Here's a million dollar idea: invent an odorless diaper pail. No, not one of those that you can go find on Amazon right now that claims to be odorless. One that, no matter what horrific-smelling diapers lie within, actually is. One that, when closed, has something akin to a hermetic seal.
Each Sunday night I take out the garbage and as part of that job I empty the diaper pail. We keep ours outside the back door because of the stench that would otherwise permeate the house. If we could keep it inside, conveniently next to the changing table, that would make life easier, even if only by a little bit.
Some will say we should use cloth diapers instead and, voila, problem solved. We tried it - we bought a bunch of Fuzzi Bunz. My question for you is - have you ever used cloth diapers? Do you like the idea of human waste in your sink or in your washing machine? Do you know what a chore they really are? I recycle and respect the environment as much as the next person does, but cloth diapers are a tough sell.
Something tells me that a truly odorless diaper pail for the consumer will never be. But if you can come up with one it's a million dollar idea. While you're at it, figure out how do one for dog poop as well.
