I recycled the cardboard over about 3 weeks. The recycler comes once per week. Most of the foam I placed in trash can as I could fit it. It took about 2 weeks as the trash pickup is twice per week. I kept a small piece of foam to use when I am working down on my knees. I am 74 and it really helps. Th large piece which packed the core I am keeping for the time being as I makes a good resting piece when I place my mower in my front loader to work on it. I rest the entire front loader on this big, heavy foam box like structure. It makes working on the mower lots easier to have it raised up off the ground.
Good luck
