Is algae the ink of the future? | Scott Fulbright | TEDxMileHigh
-
0:17 - 0:20I sat down to write
a talk about sustainability, -
0:20 - 0:23but then I heard an airplane.
-
0:23 - 0:26I became curious about
where it took off from, -
0:26 - 0:28where it was going,
-
0:28 - 0:31and why do only some airplanes
leave white streaks behind them. -
0:31 - 0:35As I'm thinking this, I look over
at my two-year-old son, -
0:35 - 0:37and he's pointing up at the plane.
-
0:37 - 0:41That's when I realized I have
the curiosity of a two-year-old. -
0:42 - 0:43(Laughter)
-
0:43 - 0:46And having the curiosity
of a two-year-old comes -
0:46 - 0:48with some unique challenges.
-
0:48 - 0:51When I was in high school,
I took the ACT exam, -
0:51 - 0:54and the proctor said, "Please use
a number-two pencil and begin." -
0:54 - 0:58All of my peers dropped their head
and started filling in the little bubbles. -
0:58 - 1:01I sat there, and I got curious
about what's the difference -
1:01 - 1:03between a number-one
and a number-two pencil. -
1:03 - 1:05(Laughter)
-
1:05 - 1:07I started thinking about nylon.
-
1:07 - 1:10What's it made out of,
and why is it so loud? -
1:10 - 1:14Why do humans start
to twitch when we get nervous? -
1:14 - 1:16And most importantly,
-
1:16 - 1:19why does the girl behind me
with the nervous twitch have -
1:19 - 1:21nylon swoosh pants on?
-
1:21 - 1:23(Laughter)
-
1:24 - 1:27For six hours, all I heard
was, "Shh, shh, shh, shh." -
1:28 - 1:29(Laughter)
-
1:29 - 1:33It's times like this that I've had
to contain my curiosity. -
1:33 - 1:36I must've done OK
because I got into college. -
1:36 - 1:37In my first year there,
-
1:37 - 1:41all my friends got internships
in marketing and finance, -
1:41 - 1:42but not me.
-
1:42 - 1:45I wanted to do Marine Biology -
-
1:45 - 1:47in the middle of Michigan.
-
1:47 - 1:48(Laughter)
-
1:48 - 1:51There's no whales,
dolphins, or sea turtles, -
1:51 - 1:54but there is algae.
-
1:54 - 1:58You know, algae; the plant-like organism
that grows in rivers and lakes? -
1:58 - 2:00I became curious about algae,
-
2:00 - 2:03and I got an internship
as an algal biologist. -
2:04 - 2:06I quickly learned two things -
-
2:06 - 2:10one: algae are fascinating organisms
that influence our everyday life; -
2:11 - 2:15and two: girls at college parties
loved talking about algae. -
2:15 - 2:17(Laughter)
-
2:17 - 2:21So maybe I didn't impress any girls
by being an algal biologist, -
2:21 - 2:24but I did become intrigued
with the world of algae. -
2:24 - 2:29Like plants, algae use carbon dioxide
and sunlight to produce oxygen. -
2:29 - 2:32So I want you to do me a favor.
-
2:32 - 2:33I'm going to count to three,
-
2:33 - 2:36and we're all going to take
a big inhale, and then exhale. -
2:36 - 2:38Ready? One, two, three.
-
2:38 - 2:40(Inhaling)
-
2:40 - 2:42(Exhaling)
-
2:42 - 2:47Over half the oxygen you just inhaled
was produced from algae. -
2:47 - 2:50Over half; that's insane!
-
2:50 - 2:52It's literally keeping us alive.
-
2:52 - 2:56Algae grow everywhere: on your shoes,
in your dog's water bowl, -
2:56 - 3:00definitely in your local ponds,
and on the back of this sloth. -
3:01 - 3:02(Laughter)
-
3:02 - 3:05Sorry, I just like to throw
a sloth slide in when I can. -
3:05 - 3:07(Laughter)
-
3:07 - 3:12Algae are the foundation
of the aquatic ecosystem, -
3:12 - 3:14and they come in a variety of colors.
-
3:14 - 3:16The brown, the red, and the green
-
3:16 - 3:18are just different species of algae.
