o:7084 Bioeconomic potential of valorizing blackcurrant (Ribes nigrum L.) press residues Bioekonomski potencijal valorizacije ostataka presovanja crne ribizle (Ribes nigrum L.) en Abstract: The concepts of sustainable development and circular economy require finding innovative ways for more efficient use of resources, produced raw materials, and waste. The aim of the research was to assess the economic and ecological justification of valorizing blackcurrant pressing residues. For this purpose, a semi-structured interview was conducted with a blackcurrant producer, as well as with three potential service providers for the processing of pressing residues. The results show that the valorization of blackcurrant pomace is an ecologically and economically responsible approach to production. There are several ways to valorize blackcurrant pomace, and in this study, the emphasis is on extracting oil from the seeds and obtaining flour from the dried pressing residues. The economic justification of valorizing blackcurrant pressing residues has been identified, as the produced oil adds value to the pressing residue by 2.87 €/kg, and the flour produced by all three processors by 6.60 €/kg, 5.87 €/kg, and 5.57 €/kg, respectively. It was unequivocally established that value chains for blackcurrant pressing residues exist and that it is possible to add value to a currently worthless by-product, thereby increasing profits, removing waste from the production chain, and making the agricultural enterprise more competitive. The paper points to the need to integrate bioeconomy principles into agricultural residue management practices. Sažetak: Koncepti održivog razvoja i cirkularne ekonomije nalažu da se pronađu inovativni načini za efikasnije iskorištavanje resursa, proizvedenih sirovina i otpada. Cilj istraživanja bio je da se proceni ekonomsko-ekološka opravdanost valorizacije ostataka presovanja crne ribizle. U tu svrhu obavljen je polustruktuirani intervju sa proizvođačem crne ribizle, kao i sa tri potencijalna pružaoca usluga prerade ostataka presovanja. Rezultati pokazuju da je valorizacija komine crne ribizle ekološki i ekonomski odgovoran pristup proizvodnji. Postoji nekoliko načina za valorizaciju komine crne ribizle, a u ovoj studiji akcenat je stavljen na ceđenje ulja iz semena i dobijanje brašna od osušenih ostataka presovanja. Ekonomska opravdanost valorizacije ostataka presovanja crne ribizle je identifikovana, budući da proizvedeno ulje dodaje vrednost ostatku presovanja za 2,87 €/kg, a brašno proizvedeno kod sva tri prerađivača za 6,60 €/kg, 5,87 €/kg i 5,57 €/kg, respektivno. Nedvosmisleno je utvrđeno da lanci vrednosti ostataka presovanja crne ribizle postoje i da je moguće dodati vrednost trenutno bezvrednom nusproizvodu i na taj način povećati profit, ukloniti otpad iz proizvodnog lanca, a poljoprivredno gazdinstvo učiniti konkurentnijim. Rad ukazuje na potrebu za integrisanjem principa bioekonomije u prakse upravljanja poljoprivrednim ostacima.
