The world's first solar toilet

On March 14, US news agency ABC News cited sources of the University of Colorado, USA , said it has successfully built a solar toilet that can recycle human waste into biochar.

The report said that through this 'no water' toilet, human waste and urine 'will be transformed' into 'high porous biochar' for cooking.

'In addition, biochar is buried in the soil that will help preserve the nutrients in the soil layer, which is useful for agricultural farming,' - environmental engineering professor Karl Linden at the University of Colorado told ABC News.

Mr. Linden said that the world's first solar toilet design project was funded by the Bill & Melinda Gates Foundation, 777,000 USD.

A family toilet can be used for 4-6 people. Meanwhile, solar toilets can be used for many households when installed in public places.

Solar toilet is operated based on 8 mirrors absorbing sunlight and transmitting this solar energy through fiber optic cable to heat 'waste-containing reaction chamber ' with temperature up to 300 degrees C. Temperature This will 'disinfect' and slowly concentrate the waste and the final product to be produced is biochar.

According to indianexpress.com, solar toilet invention is a practical solution to solve the current shortage of toilets. The November 2013 report of the United Nations said that there are about 2.5 billion people in the world who currently do not have access to improved sanitation and up to 1 billion people still go indiscriminately.
