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.

Whether you are a beginner or a professional diver – with the three new main regulators from DYNAMICNORD, everyone will find their favourite regulator. They all look super stylish.
Excellent performance with the TR-80
Quality and performance are the be-all and end-all for regulators. It is not for nothing that the TR stands for Tec Reg. The innovative design of the TR-80 guarantees absolute reliability – even in ice-cold waters.
Perfect breathing effort at 0.8 J/l / certified for diving in waters below 10 degrees / structural design made of solid brass for best cold protection / membrane-compensated design with dry seal of the first stage / reduced exhalation effort thanks to optimized exhalation membrane and bubble deflector / adjustable Venturi (dive/predive) and adjustment knob for individual inhalation comfort / innovative design of the front cover prevents free-flow in strong currents or when diving with scooters / design made of sandblasted brass, matt chrome finish / 2 HP and 4 LP outlets / mouthpiece made of high-quality, anti-allergic silicone for maximum comfort.
Amazing underwater adventures with the IR-50
The IR-50 is the top regulator for advanced and experienced divers. Natural breathing is the essence of this regulator.
Ideal breathing effort at 0.8 J/l /certified for diving in waters below 10 degrees / compensated membrane / adjustable venturi (dive/predive) and adjustment knob for individual inhalation comfort/ outlet valve and deflector for minimum exhalation effort and reduction of bubbles on the face / design made of sandblasted brass, matt chrome finish / 2 HP and 4 NP outlets / mouthpiece made of high-quality, anti-allergic silicone for maximum comfort.
The Workhorse – our CS-30
For diving centres and diving beginners – the workhorse stands for strong construction, reliability and robustness. Perfect for your training.
Optimal breathing effort at 0.8 J/l /recommended for diving in waters above 10 degrees / non-compensated piston / adjustable venturi (dive/predive) / outlet valve and deflector for minimum exhalation effort and reduction of bubbles on the face / design made of sandblasted brass, matt chrome finish / 1 HP and 3 NP outlets / mouthpiece made of high-quality, anti-allergic silicone for maximum comfort.
Octopus OP-30
The OP-30 is the ideal addition to all DYNAMICNORD regulators. It is identical in construction to the CS-30.

Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.
The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.
Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.
In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.
Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.
Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.
The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.
Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.
Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.
