Officials at the 2020 Tokyo Olympics and Paralympics will be giving out thousands of medals to the world's top athletes. Organizers say they hope to make the gold, silver and bronze awards from recycled metals.
About 5,000 will be manufactured from materials extracted from donated electronic devices.
The idea of electric cars is that they're meant to help reduce our carbon footprint in the world. However there are some questions, such as what do companies do with the used batteries after they've done? Do they simply throw them away? While different companies probably have different approaches, Nissan has an idea: use them to power street lights.
In a program dubbed "The Reborn Light", this sees Nissan take recycled Nissan Leaf batteries and use them to power street lights. This will involve the use of a solar panel that will be used to charge the batteries so that at night, the batteries can then be used to provide lights on the street for both pedestrians and traffic.
The printing paper, "Laser Eco Pet," is made of the company's "Eco Pet" polyester fiber, which is made from used plastic bottles. It has a higher water resistance than normal printing papers made by using pulp. And the paper is hardly torn even when it gets wet so that it can be used outside and near water.
