@andrhia I'm a hobbyist woodworker, would you like me to send you some from my dust collector? 😂
At the very least, apparently most saw dusts are mostly flavorless, and edible! (Mine are not, I work with exotic hardwoods a lot and they're pretty toxic, so pls no eat).
You can even use them to bulk up rice crispy treats if you want! https://www.youtube.com/watch?v=AKDal51f5LU
