Snøhetta designs compostable hemp light Superdupertube

Norwegian studio Snøhetta has teamed up with lighting brand Ateljé Lyktan to create Superdupertube, an office lamp made from extruded hemp and sugarcane bioplastic.

The design is a contemporary update of Ateljé Lyktan‘s Supertube – an office light from the 1970s made from extruded aluminium.

“[The Supertube] had finished production in 2010 or something like that, so it was iconic but sort of forgotten,” Snøhetta partner Jenny B Osuldsen told Dezeen. “And it’s a tube. It’s not rocket science but it is what you need for a smart lamp in an office.”

“We really loved it and think it has a lot of possibilities, so we wanted to upgrade it to a new level,” she added.

The extrusion technique for the original lamp was developed in the 1960s, and Snøhetta and Ateljé Lyktan decided to create a lamp that would nod to the original design.

However, the aim was to lower the carbon footprint of the lamp by choosing the most sustainable material possible.

The studios played around with multiple different materials before settling on the hemp bioplastic, which was used to form Snøhetta’s first office lighting design.

Snøhetta and Ateljé Lyktan first worked together on The 7th Room, a charred-timber cabin suspended among the treetops in northern Sweden, for which they also collaborated on the lighting design.

“When we were doing The 7th Room project up in northern Sweden, everything was in pine and there were lots of pine cones,” Osuldsen said.

“We wanted to find a product or material that isn’t used for anything else, so we started testing the use of pine cones by grinding them, but it didn’t work.”

“The fibres in the cones are too short,” said Ateljé Lyktan product director Malin Gadd. “We also tried using coffee grounds but they are even shorter, so we realised quite quickly that we needed fibres that are long and strong.”

“That’s where the hemp fibres come into the picture,” she added.

Snøhetta and Ateljé Lyktan sourced the hemp used for the lights from the Netherlands, as the quality of the hemp from Swedish farmers “wasn’t quite there yet”, according to Gadd.

The hemp is mixed with a polylactic acid (PLA) bioplastic derived from sugarcane, alongside wood cellulose and different minerals to create a fossil- and gas-free composite.

The material is then extruded to create the main body of the lamp, which also comprises injection-moulded louvres and side covers. To add to the organic feel of the light, its electric cables are covered with linen fabric.

“Hemp is an old cultural plant and it’s very easy to renew [by growing more],” Osuldsen said. “And it’s very durable.”

The Superdupertube can be composted in an industrial composter or recycled and ground down into pellets to create more lamps.

However, this currently requires owners to send the lamps back to the producer, as the material cannot be processed in regular recycling centres.

Using the hemp bioplastic reduces the lamp’s carbon footprint by over 50 per cent compared to traditional aluminium variants, according to Snøhetta and Ateljé Lyktan.

The dimmable Superdupertube features twisted louvres – an architectural detail that helps the light feel softer by angling the glare away.

“That’s why it’s a perfect workspace luminaire, it’s adapted to be better for the person sitting working and it’s also totally unique – it doesn’t exist on the market,” Gadd said.

The Superdupertube, which comes in four different lengths, has an organic beige colour with a natural pattern from the hemp and other ingredients.

“We didn’t really know how it would look,” Osuldsen said. “The material is the colour of the hemp. And, of course, there’s probably something from the sugarcane because it’s heated up. It’s burnt sugar in a way.”

“So we get this specific colour and that also means that all of them will be a little bit different,” she added. “It’s all about the crops; if it’s a wet year or a dry year, the humidity in the material will be a little bit different. That’s why it’s sort of alive.”

Other recent Snøhetta projects include a glass-lined library in China designed to look like a forest and a hexagonal paving system for urban landscapes.

Evolution Music creates “ecologically sound” bioplastic 12-inch vinyl

Music and sustainability collective Evolution Music has designed a 12-inch vinyl made of bioplastic using existing record pressing machinery, which features tracks by artists Beatie Wolfe and Michael Stipe.

