Does the statement 'The amount of secondary material output, which is for all practical purposes able to replace one to one the input of secondary material as closed loop is allocated to the product system under study and not to module D' mean that if we use recycled materials originating from the recycling of the product within the same product system, they will not be counted towards module D, for instance, using recycled aluminum for the production of aluminum? according EN 15804:2021+A2:2019
