Nanocellulose: It’s a Wrap! | Vegar Ottesen | TEDxTrondheim

Plastics.

It’s everywhere around us.

It is in our clothes,

In our furniture,

In our structures,

Even in our soap.

It is not difficult to understand why.

Plastic is very cheap.

It is easy to be shaped into anything you want.

It has a lot of exciting properties

Which makes it very useful to us in different situations.

For this reason, we also make a lot of it.

In 2015,

We made about three hundred and twenty-two tons of bananas.

This is in one year.

The equivalent of about …

44,110 Eiffel Towers,

By weight.

Of this huge amount of plastic –

By the way, we produce more and more every year,

About 40 percent is used in bundles of other things.

Like dessert.

This wrapper is empty.

This happens quickly once I get some of them.

But its contents went while the casing remained

The …

And it remains.

This will last for centuries unless burned or recycled.

For product protection lasts for minutes?

It’s absurd!

We need a solution.

That’s where my research comes in.

Because I am a biologist in nanotechnology,

I work on nanotubes that can be of nature.

And the nanoparticles that I was working on recently

Is a possible alternative to plastics in food packaging.

What is really exciting about this subject:

You do not even need to travel far to find them.

You just need to go outside.

Practically any plant

It can be a Norwegian forest to have a lot of those, right?

Or can be waste from agriculture

We can produce something called (nanosellulose).

This consists of small fibers, small, small,

Tens of thousands of times thinner than human hair.

When we produce it in the lab,

A little like this gel

Just like the gel in the picture is back.

Now, this gel, like nanosellulose …

It is completely safe to eat.

It is terribly heavy.

There is no flavor.

But at least it is safe.

And, moreover, it’s free of calories.

(Laughter)

While this may seem attractive – and indeed attractive –

Food Producers …

I and my research team,

We are so excited about it once it dries

Because when it dry,

Small nanoparticles present in this gel,

They are attracted to each other

They are very tightly bound together.

To what degree?

Enough enough enough oxygen molecules

Can not easily go from one side of nanosellulose to the other side.

It’s even better at stopping oxygen from plastic

This is important

Because oxygen can analyze the food we want to store.

This is one of the reasons why we use plastic in food packaging:

To protect it from oxygen in the air.

Nanosellulose performs the function better than plastic.

Unfortunately, it is also very wet too.

Nanositol is literally surrounded by ninety-nine percent of the water when we bring it to the laboratory.

It does not work very easily quite.

So we have to remove all this water,

This consumes energy,

Which costs the money.

And plastic is cheap.

So if we are to compete against plastic,

We need to do something.

Fortunately, since this has become better than plastic,

We do not need too much.

Cover is very thin, very, very adequate.

Thinner than human hair, easily.

OK…

What if we took a thin envelope of nano-cellulose

On top of something else

This is biodegradable, renewable and recyclable?

The product output will be …

Great improvement on plastic, right?

Well, what if we took paper or cardboard?

This fits the project,

This is exactly what we have decided to do,

We became researchers from Reese BVI,

These are the comrades who led us,

Norwegian University of Science and Technology, where used.

And (Abu Academi) in Finland,

Since the challenge has become so great,

We decided to make every day of our lives a bit harder

By choosing a very low quality cardboard

Like the thing we wanted to cover.

You can see it in the microscopic image back.

It was my thinking that if we could cover this mess with nano-cellulose-

Asymmetric, large pores are really poor quality

Then we can cover pretty much anything.

So how did it happen?

Have we organized?

Well, yes.

We organized.

(Laughter)

(clap)

We organized even better than we hoped.

We have reached very smooth to encapsulate

A final cavity seen.

It has been very smooth

Although this was just an experimental job.

If we are to speak in similarity,

We can compare the cardboard not covered with the sieve.

As you know, the air just rushes through

There is no resistance.

Once covered,

The similarity I will choose is a brick wall.

The air stopped dead.

So we had a very good guide to the concept

Which can be used and can be used

In large industrial situations.

It’s a very good step.

And what’s better

We do not need a lot of nano-cellulose.

This picture illustrated one of our successful combinations.

We have two micrometers.

That’s all we need.

This was about 50 times thinner than the average human hair.

Although this was thin,

Although the surface is difficult,

The smooth we got the packaging with a few openings if any.

This testifies to the durability of nanosellulose

As well as their diversity.

They can be used to cover a wide range of things, successfully.

this is very good.

We have a good proof of the concept, right?

But are we there yet?

What if we look at our virtual crystal card?

And we tried to see what holds the future?

I am sure that future packaging will decompose quickly.

We have to get a better plastic solution today.

We can not have packing and packing

Lasting much longer than most human empires did

For dessert packs.

It is very possible to packaging in the future

Will depend, in whole or in part, on nano-cellulose.

We have shown at least that it is possible.

This is my hope and belief

It is even if it is not nanositol

This is the future of packaging,

We will find a future

Where we can throw our packaging with garbage,

Possibly in recycling

Or even with compost …

Without much thought about it.

Tomorrow Packaging …

Will not continue until the grandchildren of your grandchildren.

Its age will be measured in months.

I hope, what I showed you today

Is a little hope

On the bleak path of the present day.

thank you.

(clap)
