Has a student from Iceland just saved the planet from plastic pollution?
Product design student Ari Jónsson from Iceland has combined red algae powder with water to create a biodegradable bottle.
Jónsson – who studies at the Iceland Academy of the Arts – exhibited the project during this year’s Reykjavik design festival DesignMarch, which took place from the 10th to 13th March 2016.
After reading about the amount of waste plastic produced every day, the designer felt an “urgent” need to develop a replacement material.
“I read that 50 per cent of plastic is used once and then thrown away, so I feel there is an urgent need to find ways to replace some of the unreal amount of plastic we make, use and throw away each day,” said Jónsson. “Why are we using materials that take hundreds of years to break down in nature to drink from once and then throw away?”
He began studying the strengths and weaknesses of different materials to determine what could be suitable for use as a water bottle. Eventually he came across a powdered form of agar, a substance made from algae.
When agar powder is added to water, it forms a jelly-like material. After experimenting to find the right proportions, Jónsson slowly heated the substance before pouring it into a bottle-shaped mould that had been kept in the freezer.
He then rotated the mould while submerged in a bucket of ice-cold water, until the liquid inside has taken the shape of the bottle.
It was then placed in a refrigerator for a few minutes before the agar bottle was extracted from the mould.
As long as the bottle is full of water, it will keep its shape, but as soon as it is empty – it will begin to decompose.
“If it fails, or if the bottom is too thin or it has a hole in it, I can just reheat it and pour it into the mould again,” said Jónsson.
As the bottle is made from 100% natural materials, the water stored inside it is safe to drink – although Jónsson noted that after a while it may extract a small amount of taste from the bottle.
He even suggested that if the user likes the taste, they should bite the bottle itself when you have finished drinking.
Designers are increasingly experimenting with seaweed and other forms of algae. Seaweed has recently been used as architectural cladding and to create lampshades, while algae provided a base material to form a yarn for weaving rugs and a dye for colouring textiles. Algae has even been implemented as an energy source to power buildings.
Jónsson’s algae bottles were presented at the Drifting Cycles student exhibition, which was held during DesignMarch 2016 inside a remote lighthouse.

Jake Davies boards Ghazala Explorer for an unforgettable Red Sea diving experience…
Overnight, the wind picked up, making the planned morning dive a bit bumpy on the Zodiacs to the drop point on Thomas Reef. There, we would dive along the reef before descending through the canyon and then passing under the arch before ascending the wall with a gentle drift. The site provided great encounters with more pelagic species, including shoals of large barracuda, tuna, and bigeye trevally.
Once back on the boat, it was time to get everything tied down again as we would head back south. This time, with the wind behind us, heading to Ras Mohammed to dive Jackfish Alley for another great gentle drift wall dive before then heading up the coast towards the Gulf of Suez to moor up at the wreck of the Thistlegorm. This being the highlight wreck dive of the trip and for many onboard, including myself, it was the first time diving this iconic wreck. I had heard so much about the wreck from friends, and globally, this is a must on any diver’s list. Fortunately for us, there was only one other boat at the site, which was a rarity. A great briefing was delivered by Ahmed, who provided a detailed background about the wreck’s history along with all the required safety information as the currents and visibility at the site can be variable.
Kitting up, there was a lot of excitement on deck before entering the water and heading down the shoreline. Descending to the wreck, there was a light northerly current which reduced the visibility, making it feel more like the conditions that can be found off the Welsh coast. At 10m from the bottom, the outline of the wreck appeared as we reached the area of the wreck which had been bombed, as our mooring line was attached to part of the propeller shaft. Arriving on deck, instantly everywhere you looked there were many of the supplies which the ship was carrying, including Bren Carrier tanks and projectiles that instantly stood out.
We headed around the exterior, taking a look at the large propeller and guns mounted on deck before entering the wreck on the port side to take a look in the holds. It was incredible to see all the trucks, Norton 16H, and BSA motorcycles still perfectly stacked within, providing a real snapshot in time.
Overall, we had four dives on the Thistlegorm, where for all of the dives we were the only group in the water, and at times, there were just three of us on the whole wreck, which made it even more special, especially knowing that most days the wreck has hundreds of divers. Along with the history of the wreck, there was plenty of marine life on the wreck and around, from big green turtles to batfish, along with shoals of mackerel being hunted by trevally. Some unforgettable dives.
The final leg of the trip saw us cross back over the Suez Canal to the Gobal Islands where we planned to stay the night and do three dives at the Dolphin House for the potential of sharing the dive with dolphins. The site, which included a channel that was teeming with reef fish, especially large numbers of goatfish that swam in large shoals along the edge of the reef. These were nice relaxing dives to end the week. Unfortunately, the dolphins didn’t show up, which was okay as like all marine life they are difficult to predict and you can’t guarantee what’s going to be seen. With the last dive complete, we headed back to port for the final night where it was time to clean all the kit and pack before the departure flight the next day.
The whole week from start to finish on Ghazala Explorer was amazing; the boat had all the facilities you need for a comfortable week aboard. The crew were always there to help throughout the day and the chefs providing top quality food which was required after every dive. The itinerary providing some of the best diving with a nice mixture of wreck and reef dives. I would recommend the trip to anyone, whether it’s your first Red Sea liveaboard in the Red Sea or you’re revisiting. Hopefully, it’s not too long before I head back to explore more of the Red Sea onboard Ghazala Explorer.
