A man in Argentina who built his house and furniture out of plastic bottles has been so successful that he is now teaching other people how to do the same.
Alfredo Santa Cruz survived during Argentina's economic crash in 2001 by sorting through rubbish heaps in search of items he could sell but now he has found a new way of making a living.
