Reclaiming raw materials from sewage

Ecotechnology for sewage using algae. Valuable raw materials such as phosphorus (nutrient cycle) are reclaimed, while simultaneously decomposing substances such as medicine residues and pathogens to prevent water pollution.

By recycling scarce phosphorus from human excrement, 22% of world demand for it can be covered.

Microalgae purify the waste water. The nutrients serve as fertiliser for the rapidly growing algae.

Recycling the phosphorus from excrement creates a circular economy. Nutrients return to the soil. This method can be used across the world while creating a valuable product: algae biomass.
