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.

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.
