CROAL research project consists of improving the purification of biogas with microalgae and applying Zero valence iron nanoparticles encapsulated in a carbon matrix (also called OPS), obtained from a residue from the manufacture of olive oil (vegetable water).

To evaluate the effect of adding Smallops nanoparticles to a biogas purification system with microalgae, batch tests were carried out.

The team of researchers for the project is made up of personnel from the University of Valladolid together with the collaboration of SMALLOPS.
