據外媒報道，比利時根特大學科學家發明一種用太陽能把尿液變飲用水和肥料的機器，相關技術可用在農村和發展中國家。
廢水凈化方式有多種，然而本次根特大學（University of Ghent）研究系統采用一種特殊的薄膜，不但符合能源效率，還可應用在供電困難地區。
據報道，根特大學研究員德瑞斯（SebastiaanDerese）稱，使用太陽能，經一個簡單過程，就可把尿變肥料和飲水。
研究人員先用大水塔集尿，再用太陽能鍋爐加熱，然后液體流過薄膜時，會把鉀、氮、磷等成分分離出來，并將水還原。
部分原文報道如下：
A team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries.
While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid.
“We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy,” said University of Ghent researcher Sebastiaan Derese.