Hailed as the world’s first commercially available bioplastic 12-inch vinyl by Evolution Music, the product is made from specially designed bioplastic instead of traditional, carbon-intensive PVC.

The bioplastic 12-inch vinyl looks and functions like a standard vinyl, comprised of a black disc illustrated with a central graphic design.

It was manufactured using existing record pressing machinery and production processes.

Its A-side features the track Future, If Future by American musician Stipe, while Oh My Heart by British-American artist Wolfe can be played on its B-side.

The bioplastic 12-inch vinyl’s creators said that they were prompted to design the material and the product themselves after struggling to find “sustainable solutions for physical media”.

“It is a robust, ecologically secure compostable material created specifically to act and sound the same as PVC-derived vinyl,” Evolution Music CEO Marc Carey told Dezeen.

To create the bioplastic, a four-year development process involved identifying a base polymer that acts in the same way as traditional PVC, without producing harmful substances, according to Carey.

After this, the team sourced bio-organic fillers and co-created a solid additive used for plastics called a bio masterbatch.

Evolution Music’s aim was “to create a biopolymer that is authentic, truly sustainable and ecologically sound,” explained Carey.

“We’ve never developed traditional plastic vinyl – I guess you should ask the PVC manufacturers why they didn’t [create bioplastic vinyl],” he said.

Five hundred copies of the bioplastic 12-inch vinyl were initially sold when it was released earlier this year, with the proceeds donated to the charity EarthPercent.

Founded by musician Brian Eno, EarthPercent invites artists to pledge a portion of their income to the charity, which is then donated to organisations that tackle climate change.

The release of the bioplastic 12-inch vinyl forms part of a Bandcamp project by EarthPercent that includes over 100 tracks by artists including Hot Chip, Peter Gabriel and Nile Rogers.

“It took three passionate, independent music lovers from the UK to develop this product out of necessity,” concluded Carey.

“The fact that ‘big’ players did not do this in the first place raises interesting questions about the petrol, chemical, oil and plastics industry… just saying!”

Other recent bioplastic designs include a clingfilm alternative made from waste potato peels and a polystyrene substitute created from plastic-eating mealworms.

Wind turbine bioplastic can be recycled into gummy bears

Spotted:  While wind power currently represents 6 per cent of global electricity production, one major obstacle to overcome is the disposal of decommissioned turbines. Most turbine blades are made of fiberglass, which is difficult to recycle. As a result, tens of thousands of discarded blades find their way into landfills every year. Now, Michigan State University may have found a solution to this problem. Researchers there have developed a new turbine blade material that can be easily recycled at the end of its life span. 

By combining glass fibres with a plant-derived polymer and a synthetic one, Dr. John Dorgan, Ph.D., and colleagues have developed a thermoplastic resin that can be recast into new products.

To recycle panels made from the new resin, the team dissolved the used composite in fresh monomer, physically removing the glass fibres. They were then able to recast the material into new composite sheets, making new blades with the same physical properties as their predecessors.

In addition, the team’s work suggests that other applications for recycled carbon fibre composites may be possible. For example, the researchers found that digesting the resin in an alkaline solution produced potassium lactate, which is commonly used in sweets and sports drinks. The potassium lactate could even be used to make the gummy bears beloved by children around the world.

“The beauty of our resin system is that at the end of its use cycle, we can dissolve it, and that releases it from whatever matrix it’s in so that it can be used over and over again in an infinite loop,” explains Dorgan, representing the team at the fall meeting of the American Chemical Society (ACS).

The next step is for the researchers to build test turbine blades using the material. As for potential food-grade uses, the question is whether the public will be willing to eat something that was once used for such a clearly non-edible application. Dorgan’s response is that a carbon atom is a carbon atom regardless of where it comes from.

As wind turbines become more prevalent and the problem of their disposal becomes more apparent, Springwise has covered other methods for recycling wind turbine blades. These include a recyclable composite innovation turning turbine blades into snowsports equipment, and the UK’s first turbine blade recycling project.
