This is the belief of The Energy Square in Karlstad and Nordic Paper Bäckhammar. They are doing a feasibility study on how micro-algae can be used to make bio fuels using mill bi-products. The pilot study is being led by the SP Technical Research Institute and is financed with about 750,000 Kronor from Vinnova.“This is a very exciting project, where we link together different parties. In time, the project will hopefully contribute to increased profitability at the mills, as waste products are converted into a resource. It is also good for the environment,” says Magnus Persson, Head of The Energy Square.Algae takes care of the nutrients in the waste water from the mill and captures carbon dioxide from flue gases. Oil can then be extracted from the algae, and what’s left can, for example, be digested into biogas or pelleted. The process will reduce eutrophication and carbon emissions and create new revenue streams for mills.The feasibility study will show how the process might look and identify potential partners along the entire chain, from plant to end users. If the feasibility study shows that the process is feasible, pilot studies will be made at Bäckhammar mill.
