A way to Turn Plastic Waste into $78 Million of Biofuel
16-year-old Egyptian student Azza Abdel Hamid Faiad, meanwhile, was at work finding a way to make use of waste plastic. The young scientist discovered a catalyst(催化剂) that could turn Egypt’s one million tons of annually waste plastic into a $78 million worth of biofuel each year. She hopes that the development could “provide an economically efficient method for production of hydrocarbon(碳氢化合物) fuel,” and many appear to agree; Faiad has been awarded the European Fusion Development Agreement Award at the 23rd European Union Contest for Young Scientists, and is seeking patents for her discovery.
A Pee(尿)-Powered Energy Generator(发电机) Created by Four Nigerian Teenagers
Four Nigerian teenage girls amazed visitors to the Maker Faire Africa with their pee-powered energy generator. Able to source an impressive six hours of power from just one liter of urine(尿)， the 14-and15-year-olds’ renewable energy generator holds interesting possibilities for providing electricity in remote areas or in disaster zones.
Turning Banana Peels(皮) into Bioplastics
16-year-old Turkish student Elif Bilgin developed her very own technique for turning the ordinary banana peel into bioplastics, a discovery which she hopes could reduce dependence on petrol chemicals and make use of some of the 200 tons of banana peel thrown away daily in Thailand alone. Her development relies on the properties of the starches(淀粉) and cellulose(纤维) found in the outer layer of banana peels, which through a chemical process developed by Bilgin herself, can be transformed into a non-decaying(不腐烂的) bioplastics.

For many teenagers who are growing up in cities, the first things that catch their eyes when they come to the countryside are the animals, farm tools and above all, the rural scenery that is very different from that in cities.
But when Wang Zhicheng, a 17-year-old boy from Qingdao No. 2 High School went to his mother’s hometown for the first time during Spring Festival, he was shocked by the terrible condition of the roads.
Roads in the small village in Heze, Shangdong province were muddy and bumpy(崎岖的). “Complaining doesn’t solve any problems. I wondered what I could do to help rebuild the roads,” Wang said.
He talked to villagers and learned that a lack of money had been the major problem that had gotten in the way of the rebuilding project. Wang decided to donate 3,000 yuan of his gift money he had received for Chinese Lunar Ney Year over the past three years. But it was really only a drop in the ocean. What else could he do?
Then he realized he could use the Internet. Wang said he remembered the reports he had read on social networking sites about crowd funding helping cancer patients and other charity projects. So why not try Internet crowd funding for the village road?
Wang released the information on the Internet on Feb 22. “I was not sure whether I had expected too much from the Internet, but it was worth trying,” he said. Much to his surprise, he achieved that goal in just 10 days. Money continued to be transferred(转入)into the account and up to now, a total of 50,000 yuan has been collected.
The new road will hopefully be ready by the end of this year. “I had thought charity was just showing off, but I came to realize that it is a systematic project. It not only helps those in need, but also highlights the positive side of life for all the people involved.”
