Compost Bin





A Compost Bin is an immovable container where weeds, crops, herbs, fruits and other Farming skill products are placed to make compost, supercompost, or rotten tomatoes. Compost Bins are located next to allotment/flower/herb patches:


 * South of Falador (Cabbage-Port Teleport)
 * West of Port Phasmatys (Ectophial Teleport)
 * North of Ardougne (Ardougne Cloak Teleport)
 * North of Catherby (Camelot Teleport)
 * Middle camp of Herblore Habitat (Juju Spiritbag Teleport)

Players need 15 items to fill the Compost Bin, which they can then close to start the rotting process. This takes approximately one hour.

Players must use 15 supercompost-compatible items in the compost bin to make supercompost - even one incompatible item will make the whole contents into regular compost. This is the same when making rotten tomatoes. A message will pop up warning the player if they choose to impurify their compost bin.

After the 15 September update, compost bins were updated so that when examined players could see how full they were, from empty through to completely full (0-15 items). Since different players fill the compost bins with different quantities of items, the examine text is different for each player depending on what they have put inside.
