In the bioeconomy, traditional cross-industry barriers will be dismantled, resulting in new forms of cross-sector cooperation. Together with five companies, Cursor has developed a new BioA® concept, a biorefinery integrated into the pulp or paper mill, which produces energy from waste as biogas and/or ethanol, as well as other end products such as fertilisers. The Bio Refine Tech — Bio Refine Tech — Biorefine Tech project, managed by Cursor Oy and implemented by the University of Turku and Aalto University, has focused on researching the suitability of forest industry filters for algae farming and organic fertiliser, while seeking the benefits of biorefinery integration for the forest industry. In addition, the simulation programme commissioned to integrate the BioA concept will model the potential of nutrient cycles in different industrial sectors and the profitability of processing.The importance of the forest industry in Finland has been and will continue to be large, as more than half of Finland’s current bioeconomy is based on forests. The forest industry in south-eastern Finland is the largest of its kind in the world. The development of the forest industry biorefinery business is best achieved if the biorefinery is able to make the best use of all by-products arising from cellulose and paper production: nutrients from waste water and filtration water, as well as carbon dioxide and heat produced by factories and biogas plants. The use of industrial warm filtration water for algae farming improves the profitability of the forest industry. The utilisation of industrial waste water as a nutrient in algae farming also reduces the nutrient content of purified wastewater discharged into a water body and reduces the need for chemicals in waste water treatment. The bioA process laboratory scale expertise acquired during the BioA Refine Tech project is to be extended to pilot-scale testing in this joint project. Each sub-project produces the necessary knowledge and know-how to support each other from the point of view of the whole. The project designs and builds well-functioning equipment by design agencies, equipment manufacturers and Cursor, and creates new business from the BioA concept (Cursor). Based on the Bio Refine tech project, Jamk (Jyväskylä University of Applied Sciences) launches his own algae-breeding piloting in a raft environment. The project is managed by Cursor.The project supports regional bioeconomy priorities and plays a key role in developing Finnish biorefinery expertise. If successful, the BioA concept has great market potential in both developed and developing countries and supports the achievement of Finland’s energy and climate targets. The project will also contribute to the creation of business opportunities and new jobs based on a sustainable bioeconomy.
