Abstract

The invention relates to a process for the production of a recyclable product (1, 8, 9) made from a first material, wherein before or during the production of the product (1, 8, 9) a first marking material is added to the first material and the product (1, 8, 9) is produced from the first material with the admixed marking material, wherein the first marking material can be automatically detected in a recycling plant in the first material of the product (1, 8, 9) after the production thereof. The invention also relates to a process for the recycling of a product (1, 8, 9), wherein the product (1, 8, 9) is manufactured from a first material, to which a first marking material is added, wherein the product (1, 8, 9) or pieces (22) of the product (1, 8, 9) are separated from one another and/or from other objects in a recycling plant, in that the first marking material is detected in the first material of the product (1, 8, 9) or the pieces (22) of the product (1, 8, 9), and the product (1, 8, 9) or the pieces (22) of the product (1, 8, 9) are separated from one another and/or other objects, in which no marking material or a different, second marking material is detected.
