Relevant materials will be provided by the Scandinavian industry partners. The materials will be chemically characterized and compounds with potential biostimulant effects on crop plants will be investigated, while concurrently checking for possible biotoxicity. The chemically profiled effects of these materials on plant growth will be assessed, both in a pre-processing state and after appropriate treatment is applied, e.g. extraction and/or composting.

The project also includes an innovative treatment of organic fish waste from aquaculture, which will expedite approval of such materials in growing media. Adjoining the effort is a study on impregnation technology to utilize biochar, which is in itself useful for soil amendment, after impregnation with extracts of BLUE materials as a carrier of nutrients and other valuable compounds into agricultural soil.

To proof the concept, promising materials (assessed from chemical characterization) will be tested in real growing conditions in greenhouse and eld. The logistics and related costs required for establishing a relevant value chain for producing fertilizers and/or biostimulants will be assessed by interviewing collaborating industry partners and surveying potential customers.
