Powder made from pineapple waste is a superfood for fish. Forget salmon or beef tenderloin: pets can get all the nutrients they need from soldier fly larvae.
And so can livestock. Up until now soldier fly larvae have been predominantly reared on starchy chicken feed.
Still, thought a Danish research team, why not experiment with an organic waste product that is available worldwide? That is, waste from breweries.
It, after all, is made up of 70% roughage, around 20% protein and 10% vitamins and minerals. Tests showed that larvae were not particularly picky.
With metabolic performance similar to a group reared on chicken feed, the larvae converted brewery waste into equal amounts of larval biomass.
Time for a new beer.
