Hi there! How nice that you came to this site. You have probably just done a search for the gold in our Gold Digger Game and you are curious about some more (background) information, research and sources of the treasure questions.
First of all, we would like to refer you to a number of reliable websites and research pages. Here you can read all about the latest figures and developments in E-waste, recycling and associated themes.
For the Treasure Questions we used all kinds of sources. Sometimes the surveys are outdated or done on a small scale, but for the game we liked to include all kinds of questions. Below you will find all sources listed per question!
