The invention discloses a recovering method and a recovering system for a fluorine-containing backboard of a photovoltaic module. The recovering method comprises the steps that S1, crushing treatmentis carried out on the fluorine-containing backboard of the photovoltaic module, and fragments or particles of the fluorine-containing backboard are obtained; S2, organic auxiliary materials used for bonding the fragments or the particles of the fluorine-containing backboard are added into the fragments or the particles of the fluorine-containing backboard, mixing is carried out, and a raw materialmixture is formed; and S3, the raw material mixture is subjected to hot press molding to form a plastic product in a fixed shape. The recovering system comprises a crushing device, a mixing device and a hot press molding device and is used for achieving the recovering method. By means of the recovering method and the recovering system, the problem that the fluorine-containing backboard is difficult to recover is solved, the surplus value of the fluorine-containing backboard is utilized, and pollutants polluting the environment cannot be generated.
