JUDY WOODRUFF: Now to our series on the plastics problem around the world.
As we said last night, one of the biggest problems is actually how to recycle the material
in the U.S.
In this country, the rate of recycling plastics is just 9 percent.
That compares to 30 percent in Europe.
Amna is back with a report that took her to three states, exploring innovative ideas aimed
at reducing plastic waste.
It's part of our Breakthroughs reporting on invention and innovation for our series the
Leading Edge of science.
AMNA NAWAZ: For over 40 years, this is one of the ways we have tried to tackle our growing
plastic problem, sorting, weeding out, and sorting some more, like in this Seattle facility.
Every day, an estimated 750 tons of material go through this process.
And every step along the way, just like this one, is designed to remove one more material.
For an ultra-durable material like plastic, the goal of this system was to get us to use
less by reusing what we'd already made.
Today, new innovative ways of recirculating our plastic are being road-tested, literally
in this case.
This is the very first plastic road in the U.S., on the University of California-San
Diego's campus.
Toby McCartney is behind MacRebur a British start-up that mixes recycled plastic pellets
into asphalt to make longer-lasting and cheaper roads.
TOBY MCCARTNEY, Managing Director, MacRebur: The downside to waste plastics is, it lasts
for so long.
A bottle will last for maybe 500 years.
What we're using is the ability of those plastics, because they last so long, but in our roads.
We want our roads to last so long before they need any maintenance.
AMNA NAWAZ: But are reusing and recycling really making a difference?
ROLAND GEYER, University of California, Santa Barbara: I would say that the way we recycle
plastic at the moment is not part of the solution.
I would even go as far as saying it's part of the problem.
AMNA NAWAZ: Roland Geyer is an industrial ecologist at the University of California,
Santa Barbara.
He says that in the 70 years plastic has been around, we have created nine billion tons
of it, most of which still exists.
ROLAND GEYER: The only plastic that does not need to be disposed of is plastic that was
never made.
So even recycled material, you can't cycle it forever.
BECCA FONG, Seattle Public Utilities: Not all plastics are created equal.
AMNA NAWAZ: Becca Fong of Seattle Public Utilities walked us through the city's impressive and
growing recycling effort.
Still, she says, the process isn't perfect.
BECCA FONG: It's geared to capture certain types of plastics of certain sizes.
And if it doesn't fit into those categories, it's not really recoverable.
AMNA NAWAZ: So, speaking of certain sizes, something like this, a tiny little plastic
straw, where does something like that straw fit?
BECCA FONG: The fact that it made it here is pretty impressive.
But the vast majority of small items are going to fall through the machinery and not be able
to be recovered to be recycled.
AMNA NAWAZ: So, Seattle started small and in July became the first major city in the
U.S. to ban all plastic straws.
It is that piece of material that is so small and so nuanced and actually kind of an extra
for a lot of people, that it actually makes people stop and think, do I really need to
have this straw?
And that's probably the bigger impact.
MAMI HARA, Director, Seattle Public Utilities: A straw that I use today in Seattle can end
up in the Pacific Ocean and last there for thousands of years, or it can return back
to your plate in 10 years as microplastics embedded in some fish.
AMNA NAWAZ: Mami Hara heads up Seattle Public Utilities.
Before her team could implement and enforce the straw ban, which also includes plastic
utensils, they had to get local businesses on board.
MAMI HARA: For a lot of businesses, it hasn't been a hard sell.
For those who are concerned about the price point, we try to work with them to find viable
alternatives that don't impact their purse too much.
BOB DONEGAN, President, Ivar's: We will buy about a million straws this year, and the
cost of straws has tripled.
AMNA NAWAZ: Bob Donegan is the president of Ivar's, an 80-year-old Seattle seafood institution.
BOB DONEGAN: We don't routinely put a straw in a drink.
We ask everybody, would you like a straw?
And they can always have one.
And these are the new compostable straws.
They are made from plants.
AMNA NAWAZ: But the compostable straws don't work for him in other ways.
BOB DONEGAN: So I challenge you to suck a milkshake through that straw and see if you
can make it.
AMNA NAWAZ: That's not easy.
BOB DONEGAN: It's pretty hard.
AMNA NAWAZ: So he spent more money and ordered bigger straws.
Since the ban, costs have gone up.
But Donegan says he budgeted around them by buying goods early and in bulk.
So there's no use, he says, in complaining.
BOB DONEGAN: Put on your big boy pants and get used to it.
Everything the government does isn't fair.
