It might seems strange to ask this question in the 'Off Topic Forum' but I see the uses for chips as off topic.

I am wondering what other do with the perhaps bags or bins full of wood chips. It doesn't take much milling of lumber to create a fair volume of chips. I have struggled to find a good use for them, but this year I have been using them as mulch around my tomato plants. Putting mulch down helps prevent bacteria and viruses from getting onto the plants, so lots of maple and other hardwood chips have been going down around my plants.

Other uses?

I try not to get other items like mdf or particle board mixed into my actual wood chips. Not always possible of course but I mostly am successful.
