| Résumé : |
Today plastics recycling is usually only classified as being either mechanical or chemical. This view ‧ignores the fact that the main difference between the two is whether physical or chemical reactions are taking place. However, precise differentiation is crucial for any assessment of the possibilities and limitations of plastic ‧recovery processes and whether materials are actually being recycled or merely their raw materials recovered. |

- Fig. 2 : Process steps involved in physical and chemical recycling : while physical recycling uses the material direct, chemical recycling only serves to recover feedstocks and requires an (energy-intensive) polymerization step before these can be reused in plastics |
