Smart Stone is an innovative lawn and garden stepping stone made entirely of recycled and recyclable materials – roughly 80 plastic shopping bags per stone and sawdust. Smart Stone looks and performs like concrete and natural paving stones at a fraction of the weight, with each stone weighing less than five pounds. Compared to their concrete counterpart’s weight of more than 30 pounds per stone, Smart Stone can easily be handled by anyone and transported much more economically and sustainably than concrete or natural stone.
