Can pyrex be recycled

Generally not.

Pyrex is heat resistant and therefore can not be recycled in the same way as conventional glass due to its heat resistance. In fact it can spoil large quantities of recycled glass, and should never be placed in the recycling box.

Theoretically, offcourse, any material can be recycled if a new use is found for it, pyrex could be e.g. be ground up and used for road foundations, however, the quantities household produce are not large enough to make a separate pyrex-recycling programme economically feasible.
