| Abstract | In recent years, algae production has attracted increasing scientific interest, mostly because of potential high biomass yields for production of lipids, protein and chemicals. For large-scale production of algae, large amounts of nutrients are needed. Replacing commonly used artificial fertilisers with recycled or alternative sources of nutrients is highly important, both for lowering algae production costs and for displacement of phosphate rock mining. This study evaluated the possibility of producing algae biomass in an economically viable way using digestate as a source of nutrients and by combining the cultivation of algae with a codigester and CHP unit for usage of flue gass and residual heath. A short literature review is made and results from a pilot plant and a small scale expeiment in the Netherlands are given. Several algae species can grow on diluted digestate. Combining algae cultivation with codigestion profits if algae are sold as feed additive. Renewed regulations ask a risk analyses and additional analyses to allow the algae produced to be sold as feed. |
