Here's the summary for the wikipedia article you mentioned in your comment:
Thermal depolymerization (TDP) is the process of converting a polymer into a monomer or a mixture of monomers, by predominantly thermal means. It may be catalysed or un-catalysed and is distinct from other forms of depolymerisation which may rely on the use of chemicals or biological action. This process is associated with an increase in entropy. For most polymers thermal depolymerisation is chaotic process, giving a mixture of volatile compounds. Materials may be depolymerised in this way during waste management, with the volatile components produced being burnt as a form of synthetic fuel in a waste-to-energy process. For other polymers thermal depolymerisation is an ordered process giving a single product, or limited range of products, these transformations are usually more valuable and form the basis of some plastic recycling technologies.^article^ ^|^ ^about^
