids, starch, proteins) during the cellcycle is investigated.

AlgaePARC • Basic research is not sufficient • Gap between basic research and commercial applications • Continuous interaction between basic research and pilots • Follow up in demonstrations • Products • Scale • Production chain
AlgaePARC • International centre of applied research • Intermediate between basic research and applications • Development of competitive technology (economics, sustainability) • Acquire information for full scale plants • Algal biomass for food, feed, chemicals and fuels
Scenario: Lipids + Biogas energy Scenedesmus: €600/T Cost of production: €500/T
Scenario: Lipid & protein biorefinery Nannochloropsis: €8,000/T Cost of production: €500/T
AlgaePARC biorefinery • Fractionateallcomponents • Maintaintheirfunctionality • At low energy input
EU-FP7 projects • INTESUSAL: demonstration project Portugal • ALGADISK: biofilmreactor; pilot Spain • FUEL4ME: biofuel project with pilots in Israël, Italy, Spain and Netherlands • SPLASH: biomaterials project with pilots in Spain and Netherlands • MIRACLES: biorefinery project for food and feed applicationswith pilots in Norway, Chile, Netherlands and Spain
Education • Primary school • High schools • Design challengeand practical kit • BSc • Physiologyandprocess design • MSc • Bioreactor design • PhD • Designing of microalgae-basedproductionprocesses, for research and commercial purposes • Next edition: June 2014
Algae for commodities • Demonstrate that biobased products have the quality to replace existing products • Convince we can produce economically in the future • Imagine we can reach the right market volumes • Create awareness: it is not going to be easy • Join forces • Create a long term commitment
