Commercial pineapple skin waste typically ends up being composted, or even just dumped in landfills. According to new research, however, a feed additive made from powdered skins has been shown to help farmed tilapia fish avoid infections, plus it reportedly boosts their growth.

According to scientists at Russia's RUDN University, pineapple skins are rich in fiber (particularly pectin) and protein. With these qualities in mind, a team led by Assoc. Prof. Morteza Yousefi started by drying out pineapple skins, then grinding them into a powder which was added to commercial tilapia feed.
