Entomologist Neil Birrell's job title is 'maggot wrangler in chief'!
His business Hexacycle uses the larvae (aka maggots) of the black soldier fly to eat food waste and reduce the amount of food ending up in landfills (and the methane produced while it decomposes).
These maggots can also be eaten by animals and used to produce biofuel.
The project has moved from Neil's backyard, via a University of Auckland social entrepreneurship award, to India's first fly treatment plant in the south-western state of Kerala where the maggots process 1.5 tonnes of food waste every day.
