摘要： The invention relates to a method for economically using styrene-containing plastic waste as raw material for new high-quality plastic products as part of a raw material recycling process, optionally having the steps of pre-treating a styrene-containing starting material, decomposing the styrene-containing starting material in a suitable reactor, discharging and collecting the resulting gases and condensing the low-molecular products in a suitable separator, separating the collected low-molecular components of the previous step by means of a fractioning distillation process, and optionally additionally decomposing the styrene oligomers in a steam cracker.
