The colour black is everywhere. From our phones to our cars to the ink in our pens. But black has a dark side. Every black thing you own is likely to contain carbon black – a pigment derived from petroleum. The way carbon black is made isn’t sustainable. Vast tracts of land called tar sands are stripped of all life and vegetation to extract the heavy petroleum, while the production process creates significant greenhouse gases.

So we’re on a search for the new black. And our aim is to reinvent the way in which the colour itself is made using black algae. You don’t have to dig up the Earth to find black algae. It grows in ponds using sunlight and carbon dioxide. Not only does algae generate more than half the oxygen on Earth, but once it becomes part of this sweatshirt, it captures and stores the carbon it used as its fuel for the next 100 years.

Black algae and hemp are nature’s most futuristic materials

If scientists invented two new materials that could produce over half the oxygen in the world, and clean up soil and air after nuclear meltdowns – all whilst sucking up carbon dioxide – it would be hailed as a miracle. But algae and hemp both do it for free. And over the next decade they’re also going to reshape how clothing and colour itself are made. So as we continue on our journey of building clothing from the materials that will shape our planet’s future, algae and hemp are as high up the list as you can get. And it’s why our Black Algae Sweatshirt is made entirely out of them.

What is carbon black?

With the Black Algae Sweatshirt we’re going back to the very start of the supply chain to take on a harmful and pervasive pigment known as carbon black. Unless you’ve spent your life on a desert island with no clothes and no possessions, you’ll run into carbon black every day. It’s in the ink in your black pen, your black phone case, and the tyres on your car. Carbon black is the pigment that’s used to make black things black. But we don’t question where it comes from because very few people know it’s even there.
Making the colour black hasn’t changed for 100 years

The way carbon black is made hasn’t really changed for over a century. At mass scale the process begins with a fossil fuel like heavy petroleum which is fed into an industrial furnace and allowed to partially combust. This creates a black powder that looks a bit like soot. And this is carbon black. It’s then used to colour everything from inks, to plastics, to rubber, and you’ll find it everywhere on the planet.
Why we’re looking for alternatives to carbon black

There are lots of problems associated with carbon black. The manufacturing process creates greenhouse gases which are released into the atmosphere. And the heavy petroleum needed to make it comes from places known as oil sands, or tar sands. These are barren areas of our planet that are stripped of all vegetation so that oil can be extracted from the ground. And as ecosystems are eroded more carbon is emitted.

We’re working with a US biomaterials startup

With the help of US biomaterials company Living Ink, we’ve found a method of making our sweatshirt without using any carbon black. After their founders Scott and Steve discovered that an algae cell is almost identical in size to a carbon black pigment, and can create the same colour, they’ve been on a mission to replace carbon black ink with a black ink made from black algae waste.

Our algae is grown in giant ponds

The algae we use starts life in huge open-air ponds where it grows by feeding on sunlight, carbon dioxide, water and nutrients. These ponds contain vast quantities of spirulina algae which absorb carbon dioxide and pump oxygen back out into the atmosphere. While the majority of the algae is used to make natural food colourings, the rest of the algae is harvested and used as the base for black algae ink.
A thermo treatment turns the algae into ink

After it’s harvested, the algae by-product is heat treated to concentrate it into a black powder which we use as pigment. This treatment seals in carbon dioxide which has been absorbed by the algae during its lifespan, preventing it from making its way back into the atmosphere. The black powder is then purified and mixed with a water-based binder to create black algae ink.
Printed with black algae ink

We print the entire outer surface of the sweatshirt with black algae ink – turning the sweatshirt a dark grey. The ink has been engineered to be UV resistant so it holds its colour for years. But as it’s bio-based and printed on hemp it won’t behave exactly like a petroleum-based ink. Over time the black colour will brighten around the edges next to the seams as it ages.

Built with carbon capture technology

Once the sweatshirt has been built and printed, the black algae ink continues to lock in the carbon dioxide that it absorbed when it was alive. And it will do this for over 100 years. So the sweatshirt you’re wearing is storing carbon emissions. This is known as carbon capture technology and it means that rather than producing emissions, the Black Algae Sweatshirt does the exact opposite.

We’ve combined black algae with hemp

The Black Algae Sweatshirt is really a story about two different technologies. While the first is obviously algae. The second is one of the most extraordinary plants on Earth – hemp. Over the last 80 years hemp has been one of the most misunderstood and badly treated materials on the planet. It’s been banned by governments, had war declared against it, and been accused of bringing down modern society. But its ancient past shows it could have a very different future.

