Hans Priks is creating a special environment for bacteria to work in. He uses hydrogel cubes.
The cubes keep the bacteria inside. The cubes are like a hotel for bacteria. There, the bacteria can work.
Hans Priks tested the cubes with brewer's yeast. The cubes worked well. They can be reused.
The cubes can also be used in space. The cubes may help in utilizing waste. Hans Priks continues to work on improving the cubes.
