A group of high school students in Italy invented a vending machine with the help of a teacher. It does not receive money. As long as you put waste plastic bottles into the machine, the machine can turn waste into treasure. First, the plastic waste is decomposed into small particles , Then printed by a built-in 3D printer beautiful and stylish smart phone shell back to you.
Oddity Central, the US news adventures site, reports that it is unclear whether the machine is made with live phone cases on-site after the plastic is put on, or by prefabricated handsets for people who put plastic into it.
However, students hope to bring more young people to environmental protection in this way, naming the machine as 'my promotional move' and have now made four prototypes and are looking for mass-production partners.
