By the year 2050, the world’s population is expected to grow to approximately 9.6 billion, with approx 66% urban residents. This estimation is making people, across the world, serious to think about how they’ll feed all those people.
A Swedish food-tech firm called Plantagon is suggesting that cities consider building what it calls “plantscrapers” — office towers that include enormous indoor farms. Plantagon is creating its first plantscraper in Linköping, Sweden.
Called The World Food Building, the tower will work hydroponically, meaning vegetables (mostly greens) will grow without soil in a nutrient-rich, water-based solution. The farm will largely be automated, Plantagon CEO Hans Hassle told Business Insider.
The construction of this giant project started back in 2012 and will be open to the public by early 2020.
Scroll down to know the plans for the $40 million project:
The tower will produce nearly 550 tons of vegetables every year that is enough to feed around 5,500 people each year.
The 16-storey tower will be divided into three parts: Around two-thirds of the portion will be given to offices and the third one will be dedicated only to indoor farms.
Well, the crops will grow utilizing both sunlight and LEDs.
Most of the operations will be in the hands of robots.
The plantscraper will generate more food comparatively while using less land and water, Hassle said. He estimates the tower will save 1,100 tons of CO2 emissions and 13 million gallons of water at the end of each year.
The building will also include a market where people can buy vegetables. Local restaurants and other food retailers will be able to buy directly from Plantagon, which will operate the farm, Hassle said.
The designers believe Linköping’s plantscraper will motivate other cities around the globe to construct large-scale indoor farms that have multiple uses.
Hassle believes that more cities should grow food closer to urban centres. “This project demonstrates how to feed cities of the future when they lack land, water, and other resources,” he said.
