This Japanese Startup Is Innovating with Crab Shells



A potentially valuable resource from the Sea of Japan has been ending up on the trash heap: crab shells. Now, researchers at a university in coastal Tottori Prefecture are taking the shells off of the trash heap and putting them to high-tech use.

Tottori is Japan’s crabbing capital. According to the Fisheries Agency, local fishermen brought in around 9,700 tons of the crustaceans in 2014 — nearly half of the country’s total catch.

And now researchers at Tottori University have figured out how to turn the shells into nanofibers. The plan is to establish a startup, possibly by this spring, that will seek to commercialize the technology for use in beauty and food products. If the university pulls it off, it could be the start of a whole new regional industry.

Tourists visiting Tottori set their sights on snow crabs, a delicacy, as well as the area’s famous sand dunes, shrines, hot springs and fruit. The species used for canning and in processed foods is red snow crab. In fact, more than 90% of the crabs caught in Tottori are red snow crabs. After the crabs are processed by the local fishing industry, the shells are discarded as trash.

Tottori University Associate Professor Shinsuke Ifuku was looking for ways to effectively utilize crab shells to make use of the region’s bounty, and he hit upon the concept of developing a new material in Tottori.

Ifuku studied under Professor Hiroyuki Yano of Kyoto University, one of the leaders in plant-derived cellulose nanofibers (CNF). This background led him to conceive of creating a nano-material by unraveling chitin, a substance that makes up 20-30% of crab shells. He calls the result “marine nanofibers.”

Chitin is a natural material that is used as an additive in diet foods, among other applications. The key feature of marine nanofiber is that the chitin is made into a nano-material. Water is added to chitin from the crab shells, along with an acid to make it easier to unravel the chitin, and is made finer using equipment that works like a mortar and pestle. This process is repeated until it produces a dispersion liquid of fine fibers an average of 6nm in width.

There is also a method of creating fibers by slamming the dispersion liquid containing chitin onto a substrate at high speed, but this is expensive in terms of energy and labor, costing around 20,000 yen ($170) per kilogram of dispersion liquid with a 2% concentration. Using the mortar and pestle process, Ifuku anticipates that “if economies of scale are achieved, a sales cost of just 3,000 to 4,000 yen per kilogram can be realized with a dispersion liquid having a concentration of 1-2%.”

With the objective of low-cost production in sight, Ifuku will launch a university-backed venture as early as March. The startup will procure chitin produced locally from crab shells, using equipment at the university to process it into nanofibers “having a high potential as cutting-edge materials,” and sell it.

Chitin, from which the nanofibers are made, does not mix with water in powdered form, but processed with the acid, the nanofibers repel each other, become long and thin, and then mix with water, achieving a gel-like state. It then has the same properties as CNF, for example increasing strength when included in film. However, “as we considered this deeply, we sensed that we would be unable to cultivate demand if we pitched it as the same as CNF,” Ifuku explained.

CNF is material made from wood and has five times the strength of steel while weighing just one-fifth as much. Nippon Paper Industries can turn out 30 tons of CNF a year and will raise that more than 10-fold in fiscal 2016. Chuetsu Pulp & Paper will also begin mass production in fiscal 2017. The material is priced at 5,000 to 10,000 yen per kilogram, but in terms of aspects such as stable supply, marine nanofibers, while just at the research stage, will only be playing second fiddle to CNF, which is already at the mass production stage.

One idea is products for application in the healthcare field. Although the mechanism is not well understood, it is known that chitin is effective in treating skin irritation, as well as cuts and burns.

Ifuku confirmed the effect by applying a dispersion liquid of marine nanofibers to mice with cuts in their skin. Eight days later, the cuts on untreated mice had not healed, but in the mice that had been treated with the liquid, the cuts had healed, the scabs had already fallen off and the collagen component of the skin had increased.

When compared to powdered chitin, the nanofibers have greater surface area and adhere more readily to the skin. The ability of the dispersion liquid to spread the nanofibers uniformly over the skin could be one reason for the result. When the material is applied to human skin, a film forms, producing a moisture-retaining effect.

In the foodstuffs field, the new material is being considered as a possible additive in bread. The reason bread rises is that the gluten in flour acts as a wall, allowing air to build up inside. Adding marine nanofibers reinforces the gluten walls, making it possible to reduce the amount of flour by 20%. The result is low-calorie bread, commercialization of which is being hastened.

In September 2015, Asahi Food & Healthcare commercialized a moisturizing lotion containing marine nanofibers. Following this first step, Ifuku is accelerating commercialization efforts by launching the startup. In addition, he said, joint research aimed at commercialization is being conducted with around 10 chemical and food producers.

Women on Top in Tech – Dawn Dickson, Founder and CEO of PopCom, Inc. and Founder of Flat Out of Heels



(Women on Top in Tech is a series about Women Founders, CEOs, and Leaders in technology. It aims to amplify and bring to the fore diversity in leadership in technology.)

