Big Waster 
Environment and Ecology Bureau
In brief, NCW means waste that is neither wrapped in a designated bag nor affixed with a designated label under "charging by designated bags/ designated labels".
For example, when a designated bag is used to dispose of waste, the waste concerned may be deemed as NCW if the bag is not tightly fastened, or if the waste is allowed to pierce through the bag.

Besides, any oversized waste (for example large furniture such as dining tables, bookshelves or mattresses) that cannot be properly wrapped in a designated bag will be considered a NCW if it is not affixed with a designated label when being disposed of.
Designated bags and designated labels will only be sold at the authorised retail outlets. Members of the public should purchase designated bags and designated labels at authorised retail outlets or online platforms.
The EPD has published notice in the Gazette to stipulate the specifications for designated bag/ label, including their sizes, shapes, designs and materials for easy reference by the public on their authenticity. Each designated bag and designated label comes with anti-counterfeit features.
