The dump refers to an area in the Animal Crossing series where players can drop unwanted items, excluding fish and bugs, for disposal. In Wild World, City Folk, and New Horizons, this feature is moved indoors and is referred to as the recycling bin.
In GCN games
In the GCN games, the dump is a large enclosed space found outside, typically in one of the northern acres. After being emptied, several random items are generated that the player can take as desired.
In Wild World & City FolkThe dump was replaced by the recycling bin in Wild World and City Folk. Town Hall, on the right side. Like the dump in previous games, the bin is emptied at 6 am every Monday and Thursday, at which point several new items will generate. Some items include furniture that neighbors have thrown away after remodeling their house. Pitfall seeds may also appear in the recycling bin.
As with the dump, trash tossed into the bin offers a means for players to dispose of trash without negatively affecting the town rating. In Wild World, the bin holds the standard fifteen items, like the player's bag, while in City Folk, it only holds twelve.
In New Leaf
Although the dump and recycling bin did not appear in New Leaf, a trashcan can be built through public works projects. This trash can however instantly disposes of items permanently as soon as they are thrown in. It does not generate free items like in previous games.
The recycling shop, Re-Tail, shares similarities with the dump feature, letting players place furniture and other items for free. These items can then be bought by villagers. Trash can be disposed of by talking to Reese, at a cost of 80 Bells.
The fence public work project can substitute as a miniature dump, as players are able to place items within its boundary. However, it does not empty or generates random items like the feature from GCN games.
In New Horizons
In New Horizons, the "recycling box" is located inside Resident Services. Various items may appear in it over time following certain events. When the box becomes full, the oldest items are discarded to make room for new items. The player can take any items from the box that they want.
The recycling box always contains a single cardboard box at the start of the game. When a new villager moves to the island and unpacks their belongings, another cardboard box can appear in the recycling box the next day. When an old villager moves out, one piece of furniture from their house will go to the recycling bin. If they were given an article of clothing by the player, they will also leave it in the recycling box for the player to reclaim. Unique articles of clothing such as the Baggy Shirt and Shattered Glasses can also be found in the recycling box. They appear in the Nook Shopping catalog but cannot be ordered. After a visit from Gulliver, a single rusted part, which is a rare crafting material, can be found in the box.
In party play mode, any item picked up by the secondary player character will appear in the recycling box to be claimed once the session is over.
