Abstract: A method for producing an air-laid product or a non-woven product from a starting material includes: comminuting starting material into a comminuted material in at least one comminution line by at least one comminuting device; feeding the comminuted material into at least one material buffer; removing the comminuted material from the at least one material buffer; metering the comminuted material by at least one metering device; supplying the comminuted material to at least one processing line with at least one defibration system in which the comminuted material is defiberized into a defiberized material; and feeding the defiberized material into a production machine and processing the defiberized material into an air-laid product or a non-woven fabric. The at least one metering device is controlled in such a way that a continuous mass flow of defiberized material is supplied to the production machine.
