Every year, fisheries, aquaculture farms and seafood processing companies generate large quantities of marine by-products such as heads, viscera, skins, bones, shells and trimmings. Although these materials contain valuable compounds with potential applications in food, feed, cosmetics, biotechnology and other sectors, they are often discarded or directed towards low-value uses. One of the main challenges faced by producers and processors is identifying which valorization opportunities are most suitable for each by-product stream. What products could be developed? Which industries could use them? What is their potential value? This challenge invites participants to develop a digital solution capable of helping stakeholders identify and explore new opportunities for marine by-products. Using production and processing data, teams will create tools that support decision-making, connect biomass streams with potential applications and help unlock new circular business opportunities. The goal is to reduce waste, increase resource efficiency and support the transition towards a more sustainable and circular blue economy.
