Ensure that the spot receives a reasonable amount of sunlight in a day. Additionally, the place should also be flat and well ventilated.

Add compostable materials: when you set up your compost bin, add the pineapple alongside other green organic materials. You need to first add brown L’s on the first layer in the compost. Add about 5 inches of greens on the first layer( that is the first layer of browns).

If you like, you can add one shovel of garden soil. This is to help introduce more decomposition microorganisms such as millipedes and earthworms.

Alternate between layers of browns and greens: after adding the first layer of brown and the second layer of greens, you need to alternate between greens and browns until the compost bin is full.
