What are the main challenges? 

2GETHER focus on linking the use of blue-green resources and waste in a sustainable, circular and convergence research approach. The main challenges relate to the ambiguity of food sustainability, reducing blue-green food loss and waste, and how to add value to the resources. How should a vital circular economy based on valorization of residuals be arranged, in a way that both blue and green economies are adapted to innovation? How should we in the future move from waste to feed to food by reusing of both green and blue residuals to promote sustainable food consumption and facilitating the shift to sustainable diets. Challenges also arise when studying food quality, food safety, tastes, flavours, regulations related to e.g., toxicity and pathogens when new blue and green resources are in play. 

Blue resources and side streams such as shellfish, jellyfish, seaweeds, and small pelagic fishes can be used as bio stimulants, micro and mineral rich super fertilizers, organic fertilizers, for soil quality improvement, and as a sustainable protein source. In addition, using blue resources can aid in moving aquaculture and sea farming on land. Insects may represent a possible link between blue and green and even as possible feed solutions. 

Current resources in the HUB include experimental sites and pilot plant, as well as chemistry/ biotech labs for testing valuable ingredients, and biorefineries for extracting and fractionating biomolecules. Socioeconomic living labs alongside the supply chains, and feed and food production labs are also represented in the HUB. 

The HUB expects to be able to characterise the efficient use of blue-green waste and resources from farm to fork, through convergence research approach. In addition, the goal is to identify links between use of friendly blue-green resources and waste using an iterative approach. Finally, the HUB work should facilitate policy advice on the macro, meso, micro level. 

What kind of research areas would complement the HUB research? 

The HUB would more than welcome researchers from social sciences for consumer panels, as well as researchers from marketing and communication for image branding, as acceptance and adoption are a key for the success of the blue and green innovations. Also, researchers with a background in economy would be highly appreciated to look at cost-benefits of integration of blue into green and vice versa.
