I've not tried it, but I know some people claim that you can use your printer's heated bed to dry it out. Probably not the most energy efficient way to do it, but seems like it would work.
I have tried it and it works. It is not as good as a dedicated drier and not as energy efficient.
The worst filament was some 5 y old pla that was so brittle it snapped when unrolling from the spool, that just couldn't be fixed on the heated bed. I had to dry it at 50°C for 12h to be usable again.
