One aspect is a method for producing a first intermediate product. A feedstock is provided that comprises a first polyester. The first polyester is contacted with a further amount of a first organic compound in a volume section V. The first polyester is contacted with a further organic compound in a volume section Vto obtain a further initial mixture. A weight average molar mass of the first polyester is reduced in the volume section Vto obtain a first intermediate mixture. The first intermediate mixture comprises A first fraction of the further amount of the first organic compound contacted with the first polyester is in the form of a gas, e.g., a vapour.