Dawn Dickson is the Founder and CEO of PopCom, Inc. (formerly Solutions Vending, Inc.), the company behind PopCom Kiosks and the PopCom API, which provides a software solution to make vending machines more intelligent. She created the company after her own struggles to find vending machines that could sell her roll-up flat products, Flat Out of Heels, at high-traffic areas like airports.  She was awarded First place in the PowerMoves NOLA Big Break pitch Competition and second place in the 2016 SBA Innovate Her Challenge.

What makes you do what you do? 
I love solving big problems and working with amazing people to get it done.

How did you rise in the industry you are in?
After working in the vending industry for three years selling Flat Out of Heels in vending machines in airports and nightclubs, I was frustrated with the lack of data I was able to collect from my hardware. I also wanted more engaging and interactive experiences for my customers and after speaking with several retailers they felt the same way. That is when I decided to focus on PopCom and developing a software solution to solve the data problem in self-service retail.

Why did you take on this role/start this startup especially since this is perhaps a stretch or challenge for you (or viewed as one since you are not the usual leadership demographics)? 
The fact that I am not the usual, leadership demographic is the main reason why I was up for the challenge. The industry is in need of a change and I believe someone with a unique and different perspective and experience is needed. I look forward to collaborating with the industry leaders and veterans to build a product that everyone loves and finds value in.

Do you have a mentor that you look up to in your industries or did you look for one or how did that work? How did you make a match if you did, and how did you end up being mentored by him/her?
I am involved in several different industries and sectors – retail, self-service retail, hardware, software…so I have to learn a lot of information quickly.  There are several people that I look up to, follow their career, and seek advice from. I was fortunate to be able to participate in some of the country’s top accelerator and entrepreneurship development programs, including Techstars, Canopy Boulder, and the BIxel Exchange – the mentorship and network I gained from these programs has been invaluable and very instrumental in our progress.

Now as a leader how do you spot, develop, keep, grow and support your talent? 
I have learned that spotting talent takes time, it takes patience, and building relationships with people and networks to meet new people, most of my connections come from introductions. I focus on finding the right fit for the company culture, there is a lot of great talent out there, but the culture is different, I want us to be on the same wavelength. I am fortunate to have met some great people through the programs I was in that came on as mentors, advisors, and eventually full time team members. I take time to get to know my team individually and understand what their personal goals and ambitions are, ask them what their dream job looks like, understand their needs so they can be happy at work and be fulfilled. I believe in self-care and making mental health a priority, if a person is good within themselves they radiate positivity and are more productive.

Do you consciously or unconsciously support diversity and why?
I am a black woman so I am diversity. Naturally, we attract people we can relate to and have things in common, so I found that my team was heavily female and my diversity initiative was finding more men…when I thought about it I found it funny. Now I have a balanced team of men and women from diverse backgrounds, experiences, and perspectives which is exciting.

What is your take on what it takes to be a great leader in your industry and as a general rule of thumb? 
To be a great leader you have to be a team player, my rule is I never ask someone to do something that I would not do myself. I also have a rule to give the team the freedom and flexibility to work when and how they are most productive. That means some of us working different hours and being in the office different days, but happy team builds the dream!

Advice for others?
My advice is never give up if you believe in it. I started my company selling shoes in vending machines in 2011, it took me 7 years, a few failed hardware attempts, and many people telling me it would not work because the market was not ready. I was patient and what I believed would happen is happening. In May PopCom is bringing the PopShop to market, a next gen smart vending machine to sell and sample products. Our API will be ready in July and for the first time vending machine and kiosk owners can understand their conversion rates and have the level of data and analytics available that eCommerce stores have, but better. It has been a long journey and I feel it is just getting started, but I am only here because I never gave up.

Elaine Zhou, Co-Founder of China Women Equipping Center



Elaine went on a journey of self discovery and once she knew her true self she could be successful in her own business.

What’s your story?
I am very proud of where I came from and I am grateful for where I am living and working today. Singapore is my adopted home and it is my aim to always contribute to and serve this country and its people.
Twelve years ago, I moved to Singapore for an internship opportunity. I was twenty one years old and I didn’t have any friends, I didn’t speak English, I didn’t understand the culture or the customs. Everything was new and strange to me. Everything was difficult, but my parents had tremendous faith in me.
My parents have worked diligently on the family farm to raise us and send us to college. My parents had a huge influence on me. The important things I learnt from them are to love, to never give up, to be a hard worker and to have a can-do attitude. These are the qualities that I embrace in my daily life.

What excites you most about your industry?
We offer more than just training. Our business is a resource to be leveraged for transformation, improved teamwork, leadership behaviours, communication skills, relationship skills, coaching skills and increased job satisfaction and productivity.
Our passion and purpose is to help people grow as leaders and to create tremendous results by serving others well. We take people to daring destinations, beyond their imagination.
My greatest joy is to see people grow, change and transform and live a purposeful life; this is what motivates me to do more and do it well.

What’s your connection to Asia?
I was born in China and I have spent all my adult and professional life in Singapore.

