10 Macro Algae Biorefinery A Danish funded project. Start 2012 Budget 24 million DKK The Hypothesis in the project are: 1) Two brown macroalgae (Saccarina latissima and Laminaria digitata) can be upgraded to energy carriers (either bioethanol, buthanol or biogas) by conversion of 80% of the fermentable sugars, leaving behind a concentrated solid fraction rich in protein and lipids, which can be used for fish feed. 2) A substantial amount (90%) of the remaining, undigested sugars i.e. the C5 sugars can be converted to additional value-added amino acids (isoleucine and arginine) for fish feed supplement.

11 Danish Seaweed Network Aim: The Seaweed Network in Denmark aims to promote the production, application, communication and knowledge of seaweed, and also strengthen the national collaboration Tang som food og non-food Invitation til tangnetværksmøde mandag d. 23. marts kl. 16 DTU Aqua Søltoft plads bygning 221, lokale 237 (2. sal) 2800 Kgs.

12 Natural Ingredients and Green Energy Innovation consortium: UpFront Chromatography Aquaporin DSS Silkeborg Agro Korn CEBI Launis Fiskekonserves Jens Møller Products Aller Aqua University of Southern Denmark Technical University of Denmark Aarhus University Danish Technological Institute Overveiw: 1) High value products (proteins, antioxidants, pigments) can be extracted from waste products and algae using sustainable extraction processes Red algae pigments effects of light and nutrients 2) Residues can be used for anaerobic digestion to biogas or combustion

13 BioWalk4Biofuel EU FP7: Italy Jordan India Sweden Holland Latvia Spain Denmark (Aarhus University Danish Technological Institute) Overview: 1) Bio waste products with high nitrogen content will be used for cultivation of algae 2) Algae and bio waste will be used for production of biogas 3) Residues from biogas production will be used for soil improvement 4) Biogas will be upgraded to Liquid Biogas (LBG)

14 The Ulva lactuca project Production potential of Ulva Growth of Ulva in basins Effect of CO2 / flue gas from Power Plants to boost the growth Energy potential of Ulva Physical and chemical characterisation of Ulva Pretreatement for fermentation, combustion and gasification Bioethanol /Butanol production Biogas production Biofuel for Power Plants corrosion, emissions, waste water, flue gas cleaning, ash products Recommandations for Ulva production in basins at Power Plants Financial evaluation of Ulva for energy purpose

15 Overall conclusions of the Ulva project 1. Annual yield is 4-5 times land based energy crops. 2. Potential for increased yield when bubbling with flue gas. 3. Ethanol / butanol can be produced from pretreated Ulva of C6 and - for butanol - also C5 sugars. Fermentation inhibitors are easily removed by screw pressing. 4. Methane yields of Ulva is at a level between cow manure and energy crops. 5. Thermal conversion of Ulva is possible with special equipment 6. Co-firing of Ulva with coal in power plants is limited due to high ash content. 7. Production of Ulva only for energy purpose at power plants is too costly 8. N2O emission has been observed in lab scale, but not in pilot scale production.

17 20th European Biomass Conference in Milano abstracts evaluated on micro and macro algae. Total no. of abstracts From this R&D From this DEMO From this LCA Macro algae Micro algae

18 21st European Biomass Conference Copenhagen June 2013 I recommend you to send in abstracts on algae projects. Topic 1.5: Algae production systems Topic 2.7: Biorefineries Topic 5.2: Sustainability assessment and criteria DEADLINE FOR ABSTRACTS IS: 21. January 2013

19 Future perspectives for algae 1. Large scale production of micro algae is still a challenge 2. Large scale production of macro algae must be off-shore. 3. A biorefinery concept is needed to extract high value products as proteins, food & feed ingredients, materials etc. before end use for energy. 4. Macro algae is the new biomass ressource for the next decades. 5. Micro algae is an important raw material for high value products
