Glass makes noise — throw it out in the morning.
VEH-tro — the 'e' is open, as in English 'bet'; roo-MOH-reh — stress the second syllable.
This is typical neighbour-to-neighbour advice in Italian apartment buildings. Glass recycling bins (campane del vetro) are often shared street containers, and dropping glass late at night is deeply antisocial.
The campana del vetro (glass bell container) is a large green street container shared by multiple households. Because glass makes a loud crash when dropped, Italian social norms — sometimes reinforced by building rules — discourage putting glass out late at night. Morning disposal is the considerate choice.
Non buttare il vetro di sera: i vicini si lamentano.
Don't put glass out in the evening: the neighbours complain.
Direct social norm statement; lamentarsi means to complain.
La campana del vetro è in fondo alla via.
The glass bell container is at the end of the street.
Tells you where to find the shared street container.
Posso usare bottiglie e vasetti di vetro di qualsiasi colore.
I can use glass bottles and jars of any colour.
Clarifies that Italian glass bins accept mixed colours, unlike some other countries.
In Milan, Rome, and most Italian cities, campane del vetro are shared street containers placed every few blocks rather than individual household bins. Some communes have switched to door-to-door glass collection to reduce noise complaints, but the street bell remains the most common system.