-
3:18 - 3:22Here's the coolest part:
algae grow really fast; -
3:22 - 3:25so fast that scientists are trying
to domesticate algae -
3:25 - 3:28for products like biofuels
and animal feed. -
3:28 - 3:33This is a picture of a large open pond
that's growing algae cells. -
3:33 - 3:35The algae cells are extracted
from the water -
3:35 - 3:38to be made into these products.
-
3:38 - 3:40These bioproducts
have a huge potential -
3:40 - 3:42to make the world
much more sustainable, -
3:42 - 3:45and it's currently undergoing
commercialization. -
3:45 - 3:48I wanted to play a part
of this commercialization, -
3:48 - 3:49so I went to Colorado State University,
-
3:50 - 3:53and I got my PhD in the Cell
and Molecular Biology program. -
3:53 - 3:56I spent thousands of hours
in the office and in the laboratory -
3:56 - 4:00researching algae growth projects
for commercialization. -
4:01 - 4:06Then, on a summer day in 2013,
I was in the algae research laboratory -
4:07 - 4:09and my wandering mind got away from me,
-
4:09 - 4:12and I realized it was
my grandma's birthday. -
4:12 - 4:14My grandma likes a good greeting card,
-
4:14 - 4:18so I had to run out of the laboratory
to the local grocery store, -
4:18 - 4:20and I got stuck
in this greeting card aisle. -
4:20 - 4:23I became curious
about what's a greeting card? -
4:23 - 4:25It's just paper and ink.
-
4:25 - 4:27But what's ink?
-
4:27 - 4:29I looked all around me,
-
4:29 - 4:34and I realized every product,
package, and sign was covered in ink. -
4:34 - 4:37So what is ink?
-
4:37 - 4:39Ink is 80% petroleum products.
-
4:40 - 4:43Petroleum comes from places
like tar sands operations -
4:43 - 4:45where vegetation is stripped
-
4:45 - 4:47so that oil can be extracted
from the earth. -
4:47 - 4:51This devastates entire ecosystems.
-
4:51 - 4:54The other 20% of ink are pigments.
-
4:54 - 4:58Pigments are often minerals
that are mined from the earth. -
4:58 - 5:01Sometimes, they can be petroleum.
-
5:01 - 5:07For example, carbon black is the pigment
that makes your printer ink at home black, -
5:07 - 5:08and it's a known carcinogen.
-
5:08 - 5:12So not only is ink toxic
and unsustainable, -
5:12 - 5:15it's the most expensive liquid we buy.
-
5:15 - 5:18If you do the math
about your printer ink at home, -
5:18 - 5:21it's about 10,000 dollars a gallon.
-
5:21 - 5:24My curiosity kept me learning about ink.
-
5:24 - 5:26What was most fascinating to me
-
5:26 - 5:31was that a traditional ink pigment
is about the same size as an algae cell. -
5:31 - 5:32That's when I first realized,
-
5:32 - 5:36"Could we use algae
as a sustainable ink replacement?" -
5:38 - 5:41Talk about curiosity overdrive.
-
5:41 - 5:42Within three months,
-
5:42 - 5:45my best friend from graduate school
and I started a company -
5:45 - 5:48developing and commercializing
algae ink products. -
5:48 - 5:52Believe it or not, algae worked
really great as an ink. -
5:52 - 5:57And, like I mentioned earlier,
algae come in a variety of colors. -
5:57 - 6:01There's blues, reds, yellows, and so on.
-
6:01 - 6:05Nature's already developed
these cells and these colors; -
6:05 - 6:09we're just developing
new methods to use them. -
6:09 - 6:12So how do we turn algae into ink?
-
6:12 - 6:14We grow algae
in these controlled containers. -
6:14 - 6:18We then harvest the cells, meaning
that we concentrate them down, -
6:18 - 6:22and then we add plant-based components
to make the ink formula. -
6:22 - 6:27Then we can print on paper,
cardboard, and even cotton textiles. -
6:27 - 6:32So we're not extracting finite,
toxic materials from the earth; -
6:32 - 6:34we're using carbon dioxide and sunlight
-
6:34 - 6:38to literally grow our pigments
for the most sustainable ink in the world. -
6:38 - 6:40Our ink is 100% biodegradable,
-
6:40 - 6:43meaning that if you put it
in your compost pile, -
6:43 - 6:45it would degrade in a matter of days.
