Questions & Answers about Tienes que meter el cartón en el contenedor azul.
Why does this sentence use meter instead of poner for "to put"?
Does cartón mean "carton", like a milk carton?
Not exactly. Cartón refers to the material "cardboard" or a large cardboard box. If you want to talk about a milk or juice carton in Spain, you would usually use the word brik (from Tetra Brik) or envase.
Why use contenedor instead of basura or papelera for "bin"?
In Spain, a contenedor refers specifically to the large, public recycling bins or dumpsters found on the street. A papelera is a small wastebasket (like you might have in an office), and basura is the general word for garbage or your home trash can.
Why does the sentence specifically mention the blue bin (contenedor azul)?
Spain uses a standard color-coded recycling system for its street bins. The contenedor azul is exclusively for recycling paper and cardboard (papel y cartón), making this a very common everyday instruction.
