Computer-implemented method for sorting of plastic compounds

A system for sorting of plastic compounds, comprising:

• a computer-based database comprising entries on a plurality of markers each identifying a specific plastic compound;
• at least one receiver configured to receive scan data from a sample of a plastic compound;
• at least one processor configured to identify a marker in the sample of the plastic compound based on the received scan data and the plurality of markers of the database, wherein the marker includes a chemical tracer used to tag a recycled material in the sample of the plastic compound;
• and
• at least one sorter configured to sort plastic compounds based on the identified marker of the sample of the plastic compound.