-
6:46 - 6:49The ink that's on your agenda
right now will never degrade. -
6:49 - 6:52We're working with some
of the biggest companies in the world -
6:52 - 6:54to develop and commercialize
this technology -
6:54 - 6:58for products like packaging ink,
marketing materials, and even pen ink. -
6:59 - 7:01We're super excited.
-
7:01 - 7:04We've developed a renewable,
sustainable, and safe ink. -
7:04 - 7:06But why stop there?
-
7:06 - 7:10We developed a second ink technology
where we use living algae cells -
7:10 - 7:14as an ink that grows over time
when exposed to light. -
7:14 - 7:17It's the world's first time-lapse ink.
-
7:17 - 7:20I'll show you a greeting card
product that we made. -
7:20 - 7:24On day one, there's a picture
of an owl, and it says, "Owl." -
7:24 - 7:29On day two, the algae cells grow,
forming another owl. -
7:29 - 7:30(Laughter)
-
7:30 - 7:34And on day three, another image
grows, and it says, "Owl always love you." -
7:34 - 7:35(Laughter)
-
7:35 - 7:37(Applause)
-
7:43 - 7:47I'll show you that
in a real-time video here. -
7:52 - 7:54We're going to take this ink
-
7:54 - 7:58and make products like greeting cards,
promotional products, and science kits -
7:58 - 8:02that will inspire
the next generation of scientists. -
8:02 - 8:03We envision a world
-
8:03 - 8:06where your cereal box is covered
in sustainable algae ink, -
8:06 - 8:10and the billboard you drive by
changes every day -
8:10 - 8:12because the ink is alive.
-
8:12 - 8:15Every once and a while, I'm reminded
-
8:15 - 8:20that this idea started
with a simple question of, "What is ink?" -
8:21 - 8:26These wandering mind inventions
are common in science. -
8:26 - 8:28Velcro was invented by a Swiss engineer
-
8:28 - 8:33who went for a walk and saw a burr
sticking to his pants and his dog. -
8:33 - 8:37Penicillin was developed
by a Scottish scientist -
8:37 - 8:40who came back from vacation
to find a type of fungus -
8:40 - 8:44killing bacteria on his dirty dishes.
-
8:44 - 8:50So curiosity taking cues from nature
have long been part of innovation. -
8:50 - 8:54So maybe a wandering mind
isn't actually a bad thing. -
8:54 - 8:59What if every once in a while,
we let our curiosity get the best of us? -
8:59 - 9:04What if we asked more questions
about our existing conditions? -
9:04 - 9:09Let's take more time
to wonder, to get curious, -
9:09 - 9:12and to let our minds wander.
-
9:12 - 9:16So I challenge you
to combine your perspective -
9:16 - 9:20with the curiosity of a two-year-old.
-
9:20 - 9:23Let your curiosity
lead you down the unknown path, -
9:23 - 9:26because you never know
where it will lead you. -
9:26 - 9:30And lastly, I believe that if we allow
our curiosity to thrive, -
9:30 - 9:32and we use nature a template,
-
9:32 - 9:36we will develop amazing innovations
to overcome the sustainability challenges -
9:36 - 9:38that we face today.
-
9:38 - 9:39Thank you very much.
-
9:39 - 9:40(Applause)

- Is algae the ink of the future? | Scott Fulbright | TEDxMileHigh
- Description:
-
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
Every day, we are surrounded by ink; it’s on magazines, newspapers, billboards, packaging, products, food, and clothes. The list is seemingly endless, but what is ink made of? Petroleum, a fossil fuel that never biodegrades. As a biologist who studies algae, Scott just might have stumbled upon a solution to this sustainability blindspot.
Scott has spent the last decade in the algae bioproducts industry, leading research and developing projects with the goal of optimizing algae growth for biofuels. In 2008, he did product development at an algae biotechnology company that raised 17 million dollars during the development phase. In 2013, he co-founded Living Ink, a company that develops sustainable ink technologies from algae. Living Ink has won several awards including the Department of Energy Cleantech Competition.
