The project aimed fostering the use of forestry side-streams as economically and ecologically sustainable raw material of bioactive compounds for the development of different products. The project tested and innovated treatment techniques through which the high-added-value
compounds of forest trees can be tailored to meet end-use requirements. Research utilisation was be conducted in a close collaboration with SME's in Lapland. In the project, stilbenes and tannins were extracted from the bark side-streams by using environmentally friendly techniques. The research results indicate that e.g., tannins can be used as aroma- and preservation ingredients in foodstuffs. Light reactions of stilbenes lead to the formation of more antimicrobial and antioxidant extracts. Drying methods had an effect on raw material quality of spruce sprouts. Maximal utilization of bark was piloted by studying the combining of the processes of hot water extraction, pyrolysis, and anaerobic digestion (AD).
