How do you dispose of PLA

Answered By: Donald Scott Date: created: Jan 30 2022

PLA has a lower melting point than other plastics, so it can’t go into the same bundle with the rest.

The two main ways to recycle PLA are to hand it over to a recycling plant that knows how to handle it or to grind it up and extrude it into new filament..

Technically yes, PLA is (mostly) food safe. However, there are other aspects of 3D printing in PLA that can cause problems. Firstly, a 3D printed cup is not likely to be watertight. Secondly, the layered effect leaves areas that bacteria can flourish in, so your PLA cup is only usable for 1 or 2 drinks.
