Project Title

ReWali

Project description

Nutrient-laden wastewater that cannot be discharged into the sewer system often accumulates on farms. This includes, for example, rainwater or bathing water for ducks and geese. This water contains washed-off nutrients or portions of poultry droppings. Purifying the water by recovering the nutrients and transferring them to a sustainable recirculation system, is the basic idea of the ReWali project. First, plants bind the nutrients into biomass. Native, widespread and so far almost unused: the duckweed. In summer, it forms a dense carpet of plants on water surfaces and binds nitrate and phosphorus from the water, among other things. The small floating plant is very rich in protein and contains starch and vitamins, which makes it a raw material for protein-rich feed. In addition to fresh feeding, the duckweed can also be ensiled or dried and pelletized. What this can look like in practice on the farm will first be investigated using goose and fish as model animals.
