This inexpensive system is possible because heavy metals have a positive charge that makes them to be swayed by negative molecules of banana powder after spending a week in the Sun to dry. If the process is repeated, it is possible to purify the water completely. Only in the greater São Paulo, the restaurants weekly discarded almost four tons of banana peel, which if they collect could be used to clean up contaminated industrial water. Meanwhile, if it is discarded, the banana peel takes two years to biodegradarse.
What began as a home-made research was presented as a thesis in the Institute for energy and Nuclear Research) Ipen and Boniolo provided him with the young scientist award. The doctor, who will also present its discovery in the United Kingdom, is next to find partners to develop the project on an industrial scale.
