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.
Fai uns 20 anos, empezei literalmente a xogar no meu garaxe, intentando averiguar como separar estes materiais tan parecidos entre eles, e ao final recrutei a moitos amigos, do mundo mineiro, de feito, e do dos plásticos, e comezamos a ir a laboratorios de minería por todo o mundo.
