THE CULTIVATION OF MICRO ALGAE AT PAPER MILLS PROVIDE BIO-OIL

Next to Nordic Paper in Bäckhammar there is a pilot plant that cultivate microalgae using waste products from the mill. This specific algae is perfect for producing bio-oil. This Algae cultivation pilot plant is part of a three year project which you can read all about on this page.

The project started in 2013 and will be completed in 2015. The aim is to develop a process that effectively allows the algae to take care of the nutrients in the mills’ waste water and to sequester carbon dioxide from the flue gases. A bio-oil can be extracted from the algae. The oil can be refined into many products, such as biodiesel, bioplastics and lubricating oils. The utilisation of waste heat provides us with an optimum growing temperature.

This project has the potential to provide benefits to the environment and to create new business opportunities for the mills. During the first project period, it focuses on the pulp and paper industry, but in the long term, other industries and uses will become relevant.

Behind the project is the SP Technical Research Institute, Paper Province, Nordic Paper Bäckhammar and eleven other stakeholders from industry, academia and the public. The total budget is just over eight million SEK, of which Vinnova has financed four million SEK.

MASTER THESIS

The pilot plant has also attracted students in the area. Several degree projects related to algae cultivation in Bäckhammar have been written. Sara Jonasson, Amanda Larsson and Matilda Schollin, students at The University of Karlstad’s Bachelor programs of environmental and energy technologies, accounting for three of them. Amanda for instance, have digested the algae to investigate their biogas potential. Sara have conducted a system analysis of nutrients for micro algae cultivation, while Matilda has looked into the possibility of regulating the pilot plants temperature using solar reflection and a heat exchanger. Mikael Svensson at The University of Chalmers has based its study on algae cultivation in Bäckhammar. He examined the feasibility of using the mill bio-sludge as food source for growing algae.
