Can pineapple scraps go in your worm bin?
Pineapple peels, cores, and small amounts of fruit scraps are allowed in the worm bin with necessary caution. They contain fibers and natural acids that can slow down breakdown and, in overly large quantities, affect the worm environment. The crown, the hard, leafy top, is not suitable because it breaks down very slowly. Pineapple is also moist and sugary, which requires management.
How much pineapple can you add?
Add pineapple waste (peel, core) very limitedly. Think of small quantities, not too often, and always in proportion to the total content of your Bonter. Due to the slow breakdown and the acids, it is essential to compensate this waste with a generous amount of ‘brown’ material (shredded cardboard, paper). This not only helps with moisture balance but also buffers acidity. Keep an eye on your bin; if you see pineapple piling up, add no more.

What to do instead? Alternatives & waste management
Due to the challenges with pineapple waste in a worm bin, alternative processing methods are often a better idea. Pineapple peels and cores can go on a traditional compost heap, where they have time to break down, although breakdown can also be slow there. The hard crown is best suited for the organic waste bin (if available). For leftover pineapple flesh, consider freezing it or processing it quickly in dishes to prevent waste.

Tips for safe pineapple composting
The key to composting pineapple waste in your Bonter is preparation. Cut the peel and core into the smallest possible pieces – truly small! – to increase the surface area for breakdown. Mix these small pieces directly with a large amount of dry ‘brown’ material (paper, cardboard). Bury the pineapple waste deep under the top layer of your bedding. This helps keep fruit flies, attracted by the sugars and smell, away and limit any odors. The crown should never go in the worm bin. Thanks to the Bonter air filtration system, odors are less of a problem, but stalled breakdown of pineapple can cause local odor in the bin.
