Hmm, are they recyclable? Because I can't find clear messaging here in Redmond, WA with Waste Management. The little flyer doesn't address it, and there's no markings on the Amazon envelope that I see. I currently throw them away with regret.
On a related note, I took delivery of a Boosted Rev scooter yesterday. Pretty big box, as one might imagine for a 40-some pound scooter. What amazed me was that after I broke down all the cardboard, what was not recyclable cardboard or paper would have fit in the front pockets of my jeans. Probably less non-recyclable trash than most of my Amazon deliveries.
