This seems like a reasonable opportunity to remind people of this fascinating story. It's not exactly a story about eco-friendliness, but it involves gold medals and "recycling." "When Germany invaded Denmark in 1940, [George] de Hevesy dissolved the gold Nobel Prizes of Max von Laue and James Franck in aqua regia to prevent the Nazis from taking them. After the war, he precipitated the gold out of the acid, and the Nobel Society recast Franck and von Laue's awards from the original gold. In 1958, de Hevesy received the Atoms for Peace Award for his pioneering use of radioactive isotopes to study metabolism. Over his career, he published almost 400 scientific publications." copied from: https://www.atomicheritage.org/profile/george-de-hevesy https://www.atomicheritage.org/profile/george-de-hevesy
