Introduction
Our sustainability project centred on diminishing the carbon
footprint of an aquaponics farm situated at Neo Tiew Road,
Singapore, currently managed V-plus Agritech Pte Ltd
(V-plus Agritech). The farm is designed primarily to utilise
sunlight, nutrients, and circulating water to cultivate fresh
vegetables and fish. Spanning approximately 1,000 sq ft of
land, the farm, erected in 2021, comprises 16 aisles of vertical
planting towers positioned atop enclosed aquaculture
systems (Figure 1).
The farm converts fish waste into an organic plant nutrient
source using nitrifying bacteria. Subsequently, these
nutrients are conveyed by circulating water, that traverses
through vertical planting towers, via a filtration pump Figure 1: The integrated aquaponics farm engaged
