The present invention relates more particularly to a method and to a facility for drying such a product, making it possible to implement a hydrothermal carbonization operation on reactorfollowed by a filtering and drying operation, preferably on a heating filter press. In order to dry said product in the heating filter press, a heat-transfer fluid from a heat exchangeris made to flow in said heating filter press. The heat exchangeris arranged so as to transfer, to the heat-transfer fluid, at least some of the heat contained in the product to be dehydrated that is output from the reactor
