Be forewarned you'll need a plan for disposal of the 'waste' if you break your pallets down
There are many great ways to use that "waste" wood after you break down your pallets. Some of the wood could be used for small projects, like birdhouses. I used a lot of waste pallet wood in my fire ring for campfires. However, recently I built some more pallet wood raised beds and used that waste wood I had on hand to make hügelkultur raised beds, along with logs from trees that I had saved. That waste pallet wood made a great filler in between the larger log rounds.
At one time, I used a couple 5-gallon buckets full of pallet wood bits and pieces and ran them through my SunJoe woodchipper. It made nice wood chips for litter and nest box material. However, it was a lot more work than it was worth on my small electric woodchipper. Maybe a better idea if you have a larger gas woodchipper that can chip up the wood much faster.
