The Profile Smart was one of several environmentally friendly toilet and toilet-related items on display at this year's Green Product Expo.

It has a built in sink that provides fresh water for hand washing, which then drains into the toilet tank for the next flush.

In addition to utilizing water that would normally be washed down the drain, the toilet is highly efficient. It averages less than a gallon per flush.

The average household spends as much as $500 per year on water and sewer bills and can save about $170 per year by installing water-efficient fixtures and appliances, according to the Environmental Protection Agency.

What's more, the EPA estimates that there are at least 36 states now projecting water shortages between now and 2013.

The Profile Smart, which is made by an Australian company called Caroma, costs $600.
