- Plastic is a problem. But what is the solution to the most ubiquitious substance in our lives? Look no further than, well, any plant you can see! Nanocellulose is plant material that when it meets paper a true replacement that will be healthy for our future happens. Learn from nano-scientist Vegar Ottesen what this magic substance is all about. Vegar Ottesen is a nanotechnologist, proud father, scientist, burgeoning podcaster and science disseminator. Currently employed at NTNU and working on the NORCEL project led by RISE PFI; he is researching for a novel and green solution to eliminate the need of plastics for food packaging.
Having lived outside of Norway in his youth and often travelling with his wife, he has a keen appreciation for other cultures. While working on projects that have long-term sustainability and global benefits, he recognised the importance of science and technology for humanity's survival. Vegar believes that it is essential to speak about science as frequently as possible in a way that allows it to be understood and is accessible by all. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

I notice I misspoke, I meant to say we made 322 MILLION metric tonnes in 2015. (Source: Plastics Europe)
Thanks for saving me on the English presentation Cheers from Sweden
Thanks for the talk. How is the research progressing?
Glad you enjoyed it. The research is progressing nicely, my own portion of the project is coming to a close next month (May), shortly after I defend my PhD thesis at the end of April 2018. The research itself progresses both at RISE-PFI and NTNU in Trondheim, Norway, as well as Åbo Akademi in Turku, Finland. There are many other research groups across the world working on the same problem, and progress continual.
Vegar Ottesen Hi! I am from Argentina. Me and my team are competing in a Biotec undergraduate competition. We are trying to produce a novel meat packaging bounding lactoferrine to the bacterial cellulose.
The thing is that the texture is not even close to normal packaging (it's like a never dried and if we dry it is like a strong paper).
Maybe you could give us an advice.
Thanks for your attetion!
Vegar Ottesen 👌👌
Vegar - Great Ted Talk. I am doing a research project for an undergrad class on nanocellulose. It has been nearly 4 years since this presentation. What new are some new things that you have discovered in that time? Keep up the good work!
There are many factors. One of them is heat/temperature. Rise in temperature would lead to significant thermal decomposition of cellulose at high temperature. Another one is biodegradation. We need to coat the packaging material with an antibacterial coating. This layer/coating should only persist for few months to avoid contamination and degradation of biomaterial from harmful (pathogenic)bacteria.
*More packaging companies need to know about this !*
Wonderful material. This NanoCellulose + Paper could replace most of the plastic packaging that does not need transparency.
I wish I could like this video more than once. Great job.
This was a great TED talk! =)
I really think nanocellulose is promising material too. However, I think indeed the safety aspects need to be resolved and that the degradation in nature of paper +nanocellulose should be shown too. Some types of nanocellulose (depends on fabrication method) can be quite intractable. So, if it is degradable in ?3 months?, can you show how? Which types of bugs can degrade nanocellulose fibrils, under which conditions, for how long?
Thanks! Hope this research is still on!
Japan is probably the leading reasearchers on the field of nano-cellulose.
They made a fully functioning supercar primarily composed of parts made from nano-cellulose.
great job!! :)
Very good and inspiring talk. Excellent preparation and delivery - textbook TED. (The missing million is trivial as the film subtitle adds it in; but I think it’s funny that nobody in the filmed audience was flabbergasted or scratching heads.) Does Dr. Ottesen continue NC or maybe also MCC research? Are there opportunities for collaboration with paper & packaging companies in Europe and America?
Thank you very much, Dr. Isele. I am indeed continuing to work on cellulose nanomaterials as a post-doctoral researcher for the next few years. Should you be interested in discussing opportunities for collaboration we are certainly open to talk about that. Feel free to drop me a few lines, my contact information is readily available on-line.
@@VegarOttesen hi sir, the talk was really superb and i would like to let u know that iam doing biotech engineering and on the way to final year project based on cellulose nanocrystals. Is there any way i could get a help from you?
I LOVE IT
2:47 HOHOHOH LOL that's one way to show it's safe to eat XD
How much will it cost to coat a small cardboard box this should be made into production of a packaging company
Who disliked this great video
owners of plastic factories.

Всё классно, но шаблонность эмоций - это 3,14**ец
Why is this guy not a professor by now? All the bright minds are leaving science.
First!

What happens with nanocellulose after people eat it? We don't know all the biological processes of nanocellulose in human body. Nanocellulose may behave differently compared to cellulose in human body. What are the negative effects of nanocellulose after it was ingested?
dude its just wood fibers from trees. Nothing dangerous about it
How do you know it is safe? Answer: you don't! Don't say something is totally safe when you don't have any clue!
It's made from wood pulp. Do you freak out when you handle a cardboard box?
he ate it
the guy literally ate it, its wood fiber from trees?! How is it not safe? You think he would eat it if its not safe? Please your head for once and stop following the bandwagon like everyone else