Seven US presidents smoked it

At one time, hemp was the solution to almost any problem. Leonardo da Vinci painted the Mona Lisa on hemp canvas – the word canvas comes from cannabis. Early presidential letters indicate that at least 7 presidents, including George Washington and Thomas Jefferson, smoked it. And one of Henry Ford’s most cutting-edge cars was almost entirely built out of hemp and ran on hemp fuel, leading Mechanical Engineering magazine to call hemp “the most profitable and desirable crop that can be grown”.
Today hemp is a plant with a PR problem

But then things went sideways. The petrochemical, pulp-paper and nylon industries – who all stood to lose billions of dollars if the commercial potential of hemp was realised – campaigned against it. Propaganda, conspiracy theories and drug hysteria kicked in soon after, and hemp’s position as the wonder plant of the future took a beating with headlines like “Marihuana: The Assassin of Youth” and “Sex-Crazing Drug Menace.”
War was declared on hemp

In 1937 Roosevelt passed the Marihuana Tax Act effectively making hemp pointless to grow because it was so expensive. And by the 1970s the DEA’s war on drugs was funding a program to crop dust fields of hemp with paraquat, a chemical herbicide known to cause irreversible kidney damage, respiratory failure, and death.
Hemp is on a comeback

By the mid 80s the only two hemp products you could buy legally in the US were Hungarian twine and sterilised bird seed. But conservationists lobbied for its return, citing its huge economic and environmental benefits. The UK and Germany resumed commercial production in the 1990s. In 2013, farmers in Colorado harvested several acres of hemp, bringing the first hemp crop to the US in over 50 years. And today at least 47 US states have enacted legalisation to establish hemp production programs or allow for hemp research.

Hemp is a high-performance material

With advances in man-made materials, and the myth and misconception that surrounds everything associated with cannabis, hemp’s unique properties could easily be forgotten. But they shouldn’t be. From an environmental perspective every tonne of hemp produced removes 1.6 tonnes of CO2 from the air. It kills weeds, purifies soil, grows super-fast and will thrive almost anywhere in the world. It requires zero pesticides and very little water to cultivate. And it’s so smart scientists now use it to clean up soil, water and air contaminated with radioactive isotopes after nuclear meltdowns.

What the sweatshirt feels like

The Black Algae sweatshirt is soft and easy to wear. The fabric’s fibres are hollow – just like you get with other natural fibres like Merino – so it traps pockets of air to keep you warmer in winter, but it also allows the sweatshirt to breathe easily in summer. We’ve blended our organic hemp with organic cotton grown in the same mountainous region to make it even softer. And it’s this mix that makes the sweatshirt so comfortable.
You can wear it all day long

Because hemp fibre is porous, it’s naturally highly breathable and moisture-wicking, so it’s easy to wear all day. It can absorb up to 20% of its own weight while still feeling dry. It’s also antibacterial, so if you want to smell good all day long, hemp is the perfect choice. It blocks UV-A and UV-B rays. And thanks to its high resistance to ultraviolet light, it won’t disintegrate from sunlight like other natural fabrics.
Irrigated with mountain rainwater

We source our hemp from the most northerly province in China, Heilongjiang, working with a partner committed to producing materials sustainably. The region is known for its remote mountain ranges which supply farmlands with clean rainwater. They use this rainwater to irrigate the hemp fields, which reduces water consumption and leads to a stronger and smoother hemp plant. And that leads to a stronger and smoother sweatshirt.

Making clothes like our ancestors made them

While most industries can be improved by heading forwards as fast as possible, one of the biggest advances clothing can make is by heading backwards a few thousand years to when our ancestors were making clothes from grass, tree bark, animal skins and plants. Today we’re trying to get back to using nature to make clothes that require as little energy as possible and leave almost no trace of their existence at the end of their lives. And this means breaking apart many of the standard processes used in the industry today.

Our hemp is incredibly soft yet strong

50,000 years ago early man understood the power of hemp and used it to spin the first ever fibre. With 4x the durability and 8x the tensile strength of cotton, the Egyptians then used it to haul rocks around when they were building the pyramids. The Vikings relied on hemp ropes, sails, and nets for their voyages. Chinese warlords built their armour from it. Christopher Columbus’s voyage to the New World in 1492 was made possible thanks to the strength of his hemp sails – in fact he was so concerned about getting stranded in whatever distant land they reached, he loaded his ships with hemp seeds in the case they needed to grow more sails.
