Designers Built a ‘Biological House’ From Upcycled Grass, Straw, and Seaweed

The Danish architectural firm Een Til Een has revealed the latest step forward in sustainable housing: the world’s first “Biological House.”

The home was built using materials made from agricultural waste, including grass, straw, and seaweed, and was conceptualized in collaboration with the Danish Environmental Protection Agency. Not only is the reuse of this material healthier for the environment, it also prevents the harmful effects of burning the waste, which is what normally happens to this type of agricultural residue if there is no use for it, according to Curbed

“It sounds like science fiction that you can build a house from things such as tomato stems, straw and seaweed, which is just as durable as normal buildings and at the time has a healthy economy and complies with the rules,” Danish Environmental Minister Kirsten Brosbøl said. “However, the Biological House shows that it is possible here and now. I appreciate that way we really get some value from materials that otherwise would end up at an incineration plant.”

In addition to the agricultural waste being used for most of the raw building material—including tomato stems and woodchips being turned into composite boards—eco-friendly Kebony wood was used for the home’s outer cladding. According to Kebony, 40 partners were used in the construction of the home, each with an eye toward sustainability and environmental responsibility.

"Being part of this strategic partnership has been a real privilege,” Mona Gøtske, Country Manager Kebony Denmark, said. “[And] we are thrilled to have provided a façade solution for the world’s first Biological House that demonstrates the strength and sustainable values of Kebony in the best possible way.”

The modular home was built on screw piles, which allows it to be moved without tearing up soil the way a traditional concrete foundation would, as Inhabitat reported. Before it was unveiled, Een Til Een constructed this “Biological House” in secrecy in Middelfart, Denmark. But now that the project has been successfully completed, World Architecture News reports that the doors are open for visitors from all around the world to walk in and look upon the house that tomato stems built.

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.
