Your Empty Wine Bottle Could Help Rebuild Coastlines | Franziska Trautmann | TED

As a kid growing up on a Louisiana bayou,

the boogeyman was the existential threat

of my state being washed away with the Mississippi River.

Louisiana loses a football field's worth of land every 100 minutes

due to coastal erosion.

It's an unimaginably large amount to a kid.

But in my lifetime so far,

we've lost over 600 square miles.

That's more area than New York City,

San Francisco, DC and Atlanta combined.

It's due to sea level rise,

warming waters, increasingly severe storms

and exploration of the oil and gas industry.

Fast forward to 2020,

in my last full semester as an engineering student

and over a Two-Buck Chuck,

my boyfriend and I lamented over the lack

of glass recycling in Louisiana.

My state was landfilling about 295 million pounds of glass annually.

The bottle we just finished would likely end up in a landfill.

It felt like a total waste,

and we wanted to figure out how we could get all of this glass recycled.

The next day,

it took a quick Google search to remember that glass comes from sand,

and that sand is an increasingly finite resource.

We also learned about everything sand is needed for,

including toothpaste, by the way.

And the last puzzle piece we found was this small, human-sized machine

that could crush one bottle at a time into sand,

and we jumped into action,

setting up a GoFundMe campaign

and a pilot project in the backyard of a fraternity house.

(Laughter)

Now you might be thinking to yourself,

how in the world would two college kids

ever be able to make a dent in these problems?

And that would be valid.

Plenty of people told us the exact same thing.

But we didn’t listen, because we knew

that no matter how small of an impact we made,

it would be worth it.

It felt like we could alleviate two problems with one solution:

convert the otherwise landfilled glass back into sand

and use it in restoration projects across the state.

Easy, right?

(Laughs)

But we didn't listen to the haters,

which is actually why we named our company Glass Half Full.

(Laughter)

But that glass-half-empty mindset

might actually be one of the biggest threats we face today.

Because climate apathy might be the new climate denial.

Meaning that the biggest threat to our environment

may no longer be people who deny our part in the changing climate

but people who deny that we can actually make a difference.

Now climate change is happening right before our eyes.

It's terrifying.

I've witnessed firsthand the severity of rapidly intensifying hurricanes

like Ida.

But dread, doom and gloom tend to get us nowhere.

Whereas hope, combined with action,

can be one of the most powerful tools to enact change.

(Applause)

Since that late night wine-fueled idea over four years ago,

we've been able to divert more than eight million pounds of glass

from our landfills.

Thank you.

(Cheers and applause)

We quickly grew out of that small, tiny machine

and upgraded a lot along the way.

We continue to work with over 50 scientists and engineers

across the Gulf South.

And they helped me learn if this is good-smelling mud or not.

But also understanding the interactions of our sand with the plants, animals

and even fungi of our region.

We've also answered difficult scientific questions

as well as questions like,

can you actually walk on sand made from glass?

And I exposed my toes to the internet to answer that.

In a few short months, we'll be opening up our new facility,

enabling us to recycle the 295 million pounds of glass

entering our landfills annually.

(Cheers and applause)

And with a combination of biodegradable sandbags and native marsh grasses,

we've already restored thousands of square meters along our coast,

converting open water back into thriving wetlands.

(Cheers and applause)

But the key to our success so far

isn’t that we had all of the answers in the beginning

or tons of money to try this thing out.

The key was that we simply started,

and we kept going.

Somewhere, the belief that we, as individuals, could enact change

trumped our doubts.

And for us, finding a way to help with a problem

much, much bigger than us

meant taking that first step.

And in our case, it was a step in the sand,

in an eroding but once magnificent swamp.

Thank y’all.

(Cheers and applause)
