In WP2, the dried sludge will be used for growing mushrooms, whereas the liquid effluent will be used for microalgae cultivation and production of duckweed and watercress to be used as substrates for mealworm and redworm.


  • Valorise the fresh water aquaculture waste streams to biomass either directly (microalgae, mushrooms) or indirectly (duckweed and watercress for worm rearing)
  • Demonstrate new technologies (microalgal harvesting) and concepts (mushroom and worm cultivation) for sustainable and profitable novel fish feed production
