How This Underground Urban Farm in Stockholm Will Heat the Building Above It

In just a few months, an emerging startup in Stockholm will attempt to change how urban farmers think about sustainability—and how building owners can benefit from being eco-friendly. A Swedish company called Plantagon is expected to open a basement farm under a 26-floor office tower in the city without paying a cent in rent.

How? If all goes according to plan, the heat from the LED lights helping to nourish the plants will be vented to the rest of the building, covering heating costs that are nearly three times the amount the building’s owners would charge to lease the space.

The recycled energy is part of Plantagon’s plan to alter the landscape of urban farming. According to Fast Company’s Adele Peters, the company—which is soliciting a round of capital on the Swedish crowdfunding site FundedByMe—is looking to provide a model for farmers to host and distribute their greens while minimizing overhead. Some of the produce will be sold directly to office workers above the farm, including two restaurants; Plantagon also plans to open a store in the building as well as sell goods to nearby dealers that won’t require fossil fuels to transport.


Plantagon intends to open 10 more farms in Stockholm and one “plantscraper” (the concept art for which is shown above) that will provide food on multiple floors while subsidizing costs with tenants on others floors. Eventually, Plantagon might even be able to sell its additional heat from the farms into citywide channels to further support the cost of doing business.

Watch the First-Ever Footage of a Baby Dumbo Octopus

Dumbo octopuses are named for the elephant-ear-like fins they use to navigate the deep sea, but until recently, when and how they developed those floppy appendages were a mystery. Now, for the first time, researchers have caught a newborn Dumbo octopus on tape. As reported in the journal Current Biology, they discovered that the creatures are equipped with the fins from the moment they hatch.

Study co-author Tim Shank, a researcher at the Woods Hole Oceanographic Institution in Massachusetts, spotted the octopus in 2005. During a research expedition in the North Atlantic, one of the remotely operated vehicles he was working with collected several coral branches with something strange attached to them. It looked like a bunch of sandy-colored golf balls at first, but then he realized it was an egg sac.

He and his fellow researchers eventually classified the hatchling that emerged as a member of the genus Grimpoteuthis. In other words, it was a Dumbo octopus, though they couldn't determine the exact species. But you wouldn't need a biology degree to spot its resemblance to Disney's famous elephant, as you can see in the video below.

The octopus hatched with a set of functional fins that allowed it to swim around and hunt right away, and an MRI scan revealed fully-developed internal organs and a complex nervous system. As the researchers wrote in their study, Dumbo octopuses enter the world as "competent juveniles" ready to jump straight into adult life.

Grimpoteuthis spends its life in the deep ocean, which makes it difficult to study. Scientists hope the newly-reported findings will make it easier to identify Grimpoteuthis eggs and hatchlings for future research.

London Grocery Chain Encourages Shoppers to Bring Their Own Tupperware

Why stop at bringing your own grocery bags to the store? One London grocery wants you to BYO-Tupperware. The London Evening Standard reports that a UK chain called Planet Organic has partnered with Unpackaged—a company dedicated to sustainable packaging—to install self-serve bulk-food dispensers where customers can fill their own reusable containers with dry goods, cutting down on plastic packaging waste.

To use the system, customers walk up and weigh their empty container at a self-serve station, printing and attaching a label with its tare weight. Then, they can fill it with flour, nuts, or other kinds of dry goods, weigh it again, and print the price tag before taking it up to the check out. (Regular customers only have to weigh their containers once, since they can save the peel-off label to use again next time.)

Planet Organic is offering cereals, legumes, grains, nuts, chocolate, dried fruit, and even some cleaning products in bulk as part of this program, significantly reducing the amount of waste shoppers would otherwise be taking home on each grocery trip.

Zero-waste grocery stores have been popping up in Europe for several years. These shops, like Berlin's Original Unverpackt, don't offer any bags or containers, asking customers bring their own instead. This strategy also encourages people to buy only what they need, which eliminates food waste—there's no need to buy a full 5-pound bag of flour if you only want to make one cake.

The concept is also gaining traction in North America. The no-packaging grocery store in.gredients opened in Austin, Texas in 2011. The Brooklyn store Package Free, opened in 2017, takes the idea even further, marketing itself as a one-stop shop for "everything that you'd need to transition to a low waste lifestyle." It sells everything from tote bags to laundry detergent to dental floss.
