I think I know the answer, but I'll ask anyway.

We have lumber scraps left over from construction. Some are pine odd
lengths, some treated pine, and a bunch of particle board.

I know NOT to burn treated lumber.

I THINK that untreated regular pine will burn fine in our backyard
fire pit.
What about particle board? I know it has glues in it, and think it
probably should go to the landfill, but thought I'd ask youse guys.

It's not allowed to be burned in WA State. Check with your local air quality
folks.
