Several years ago a Swedish-American company called Plantagon unveiled plans for a series of massive skyscraper greenhouses that stood to transform urban farming in large cities. While the spiraling vertical farms seemed too good to be true at the time, Plantagon just broke ground on its very first vertical farm this week in Linkoping, Sweden! The “Plantscraper” will grow and supply fresh vegetables while creating solutions to some of the most vexing city pollution issues.
Plantagon seems to have traded in its initial geodesic dome design for a sheer tower that both contains and showcases the plants growing inside. This prototype building will be called the International Centre of Excellence for Urban Agriculture, and it will be a place for scientists to test new technologies aimed at improving urban farming.
Inside the massive glass walls, vegetables will be grown in pots and then transitioned to trays positioned around a giant central helix. The plants grow as the trays slowly migrate down the central core and are ready to be harvested once they reach the bottom. Plant residue and manure will be collected along the way and transformed into biogas to run the heating and cooling systems of the greenhouse. Scientists want the vertical farm to not only grow food but also help in developing sustainable solutions for energy, heat, waste, and water issues of daily city life.
Construction on the company’s first enormous vertical greenhouse is expected to take 12 to 16 months.
