Can you Compost Pineapple? Is It Compostable?

Composting can be incredibly beneficial for the environment, but can you compost pineapple? Unfortunately, it can be more complicated than you may think. Pineapple can be a composting “loose cannon” for three reasons:

  1. It’s acidic.
  2. It’s high in sugar.
  3. It has a tough core, peel, and leaves.

Pineapple is acidic

The acidity can stress the microbial life in your compost pile, potentially killing off organisms that can break down other materials.

The pineapple has pH levels that can range from 3.2-4.5, making them too acidic for some compost piles.

A small amount of pineapple can be OK but it can become an issue if you have larger amounts.

Pineapple is high in sugar

Pineapple is mouth-wateringly sweet but can be a problem for composting.

Sugar creates an environment where bacteria can thrive and cause anaerobic conditions, resulting in a smelly compost.

The sugary content can attract pests and can cause the compost to become slimy or sour.

If you’re adding pineapple to your compost, be sure to mix it with other materials that can balance out the sugar content.

Pineapple has a tough core, peel, and leaves

The core can be difficult for some organisms to break down and can take a long time to decompose.

The peel can turn your compost into an unappetizing mush, and the leaves can be sharp and can irritate the microbial life in your compost.
