During and shortly after the Chinese New Year period, most major banks have collection boxes as well as some companies. 

Info: 

We've mapped out all the locations found on the links above to make it easier to find the nearest red-packet recycling bin near you.  

If you do not find a bin at the location indicated, please approach the bank staff. They may be in the process of swapping out full bins.

OCBC told us: “While the bin is being replaced, you may pass the red packets to our service ambassadors in the meantime.”

Read more about why you should use these bins instead of normal paper recycling here.
