Must take a lot of scraps to heat that big ol' Missouri sky.
As someone else here mentioned, I have a problem with "scrap creep". I save little pieces for a rainy day, then it doesn't rain, so I end up buried in little scrap pieces. Every once in a while I'll go through them and toss some, but there are always those little "oh, this might look good in a _______" pieces.
The scrap and chips/dust that I do throw away go into the "green bin" with the rest of the organic yard waste, which is picked up by the city on trash day with the other bins (trash and recycle).
