Entrepreneurship

This Japanese Startup Is Innovating with Crab Shells

Published

on

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.

Andrew Schorr, Founder of Grata

Published

on

Taking a different route throughout his life, Andrew Schorr ended up in China and started several businesses.

What’s your story?
I moved to China after I graduated from college in 2004. English teaching was the easiest way to get there, so I looked on a map and picked a small town in Hubei, because it looked to be more or less in the middle of China. I was the only foreigner there.

Back then, everything was about the upcoming Olympics in Beijing, so I moved to the capital after my year of teaching. Pretty soon after arriving, I met the co-founder for all three of my companies. We decided to start a company together the first day we met. He has now moved back to the US and builds flight software at SpaceX.

Our first company, an online city guide, was re-purposed into our second company, GuestOps, a web concierge platform. We sold GuestOps to most of the major international hotel brands in China and still operate it. The genesis of our latest company, Grata came from looking at the intersection of hotels and WeChat in 2012, when WeChat was just starting to blow up. Grata expanded from hotels into a live-agent customer service console.

What excites you most about your industry?
Our thesis with Grata has always been that what is happening with WeChat in China is the future of messaging platforms globally, and as an international team building on WeChat, we would be well-placed to capitalize on that trend. It’s taken longer than we expected for the industry (and us, for that matter) to get there, but finally, we’re starting to see messaging as a platform to get better traction in other markets.

What’s your connection to Asia?
I’ve always been a bit of a contrarian. I grew up in Texas, where all my friends studied Spanish in school. I studied German for no reason in particular. I took a similar path in college: Chinese and Japanese seemed like languages that not a lot of people who look like me studied. I was one of only two students in my third-year Chinese class.

Favourite city in Asia for business and why?
Shanghai. I should live there, but Beijing has been home for so long. I take the night train down to Shanghai every two-three weeks to meet with clients. Domestic flights are way too unreliable here.

What’s the best piece of advice you ever received?
Don’t plan too far ahead; otherwise, you plan yourself out of good opportunities.

Who inspires you?
Has anyone said “Elon Musk” yet? Barack Obama would be another.

What have you just learnt recently that blew you away?
The gravitational waves recently detected from neutron stars colliding, were so subtle as to only affect the distance from earth to our closest star, Alpha Centauri (4.24 light years away) by the width of a human hair. Perhaps in another life or in the future, I’ll be an astronomer, but a telescope doesn’t do me much good in Beijing.

If you had your time again, what would you do differently?
When I give advice to students looking to get into entrepreneurship, I advise them to work for a post-Series A startup first and learn from a company that’s already doing things well. I learnt everything on my own, which is slower and you pay for your own education. If you work for a startup that’s small in the beginning, you risk learning bad habits.

How do you unwind?
I Hash! The Hash is a drinking club with a running problem. The Hash attracts good people from all walks of life and doesn’t take itself too seriously. It’s a great way to meet fun-loving people all over the world. It’s also how I met my co-founder, our first lawyer, and my girlfriend.

Favourite Asian destination for relaxation? Why?
Pulau Perhentian, Malaysia. A fantastic beach and where I first learned to scuba dive.

Everyone in business should read this book:
For business in China, Tim Clissold’s, Mr. China.

Shameless plug for your business:
Grata does WeChat contact centers for many top-tier brands in luxury retail, travel, financial services and hospitality. We started developing on WeChat before they even had an open platform. Grata provides the most value for large enterprises with complex routing and content demands for their contact centers.

Benjamin Kwan, Co-Founder of TravelClef

Published

on

Making music to create a life for his family, Benjamin Kwan, started an online tuition portal and his music business grew from there.

What’s your story?
I am Benjamin and I’m the Co-Founder of TravelClef Group Pte Ltd, a travelling music school that conducts music classes in companies as well as team building with music programmes. We also run an online educational platform which matches private students to freelance music teachers. We also manufacture our own instruments. I started this company in 2011 when I was still a freshman at NUS, majoring in Mechanical Engineering.

I was born to a lower income family, my father drove a taxi and was the sole breadwinner to a family of 7. I have always dreamed of becoming rich so that I could lessen the burden placed on my father and give my family a good life.

After working really hard in my first semester at NUS, my results didn’t reflect the hard work and effort I put in. At the same time, I was left with just $42 in my bank account and it suddenly dawned on me that if I were to graduate with mediocre results, I would probably end up with a mediocre salary as well. I knew I had to do something to gain control of my future.

During that summer break, I read a book “Internet Riches” by Scott Fox and I knew that the only way I could ever start my own business with my last $42 would be to start an online business. That was how our online tuition portal started and after taking 4 days to learn Photoshop and website building on my own, I started the business.

What excites you most about your industry?
Music itself is a constant form of excitement to me as I have always been an avid lover of music. As one of the world’s first travelling music schools, we are always very eager and excited to find innovative ways to a very traditional business model of a music teaching.

What’s your connection to Asia?
I was born and raised in Singapore and I love the fact that despite our diversity in culture, there’s always a common language that we share, music.

Favourite city in Asia for business and why?
Hands down, SINGAPORE! Although we are currently in talks to expand to other regions within Asia, Singapore is the best place for business. I have had friends asking me if they should consider venturing into entrepreneurship in Singapore, my answer is always a big fat YES! There’s a low barrier of entry, and most importantly, the government is very supportive of entrepreneurship.

What’s the best piece of advice you ever received?
I have been blessed by many people and mentors who constantly give me great advice but right now, I would say the best piece of advice that I received would be from Dr Patrick Liew who said, “Work on the business, not in it.” This advice is constantly ringing in my head as I work towards scaling the business.

Who inspires you?
My dad. My dad has always been my inspiration in life, for the amount of sacrifices that he has made for the family and the love he has for us. He was the umbrella for all the storms that my family faced and we were always safe in his shelter. Although my dad passed away after a brief fight with colorectal cancer, the lessons that he imparted to me were very valuable as I build my own family and business.

What have you just learnt recently that blew you away?
You can not buy time, but you can spend money to save time! With this realisation, I was willing to allow myself to spend some money, in order to save more time. Like taking Grab/Uber to shuttle around instead of spending time travelling on public transport. While I spend more money on travelling, I save a lot more time! This doesn’t mean that I spend lavishly and extravagantly, I am still generally prudent with my money.

If you had your time again, what would you do differently?
I would have taken more time to spend with my family and especially my father. While it is important to focus our time to build our businesses, we should always try our best to allocate family time. Because as an entrepreneur, there is no such thing as “after I finish my work,” because our work is never finished. If our work finishes, the business is also finished. But our time with our family is always limited and no matter how much money and how many successes we achieve, we can never use it to trade back the time we have with our family.

How do you unwind?
I am a very simple man. I enjoy TV time with my wife and a simple dinner with my family and friends.

Favourite Asian destination for relaxation? Why?
Batam, it’s close to Singapore and there’s really nothing much to do except for massages and a relaxing resort life. If I travel to other countries for shopping or sightseeing, I am constantly thinking of business and how I can possibly expand to the country I am visiting. But while relaxing at the beach or at a massage, I tend to allow myself to drift into emptiness and just clear my mind of any thoughts.

Everyone in business should read this book:
Work The System, by Sam Carpenter. This book teaches entrepreneurs the importance of creating systems and how to leverage on systems to improve productivity and create more time.

Shameless plug for your business:
If you are looking for a team building programme that your colleagues will enjoy and your bosses will be happy with, you have to consider our programmes at TravelClef! While our programmes are guaranteed fun and engaging, it is also equipped with many team building deliverables and organizational skills.
