Why is this not wasteful?

Our solution is environmentally-conscious and cost-effective...you get a month's worth of litter with our one-of-a-kind, recyclable box...and it's all shipped to you - with FREE SHIPPING. Our box is made from 100% recycled cardboard and our litters are derived from natural materials. At the end of the month, simply throw the litter away in the trash, and recycle the box!
