Gwent? Wow, that sounds like Lord of The Rings territory, where there would be giant tree people and gnomes..
The documentary is actually about the Zaballeen, a community in Cairo, where everybody survives by going through the garbage and recycling the materials. (They are not the jet-set.) It follows three teenage boys as they learn how to do this, and in one scene their school sends them to Wales, and they visit a modern recycling plant, and they see just how sophisticated the process can be. The movie will be called "Garbage Dreams" although I hate that title, I keep wanting it to be changed to "Zaballeen Dreams"
