The compost bin allows you to turn compostable materials into Mulch, which acts like soil. It has a meter indicating how much compost material it contains, as well as a 5x5 inventory grid where mulch is outputted. The compost bin holds approx 300 units of compost. Worms can also be placed in the inventory to speed up the process.