But our customers expect it of us, and we want to do what our customers want.
WES BENSON, Taco Time Northwest: Not only are we saying that the environment is important
to us.
This is a way for us to put our money where our mouth is.
AMNA NAWAZ: Wes Benson at Taco Time, another area food chain, says they took Seattle's
straw and utensil ban one step further.
Today, every single item they give customers, from utensils and cups to plates and bowls,
is fully compostable, meaning they're made of natural materials and can be turned into
compost after being tossed.
WES BENSON: One of the nice things about being 100 percent compostable is, you can make it
a part of your story.
And we're a local company.
The environment is important to us.
And we're willing to pay five times as much for our packaging.
AMNA NAWAZ: Seattle's efforts to cut back on plastic extends beyond restaurants.
Behind the scenes at Safeco Field, we get a look at the stacks of compostable items
they now require food vendors to use.
Last year, the park managed to recycle or compost 96 percent of all waste.
Trevor Gooby runs operations at the ballpark.
TREVOR GOOBY, Safeco Field: It definitely is more work to sort through the trash that
we have after the game and to do these type of things.
But, again, we feel it's really important for our business.
And it's important because our fans are asking us to do it.
AMNA NAWAZ: All those compostable items end up in piles like these, at facilities like
this, run by Jason Lenz and his family outside of Seattle.
For what you guys do, how much of a problem do plastics present?
JASON LENZ, Lenz Enterprises: I would say it's a you know it's not insurmountable.
At the same time, it's -- it's definitely a problem.
AMNA NAWAZ: Even hear, bits of plastic need to be sorted out.
Lenz has been in this business since 2008, after expanding his sand and gravel company.
So, without the city asking this of you or showing that there was a demand for this,
you guys likely wouldn't be doing this?
JASON LENZ: That's correct.
Seattle is a big pusher of organics diversion for compost, yes, so that's why we're in this
business.
AMNA NAWAZ: Lenz's company now turns out hundreds of thousands of tons of compost a year and
sells it to everyone from soil companies, to local governments, to home gardeners.
What is in here?
MORGAN VAGUE, Reed College Graduate: So these are bags of dirt that I collected from various
sites around the Houston area.
AMNA NAWAZ: Reed College student Morgan Vague had a hunch: If plastic really is everywhere,
maybe, in heavily polluted areas, bacteria have evolved to eat it.
And maybe those bacteria could take a bite out of our plastic problem.
So she collected samples from some of the dirtiest places around her hometown of Houston,
Texas, like sites of past oil spills and sites deemed contaminated by the EPA, and brought
them back to the lab.
So, you identify the bacteria you want to take a closer look at.
And then you put them in these test tubes.
MORGAN VAGUE: Yes.
AMNA NAWAZ: And the only food you give them, basically, is these plastics.
MORGAN VAGUE: Yes, exactly.
And we're fortunate to find some that did a pretty good job.
AMNA NAWAZ: But Vague found that the bacteria works much too slowly to be useful just yet.
MORGAN VAGUE: What a lot of our research is focused on is sort of like, how can we speed
up this process a bit?
How can we kind of scale this up and get it to an applicable kind of stage?
Because, you know, right now, it's just bugs in a tube.
AMNA NAWAZ: Vague says yes, it's just one study in very early stages, but she's excited
for where it could lead.
MORGAN VAGUE: All little girls want to change the world when they grow up, right?
I think we need more of these kind of grassroots efforts and kind of thinking outside the box,
or outside the plastic bottle, and kind of saying what sort of solutions we can find.
AMNA NAWAZ: Without meaningful solutions, experts warn, our trajectory means more and
more plastic on our land and in our water.
According to one study, if current production trends continue, by the year 2050, there will
be more plastic than fish in our oceans.
Geyer says one way to fix it, get rid of all single-use packaging, things like bag, straws
and bottles, that make up 40 percent of our plastic.
ROLAND GEYER: That would make a huge difference.
That will be -- and I think it's really doable.
Lots of people are at a point where they don't like what they see, that there's real willingness
to change behavior, to do things differently.
And I think there are many, many ways we can do it, then still allow us to have the good
life.
AMNA NAWAZ: To do that, experts say it will take governments, companies and individuals
working together, each taking small steps to bring about big change.
For the "PBS NewsHour" in Santa Barbara, California, I'm Amna Nawaz.
JUDY WOODRUFF: And, tomorrow, we will take a look at why China is no longer accepting
much of our recycling, including plastics, and the impact that's having.
