Taisugar Circular Village is Taiwan's first residential building to embrace the circular economy. From planning, designing, construction, to operation, the village carries out the "4+1 circulation," including material (precasting, modularization, and dry construction), energy (solar panels and heat pumps), water (rain and reclaimed water recycled back to the canopy farm), and food (food waste composting), plus the business model of "renting instead of buying." The building materials and resources can be continuously reused, recovered, and repaired to achieve resource circulation, low energy consumption, and zero waste in the village.
