Clean Technica writes that for those considering building waste management strategies, it might be time to look at the toilet bowl.

Swedish-based BioLet has manufactured waterless toilets for 35 years and indicates odor is not a problem. In the US the average American uses 7,665 gallons (29,000 liter) of water each year just flushing the toilet. In Sweden waterless toilet systems are required in many places.

Sture Andersson, BioLet’s founder, said that waterless toilets are getting more and more common as environmental awareness increases across the globe. 

“These days, waterless toilets – and toilets that use less water – have become very common; in some areas they are even considered a necessity. Waterless urinals can be found at many airports or sport arenas, and people are gradually becoming more educated about wise water usage", he said. 

The principle is very simple. Human waste is transformed into a dry, odorless material that can easily be disposed of, or even recycled back to the earth, Clean Technica wrote.
