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
 * West of Port Phasmatys (Ectophial teleport)
 * North of Ardougne
 * North of Catherby (Camelot Teleport)
 * Middle of Taverley, Next to the potato patch.

Players need 15 items to fill the Compost Bin, which they can then close to start the rotting process.

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.

Compost generally takes between 35-50 minutes to decompose inside the bin.
