            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
