Chariots of steel: Barcelona’s hidden army of scrap recyclers
They are everywhere and yet they are almost invisible, living below the social radar as they crisscross the city pushing supermarket trolleys piled with metal tubing, old microwaves and empty beer cans.
The chatarreros are Barcelona’s itinerant scrap-metal collectors, and there are thousands of them. Most are undocumented migrants and so there is no official census, but Federico Demaria, a social scientist at the University of Barcelona who is conducting a study of the informal recyclers in Catalonia, believes there are between 50,000 and 100,000 in the region. About half are from sub-Saharan Africa; the rest are from eastern Europe, elsewhere in Africa and Spain.
