New carbon dioxide ventilators could turn fumes into fertilizer to bring vegetable patches to high-rise rooftops, suggests a new study. Spinach grown near the new air vents grew four times larger than the other plants, according to the findings. The breakthrough is a promising development for healthier city life.
Scientists at Boston University created new technology that turned carbon dioxide (CO2) pumped from building air vents into fertilizer to improve the challenging plant-growing conditions for rooftop plant life. Rooftop farms and gardens are an increasingly popular way of tackling poor air quality and lacking food resources in cities, but they are hard places for plants to grow.
