Recycling of PLEXIGLAS®:
Post-consumer recycling of back-light units of PMMA screens

Backlight units of screens are often made of high-purity polymethyl methacrylate (PMMA) and are therefore ideal for chemical recycling. In this process, the polymer (PMMA) is returned to the monomer (MMA) by heating, which can then be used as a raw material for polymerizing PLEXIGLAS® or other products such as reactive resins.

Products made from this have a significantly reduced carbon footprint compared with virgin material. This process clearly distinguishes PMMA from other materials where chemical recycling only produces precursors for monomer production, such as pyrolysis oils.

What does PLEXIGLAS® have to do with car design? For over 60 years, PLEXIGLAS® molding compounds have been a driving force behind the auto industry. Why? Because the multifaceted ways in which PLEXIGLAS® can be formed open up virtually endless possibilities for design. One shining example is highly transparent PLEXIGLAS® whose top light-guiding properties and UV stability make for innovative automotive lighting systems.
