Vaxa bathes microalgae in a pink-purple gentle

Within the shadow of Iceland’s largest geothermal energy station, a big warehouse homes a hi-tech indoor farm of kinds that’s like nothing I’ve ever seen.

Underneath a wierd pink-purple glow, illuminated panels buzz and cylindrical columns of water bubble away, as a futuristic crop of microalgae grows.

It is right here that Iceland’s Vaxa Applied sciences has developed a system that harnesses vitality and different assets from the close by energy plant, to domesticate these tiny aquatic organisms.

“It is a new mind-set about meals manufacturing,” says basic supervisor, Kristinn Haflidason as he offers me a tour of the space-age facility.

For a lot of our historical past, people have consumed seaweed, additionally know as macroalgae.

However its tiny relative, microalgae has been a much less frequent meals supply, though it was eaten for hundreds of years in historical Central America and Africa.

Now scientists and entrepreneurs are more and more exploring its potential as a nutrition-rich, sustainable meals.

About 35 minutes from the capital Reykjavik, the Vaxa web site produces the microalgae Nannochloropsis, each as meals for individuals, and for feed in fish and shrimp farming.

It additionally grows a sort of micro organism referred to as Arthospira, also called blue-green algae, because it shares related properties with microalgae.

When dried out it is know as spirulina and is used as a dietary dietary supplements, a meals components, and as a bright-blue meals colouring.

These tiny organisms photosynthesise, capturing vitality from gentle to soak up carbon dioxide and launch oxygen.

“The algae is consuming CO2, or turning the CO2 into biomass,” explains Mr Haflidason. “It is carbon detrimental.”

Vaxa’s plant has a novel scenario.

It is the one place the place algae cultivation is built-in with a geothermal energy station, which provides clear electrical energy, delivers chilly water for cultivation, scorching water for heating, and even pipes throughout its CO2 emissions.

“You find yourself with a barely detrimental carbon footprint,” says Asger Munch Smidt-Jensen, a meals know-how marketing consultant at Danish Expertise Institute (DTI), who co-authored a research assessing the environmental impression of Vaxa’s spirulina manufacturing.

“We additionally discovered a comparatively low footprint, each by way of land and water use.”

Round the clock renewable vitality, plus a stream of CO2, and vitamins with a low carbon footprint, are wanted to make sure the setup is climate-friendly, and he thinks that isn’t simply replicated.

“There’s a enormous enter of vitality to run these photo-bioreactors, and you need to artificially simulate the solar, so that you want a excessive vitality gentle supply,” he explains.

“My essential takeaway is that we should always utilise these areas [like Iceland] the place we’ve got low impression vitality sources to make vitality intensive merchandise,” provides Mr Munch Smidt-Jensen.

Again on the algae plant, I climb onto an elevated platform, the place I’m surrounded by noisy modular items referred to as photo-bioreactors, the place 1000’s upon 1000’s of tiny pink and blue LED lights gas the microalgae’s development, instead of daylight.

They’re additionally provided water and vitamins.

“Greater than 90% of the photosynthesis occurs inside very particular wavelengths of pink and blue gentle,” explains Mr Haflidason. “We’re solely giving them the sunshine that they use.”

All of the situations are tightly managed and optimised by machine studying, he provides.

About 7% of the crop is harvested every day, and quickly replenished by new development.

Vaxa’s facility can produce as much as 150 metric tonnes of algae yearly, and it plans to develop.

Because the crops are wealthy in protein, carbohydrate, omega-3s, fatty-acids, and vitamin B12, Mr Haflidason believes rising microalgae this fashion, might assist deal with international meals insecurity.

Many different firms are betting on the potential of microalgae – it is estimated the market shall be value $25.4bn (£20.5bn) by 2033.

Danish start-up Algiecel has been trialling moveable transport container-sized modules that home photo-bioreactors, and which might hyperlink as much as carbon-emitting industries to seize their CO2, whereas concurrently producing meals and feed.

Crops are additionally being utilized in cosmetics, prescription drugs, biofuel and a substitute for plastic.

Maybe additionally microalgae might be produced in house.

In a challenge funded by the European Area Company, the Danish Technological Establishment plans to check if a microalgae will be grown on the Worldwide Area Station.

Regardless of all of the funding, there’s some technique to go earlier than micro-algae develop into an on a regular basis a part of our weight loss program.

It nonetheless wants a variety of growth, in accordance with Mr Munch Smidt-Jensen.

He factors out that the feel lacks firmness. In the meantime the style will be “fishy” if the algae is a saltwater selection.

“However there are methods of coming overcoming this,” he provides.

There’s additionally the societal query.

“Are individuals prepared for it? How can we make it so that everybody needs to eat this?”

Malene Lihme Olsen, a meals scientist at Copenhagen College who researches micro algae, says its dietary worth wants extra analysis.

“Inexperienced microalgae [chlorella] have a really sturdy cell wall, so it may be tough for us to digest and get all of the vitamins,” she says.

For now she says microalgae is best added to different “service merchandise” like pasta or bread to assist with style, texture and look.

Nevertheless, Ms Olsen believes microalgae are a promising future meals.

“When you evaluate one hectare of soy in Brazil, and picture we had one hectare of algae subject, you could possibly produce 15 occasions extra protein a yr [from the algae].”

Inexperienced sludge anybody?

Again on the plant I am taking a look at an unappetising inexperienced sludge. It is the harvested microalgae with the water squeezed out, prepared for additional processing.

Mr Haflidason provides me a style and, after preliminary reluctance, I strive some and discover its flavour impartial with a texture like tofu.

“We’re completely not proposing that anybody ought to eat inexperienced sludge,” jokes Mr Haflidason.

As an alternative the processed algae is an ingredient for on a regular basis meals, and in Reykjavik one bakery makes bread with Spirulina and a gymnasium places it in smoothies.

“We’re not going to vary what you eat. We’re simply going to vary the dietary worth of the meals that you just eat,” he says.
