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.

PLEXIGLAS® Optical HT

PLEXIGLAS® makes even red lights green.

PLEXIGLAS® has the ability to take on any color – while also remaining green. At its basic structure, PLEXIGLAS® contains no halogens, no aromatic compounds, and no plasticizers. It is nontoxic, noncarcinogenic, and nonmutagenic. Best of all, at the end of its life, it is fully recyclable. PLEXIGLAS® is the material of choice for your green products.

For PLEXIGLAS®, reincarnation is old hat. We call it “recycling.”

We believe in reincarnation. The reincarnation of PLEXIGLAS®, at least. Because PLEXIGLAS® is so pure that it can be broken down into its basic components again to be reborn as new PLEXIGLAS®. Few plastics can achieve a rebirth of this kind – this is not downcycling, but true recycling in the interests of a circular economy!

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.
