Method for recycling polyolefin containing waste

The invention refers to a method for recycling polyolefin containing waste by using a solvent with a specific Hansen parameter and contacting this mixture with a liquid filtration aid before separating the polyolefin from the mixture. The method comprises the following steps: ¢ Mixing the polyolefin containing waste with a solvent having a Hansen parameter & H from 0.0 to 3.0 MPa 1/2 ; ¢ Contacting this mixture with a liquid filtration aid having a Hansen parameter & H > 4.0 MPa 1/2 ; and ¢ Separating the polyolefin from the mixture.
