This work made use of the RawMatTERS Finland infrastructure (RAMI) facilities based at Aalto University. This work was a part of the Academy of Finland's Flagship Programme under Projects No. 318890 and No. 318891 (Competence Centre for Materials Bioeconomy, FinnCERES). Industrial support and advising is gratefully acknowledged to Dr. Kemppainen Katariina from Metsä Spring Oy and Dr. Suurnakki Anna from Metsä Fibre Oy. From Aalto University, Dr. Heidi Henrickson provided English-language proofreading. Dr. Leena Pitkänen provided the assistance for the molecular weight analysis using GPC. Appreciation is also extended to team SBARK (Megan McGlynn, Chiao-wen Hsu, Iines Jakovlev, Eveliina Juuri, Nina Riutta, Aarni Tujula), Prof. Pirjo Kääriäinen, and Eeva Suorlahti from Aalto University CHEMARTS for providing high quality photographs of spruce tree. Liu Zhongqi from Westlake University assisted with image visualization.

N2 - Wood bark has exclusively been used for energy at pulp mills, while long-neglected, this huge biomass resource has great potential for valorization. To maximize its value in new ways, here we propose using both fresh (industrial) spruce bark and its bark-press effluents as sustainable sources of natural stilbenoids and pectin. Ultrafiltration removed approximately 90% of the high molecular weight polyphenols as well as enriched stilbenoids from bark-press effluents. Based on a techno-economic analysis, the forest industry would obtain greater revenue potential up to €100 per ton of bark by processing bark side streams compared to their traditional combustion-based strategy if implementing the improved debarking technology. Overall the valorization of stilbenoids and pectin from bark-press effluents or spruce bark offers a promising strategy to produce bio-based, high-value UV-filter ingredients as alternatives to fossil-based ones, and high-grade pectin in an economic feasible and potentially environmentally friendly bolt-on process to the existing mills.
