The phrase "what bin is it" is commonly related to queries about identifying the correct waste or recycling bin for disposal or collection days. It typically refers to finding out which bin to use for certain types of waste (general waste, recycling, garden waste) and when the collection day is for that bin. For example:

• Some local councils provide services or websites where residents can enter their postcode or address to find out the schedule for putting out their bins.
• The bins might correspond to specific types like domestic waste, recycling, garden waste, paper, glass, cans, etc.
• It is important that waste is placed in the correct bin and out on the kerbside by the designated collection day and time.

If this question specifically concerns identifying which bin to use or when to put it out for collection at a particular location, checking the local council's waste management website or service is recommended to get precise information based on area and date.
