Acrylic (PMMA) Recycling
PMMA (polyMethyl MethAcrylate) is a clear, glass-like plastic, that is formed using acrylic acid. Commonly PMMA is used as a safer and stronger replacement for glass, it’s better at insulating too! PMMA is half the weight of glass and does not shatter, it can also be cut and shaped with a saw. Acrylic will not decay over a period of decades if cared for properly.

PMMA is very difficult to recycle, involves a lot of energy and the toxic contents of the acrylic are a potential environmental hazard. Equally, acrylic is not biodegradable, and so wont break down over time. One method of recycling is pyrolysis, in which the PMMA is extremely heated in the absence of oxygen. Another procedure is depolymerisation, which involves heating the acrylic until the monomers are separate.
