Chemical recycling are processes in which a plastic polymer is chemically broken down to monomers and subsequently restructured into new polymers used for new plastic production. This paper does not consider any other type of recycling, for example bio recycling. 3.1. Thermal cracking (conventional pyrolysis)

De enkelte plasttyper kaldes derfor også ofte for polymerer. Betegnelsen stammer fra det græske “polymeros”, der kan oversættes til poly = mange og meros = dele. En polymer er derfor et meget stort molekyle – et såkaldt makromolekyle – sammensat af mange ens byggestene. Polymers with microcrystalline regions are generally tougher (can be bent more without breaking) and more impact-resistant than totally amorphous polymers.

Wool, cotton, silk, wood and leather are examples of natural polymers that have been known and used since ancient times. Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers. Polymers are constructed from relatively small molecular fragments known as monomers that are joined together.
Plastics additives are all chemicals which are used to polymerize, process or to modify end use properties of plastics. They may be all chemical used in plastic

Betegnelsen stammer fra det græske “polymeros”, der kan oversættes til poly = mange og meros = dele. Lactic acid (LA or 2-hydroxypropionic acid) is the most widely occurring hydroxycarboxylic optical active acid.
