Our plastic planet
We have sipped, packaged and played our way into a global plastics crisis, Andrew writes.
- Why it matters: Activist consumer groups are pushing for less use and less production, while industry aims for increased recycling.
- The big picture:Plastics demand is projected to only increase — and the footprint of plastic pollution will grow with it.
- Just 9% of plastics were recycled in the U.S. in 2015. (Globally it was estimated to be about 20%.)
Driving the news: This week, Canada announced it plans to ban single-use plastics — likely bags, straws, plates, etc. — by 2021.
- Canada’s move is part of a broader trend at various levels of government to restrict or ban certain types of plastics.
- And there’s a growing “zero waste” movement on social media.
- Microplastics — bits of plastic less than 5 millimeters long — have been found on the farthest cornersof the planet.
- What’s not yet knownis the toll it’s taking on our health.
What’s next: Since most plastics come from fossil fuels, our plastics dependency is also exacerbating climate change.
-By the numbers: All the plastic we’ve produced
Plastics are increasingly hardwired into the global economy, from shipping to building to computing.
- Key stat: In 65 years, we’ve gone from producing very little plastic to more than 400 million metric tons in 2015.
Go deeper: The global plastic problem is even bigger than you think
-Big Oil doubles down on recycling
Companies across the plastic supply chain are unifying around lofty plans to fix the world’s abysmal recycling record as a way to simultaneously protect their profits and respond to growing pressure, Amy writes.
- Driving the news: More than two dozen companies, including ExxonMobil and Procter & Gamble, formed a coalitionearlier this year seeking to pour more than $1 billion into increasing recycling.
Where it stands: Petrochemicals accounted for half of the growth in global oil demand last year, according to a report BP released this week.
- 70% of global oildemand growth by 2040 is anticipated to be used mostly for plastics, according to an annual energy outlook BP issued earlier this year.
- Why it matters: The company found a worldwide ban on single-use plastics would cut the growth of oil demand roughly in half over the next two decades.
- ExxonMobiland Saudi Arabia-based SABIC got final approvalthis week to build in Texas what will be one of the world’s largest facilities processing ethane, the single largest North American feedstock (raw material) for petrochemicals used in plastics.
The other side: Environmentalists argue industry’s focus on recycling reinforces the world’s plastic dependency.
-Solving the plastic problem
Plastics are intertwined with our lives — driving researchers to create plant-based versions and more efficient ways to recycle, Alison writes.
The big picture: From a science perspective, the biggest challenge is consumers and companies want materials that won’t degrade quickly while being used, but will degrade quickly once disposed, says Andrew Dove of the University of Birmingham in the U.K.
- “The world wants it both ways,” he says.
How it works: Plastics are recycled or burned as a source of energy. But by one estimate, 79% of plastic waste has ended up in landfills or the environment.
- Plastics can be mixedwith pigments, other materials and other plastics, which complicate recycling and limit how the chemical components of plastic can be reused.
The push for “green plastics” made from sustainable materials has given us cups made from corn-based plastic (polylactic acid) and compostable chip bags that can degrade.
Replacing petroleum-based plastics is still important in the long term, says Dove. But as it accumulates in landfills, researchers are increasingly focusing on new ways to make and recycle today’s materials.
- Lawrence BerkeleyNational Laboratory researchers recently reported an alternative process for creating a plastic commonly found in epoxies and polyurethane.
- They were then able to break it down to its chemical building blocks, even when the plastics were colored or with other materials, and turn them back into plastic.
Scientists are also experimenting with degrading plastics using:
- Chemicalrecycling: Different acids and bases can be used to break down plastics. Researchers hope to develop chemicals that can selectively degrade a single type of plastic in a stream of mixed plastic waste.
- Enzymes: They have the advantage of being specific to a type of plastic but the disadvantage of working slowly compared to chemical recycling.
-Oh, the places plastic will go
Some places plastics have been found, Jessie reports:
- Point Nemo. In the most remote spot in the ocean, scientists found particles of microplastics.
- The Cocos Keeling Islands. A marine biologist found 373,000 toothbrushes and 975,000 shoeson the beaches of a remote string of islands in the Indian Ocean.
- A dead whale’s stomach. Rescuers found more than17 pounds of plastic, including 80 shopping bags.
- The French Pyrenees.Scientists found microplastics at an altitude of 4,500 feet on an isolated, pristine site.
- Several water samples detected microplastics in remote parts of the Antarctic.
- Bottled water. A study of 259 bottlesfrom nine countries found 93% showed microplastic contamination.
- Human excrement. Researchers tested stool samplesfrom across Europe and found plastic particles in every single one.
–Parents against plastic
Some parents, as part of a growing zero-waste movement, are refusing to buy plastic toys, Jessie writes.
- Many parents in a popular zero-waste Facebook group (100,000+ members) opt for wood, fabric or paper toys.
- Some won’t accept gifts of plastic toys. “If I can return the gift, I do,” New York City parent Megan Kip-Holden tells Axios.
What to watch: Toymakers are also seeking sustainable materials.
- Tim Brooks,vice president of environmental sustainability at Lego, tells “Axios on HBO” the company’s scientists have experimented with more than 200 types of material, including corn, wheat and sugarcane.
- But they haven’t found a stand-in for their bricks — only 2%of Lego toys are made of plant-based plastic.
- Other top toy companies are focusing on packaging: Hasbro announced it would start using plant-based plasticsand Mattel said it would start including How2Recycle labels, both this year.
– 1 wondrous thing: The art of ocean trash
Axios commissioned artist Steve McPherson to create a custom piece — featured in the first item of this newsletter — using plastics washed onto the coastline of England.
- McPherson transformsthese discarded, forgotten plastic objects into vibrant, beautiful pieces — forcing the viewer to confront where these objects actually originated, Jessie writes.
Since he started picking up ocean plastic as a child, McPherson has amassed a shocking collection: denture fragments, false finger nails, Lego heads, doll limbs, Scrabble pieces, computer keys, pencil sharpeners and ice cream spoons.
- “The natural colors of the beach were confettied with these synthetic colors,” McPherson tells Axios.
- McPherson says some people who have viewed his art tell him years later that they’re buying less plastic.
