So about 20 years ago, I literally started in my garage tinkering around, trying to figure out how to separate these very similar materials from each other, and eventually enlisted a lot of my friends, in the mining world actually, and in the plastics world, and we started going around to mining laboratories around the world.
所以大约20年前，我在车库里开始着手 尝试如何把这些非常相似的材料 互相分离 最终我结交了很多朋友 采矿业的朋友，塑料领域的朋友 我们开始拜访世界各地的采矿实验室
