Are there ground-up nails and old pallet wood in MDF, or is that a woodworking myth?
This woman had an answer. – Editor “MDF is not made out of pallets, at least in the plant my husband works at that makes MDF. They use the branches and scraps that can’t be used for veneers. All bark is removed before the process even begins, the chips are then dried in huge heated air tunnels. Pieces that are too large, too wet, or are not wood, don’t make it to the top and are dropped out of the bottom. They have strict quality control, and on-site labs. All boards are metal tested, and batches are lab tested to assure top quality in every board. You can cut MDF with a router. As with any woodworking, wear a mask and glasses.
