Waterless Toilets Can Help Save the Environment

Dec 06, 2016 09:18 AM EST

This latest technology may be the best one yet, as waterless toilets are aimed to save the environment. They have been designed to use no water at all for flushing to reduce the need to have a big septic tank underneath the house. They would also allow homeowners to have their own tiny wastewater treatment system.

So how do waterless toilets work?

According to a report from How Stuff Works, wastes are expected to fall within a rotating container which flips over when the lid of the toilet is closed and goes back upright when the lid is opened. Liquid and solid waste will now fall into a chamber with water. Then a rotating wiper, or scraper, will be cleaning the container of any leftover waste.

The next question in everyone's mind is where the waste goes. According to Science Alert, these Nano Membrane Toilet uses nanofibers to remove water vapor and other odors into a vertical tube at the rear of the toilet.  Once the waste reaches the water-filled chamber, solids are expected to settle at the bottom while liquids are expected to settle at the top.

The solid wastes would go through a rotating mechanism that breaks it down into smaller parts, dries it up and covers it with odor suppressing wax. The liquid waste is then condensed into clean water, and all its impurities will be filtered out together with solid wastes.

The last question in everyone's mind is where it is available. This toilet has been developed by a team of researchers from Cranfield University. According to a report from the Business Insider, the developers of this mechanism has been backed up by the Bill and Melinda Gates foundation to be distributed all throughout rural areas in the world. It has been designed to accommodate up to 10 uses for less than five cents every day.
