Abstract[English]
A method of preparing a wind turbine blade for recycling. At least a portion of the wind turbine blade is subjected to a first chemical treatment. The first chemical treatment is selected to degrade a first binding material of the wind turbine blade portion to a significantly greater extent than a second binding material of the wind turbine blade portion. A part of the wind turbine blade portion is separated from the remainder of the wind turbine blade portion after the first chemical treatment has sufficiently degraded the first binding material to release the part from the remainder of the wind turbine blade portion and before the first chemical treatment has significantly degraded the second binding material. This separation of materials by chemical treatment improves the ability of the blade to be recycled.[French]
Procédé de préparation d'une pale d'éolienne pour le recyclage. Au moins une partie de la pale d'éolienne est soumise à un premier traitement chimique. Le premier traitement chimique est sélectionné pour dégrader un premier matériau de liaison de la partie pale d'éolienne jusqu'à une étendue significativement plus grande qu'un second matériau de liaison de la partie pale d'éolienne. Une partie de la partie pale d'éolienne est séparée du reste de la partie pale d'éolienne après la dégradation significative du premier matériau de liaison par le premier traitement chimique afin de libérer la partie du reste de la partie pale d'éolienne et avant la dégradation significative du second matériau de liaison par le premier traitement chimique. Cette séparation de matériaux par traitement chimique améliore la capacité de recyclage de la pale.
