Adaptable sponge soaks up phosphate from polluted waterways for reuse

Phosphate pollution drives environmentally damaging algae blooms, and scientists have developed a new material that could help tackle the problem

The phosphate found in the Earth’s crust is a key ingredient for the growth of aquatic plants and animals, but human activity is washing far too much of it into our waterways. One consequence of this is the algae blooms that coat the surface of some lakes and rivers, which starve other marine organisms of the oxygen they need to survive. A new sponge-like material likened to a Swiss Army knife could help scientists tackle this problem, with its ability to not just capture phosphate from water sources but allow it to be collected for reuse.
