A great deal of research is currently being carried out in this field, and it represents a fundamental alternative to current energy problems. It consists in storing carbon dioxide for reuse or positive valorisation for the environment. In this context, the main objective of the present work is to develop an innovative technique for cracking carbon dioxide (CO2). Three methods have been used for this cracking. The first is electric field cracking, the second catalytic plasma cracking and the third magnetic resonance cracking. These three cracking processes were used to break the bond and extract the oxygen O2, and the carbon C. These two elements were subsequently used in wastewater treatment. The technique used is percolation filtration through a purifying matrix consisting of sea sand with a particle size of 160 µm, agricultural soil rich in silica and carbon.
