Same as above, cut the tape and fold it to fit in trash can. Once in a while, may need to cut a big box smaller to fit receptacle. If I really need to tackle some cardboard, box cutter is approved tool with multiple replaceable blades. I went to town on my new lawn mower box, enjoyed using my knife.
This.
I will just cut the tape if I can, but some boxes are just too big to start with to ft in the recycle container, and a little breaking down is needed. For that I usually have an old Stanley 99 on a shelf in the garage by the recycle bin.
