KIT Researchers Propose New Ways to Utilize Wastewater

Written by AZoCleantech

A team of researchers from the “Water-Energy Group” of Karlsruhe Institute of Technology (KIT) are studying possibilities to eliminate the issues relating to wastewater.

Wastewater is considered to be of no use. Washing water is said to an average temperature of 30 °C. Toilet water can be used not only for producing fertilizers or biogas but also as valuable resources that otherwise is dumped in the sewer system unused. What is worse is that annually, over 2 million people die from diarrheal diseases because of the wrong use of wastewater.

Although water covers around 72% of the Earth’s surface, only 0.3% can be utilized as drinking water.

With that in mind, wastewater is no waste. It contains thermal energy, chemical energy in the form of carbon compounds, and valuable plant nutrients. Now, we have to develop processes for the use of these resources.
