ETH Zurich scientists develop low energy method to recycle acrylic glass

Researchers at ETH Zurich have developed a simple and low-energy method to recycle acrylic glass, Good News Network reported. The new process breaks the material down almost entirely into its original building blocks, achieving a yield of up to 98 percent. This advancement makes high-quality recycling realistic and affordable for commercial use for the first time. [1]

Acrylic glass, also known as PMMA or Plexiglas, is commonly used in windows, automobile taillights, furniture, and protective barriers. Previous recycling methods were often too costly, overly complicated, or too energy-intensive for companies to adopt. Because of these technical barriers, the vast majority of acrylic glass previously ended up as environmental waste. [1][2]

Poly(methyl methacrylate) is a transparent synthetic thermoplastic derived from methyl methacrylate that serves as a lightweight and shatter-resistant alternative to traditional glass. It is widely sold under brand names such as Plexiglas, Perspex, Lucite, and Acrylite, and is frequently applied in casting resins, coatings, and inks. [2]

The new recycling technique overcomes historical industry obstacles by drastically lowering energy requirements and operational costs. Good News Network reported that the process opens up practical avenues for manufacturers to repurpose waste acrylic products back into new material directly. [1]
