Singapore: ‘Closed loop’ urban farm in Queenstown tackles food waste with insects

The farm currently produces around 150kg of vegetables and fish a month, and goes through the same weight of food waste a day for its insect farm, which currently houses about 10kg of the black soldier fly’s pupae.

As the Government ramps up efforts to reduce food waste and raise awareness of the problem, one urban farm in Singapore has been trying to lighten this load with the help of an insect.

Set up earlier this year, Citizen Farm in Queenstown has been using the black soldier fly to help grow its vegetables, as food for its fish and to help tackle food waste – the first in Singapore to incorporate these insects as part of farming practice.

The “closed loop” farm runs on a circular economy approach, by feeding the insect larvae with food waste from restaurants and supermarkets, turning this into nutrient-rich fertiliser.

Once the larvae transform into pupae, the insects are fed to jade perch fish which the farm rears. The fish subsequently secrete waste that becomes fertiliser for its vegetables.