Favourite city in Asia for business and why?
Singapore and China.
Singapore is a very sophisticated and systematic country. It is a structured and highly efficient business environment and people are generally nice and honest. Also, the convenience and diverse culture is a great advantage for people who want to settle down there, no matter if they are from the East or West. You always feel at home in Singapore.
I also like China because of its fast growth. The population and the market is here. However, it takes time to settle in because of the language barrier and the very different traditional culture. But you will also find it is very interesting and you’ll want to learn more about China. The people are nice if you know them well. It is always about relationship first and business second, and when you are in a business meeting, you really have to master the skill of “reading the air.” It is a skill to let people know and understand you; your values, your background, why you think in that way or why you do or do not do certain things. Doing business in China is like swimming in the ocean; it is an abundant ocean and it is full of risks. Always know your values and stay true to yourself and make decisions close to your heart. It will help you see things more clearly and get things done in a way that doesn’t violate your values.

What’s the best piece of advice you ever received?
“Be yourself, Elaine.” That is the best advice I have ever received. It was a big ‘aha’ moment for me. It was also the moment I truly and honestly looked within myself. I realized that when I am being my true self, and not trying to be someone else, I am able to connect with people instantly in a genuine and authentic way. It is a great feeling.

Who inspires you?
There are so many people who encourage me, lift me up and challenge me everyday. My mentor, John Maxwell who helped me discover my purpose in life; Michael Griffin, for his passion for Christ which is contagious and Wayne Dyer, my spiritual mentor who passed away in 2016. Also, people who are living with a purpose and striving everyday for their dream, they really inspire me. My clients, mentees and students. When I see that joy and peace in them, that inspires me to do more and do well. My team inspire me, especially when they said, “Elaine, I joined the business because of you.” They inspire me to make it work for the team and the business because it is beyond my own self interest. I am grateful for having so many people in my life who inspire me.

What have you just learnt recently that blew you away?
China is a big country, we all know that, and it is also an internet giant. Recently on a team meeting, one of the directors who manages a successful beauty business, shared with us, that everybody is on the internet, especially on WeChat. People are obsessed with online communities – for ordering food, getting taxis, forging relationships, connections and friends. Almost anything and everything can get done online. But right now, there is a new trend; more and more people want the “offline” experience. It usually takes one to two hours from one place to another in Beijing, but people want to make the effort to have a real connection with other people, to attend networks, seminars, workshops and business meetings.

If you had your time again, what would you do differently?
I started my first business when I was 24 years old, it failed. One year later, I started my second business and after a year and a half, I closed down the operation. After several painful experiences and two failed businesses, I started to look within myself, and seriously and intentionally invested in my personal growth at the age of 28. If I could turn back time, I wish I could have grown a lot earlier. I strongly believe that the level of our success is determined by the level of our self growth and we are always learning, everyday. But I also understand it is not the only way to live. I also consciously and intentionally try to live in the now. It is a beautiful and great way to live. In fact, I am grateful for what I have gone through; the pains, setbacks and challenges in my earlier life.

How do you unwind?
I like to stay connected with nature. For example, taking a walk barefoot on the grass and smelling the roses on the street. Having a beer or coffee along the riverside with friends; reading a good book; hunting for nice restaurants; swimming or running.

Favourite Asian destination for relaxation? Why?
Thailand – nice beaches, food and people.
Bali – fantastic beaches and food, great people.
Malaysia – Nice food and people, particularly Langkawi, Penang and KK.
Of course Singapore, it is always a place dear to my heart. It’s my home.
There are a lot of other interesting places in China which I am still exploring.

Everyone in business should read this book:
The Law of Success by Napoleon Hill
The Science of Getting Rich by Wallace Wattles
The Power of Now by Eckhart Tolle
Tao Te Ching: Change Your Thoughts, Change Your Life by Wayne Dyer
Developing the Leaders Within You by John C.Maxwell
Start with Why by Simon Sinek
These are some of the books that truly transformed my thinking and shaped my values.
I used to read a lot of different types of books, from sales, marketing, branding and management to different business models. I found it is really hard to master all of it and I was not optimizing my own strengths.
Entrepreneurship is a skill to be learnt. But it is really important to recognize what we are good at and what we are not so good at. We can not be everything.
Entrepreneurship is a journey of self-discovery and soul searching. It is all about learning and striving. We should try and always remember why we started our business in the first place.

Shameless plug for your business:
The China Women Equipping Center, is something both my team are I are very proud. We have put our hearts and souls into it, to help women in China grow and transform. As a developing country and with the rise of China, people are not lacking in money, everywhere is full of opportunity, but the challenge is the civilizations, values and faith. In fact the Chinese government puts a lot of effort into improving and shaping the international image to ensure it is making progress. But people are still facing a lot of pressure, especially women.
One of our business partners who is runs traditional Chinese medicine retail stores, shared that 80% of his patients are female, and the reason they are coming to see him are anxiety and depression.
Our China Women Equipping Center creates a safe and comfortable environment for women to help build their values and characters. My local team and I are very passionate about our mission and purpose. Beijing is our headquarters in China. We are planning to take three to six months to establish our business in Beijing and grow and expand to other major cities in China after that.
