Danish city put out vending machines for people to return their coffee cups and get paid
Only one year later, and the results speak for themselves.

Recycling in action: depositing a reusable cup.
Over 1 billion people worldwide drink coffee every day. That's about 12.6% of the world's population. And of course, there are a bajillion different ways people conjure up their cup of joe, but many opt for swinging by their local café. Problem is, those single-use cups, as we know, create a ton of waste.
Many heavy hitter coffee companies like Starbucks and McDonald’s have made attempts to tackle this issue by incentivizing customers to use reusable cups in exchange for a discount, but one city has a different approach…and it seems to be making a big impact.
One year ago, Aarhus, Denmark’s second-largest city, launched a three-year, first-of-its-kind trial project, where customers can return their reusable coffee cups to automated deposit machines placed throughout town and in return they'll receive a €70-cent rebate back to their debit card.
Once those to-go cups are returned, they’re transported to the TOMRA cleaning/recycling facility, and, barring any damage, will be sent back to participating cafés. According to Euro News, 45 different businesses signed up for the innovative program.
"All of us, we want to have some kind of impact on the amount of trash that's lying around and especially us coffee shops,” said Joe Hougaard, a manager for one of the participating shops.
This scheme is similar to methods introduced by other European countries like Romania, Denmark, and Belgium, which involve deposit systems for returning plastic or glass bottles and cans in exchange for a small refund. However, those machines are only located within supermarkets. The Aarhus system, however, is open air, meaning the machines are located on main shopping streets with a lot of through traffic.
As reported by Daniela De Lorenzo, the project wasn’t an overnight success. Over the initial few weeks after the launch, the return rate was only around 25 per cent, and unfortunately a return rate of 82 per cent would be needed in order for the reusable cups to actually be a better alternative.
However, things turned around in September 2024, when the city held a week-long festival and the reusable cups were exclusively offered. “Many more citizens were exposed to them and around 100,000 cups were returned, an amount which would have filled 1,200 trash bins,” she wrote.
This became a catalyst for change, one that Simon Smedegaard Rossau, project manager for circular packaging at Aarhus Municipality, signaled a noticeable “shift in behavior.”
“We see people going with bags full of cups, which means they recycle in bulk, like for cans and bottles. Now we can see the return rate is 88 per cent, which means a cup is reused 44 times.”
We are only in year one of a three year trial period, but if things continue like this, there are plans to extend the program to plates, pizza boxes and more throughout the city. All of which could be promising for other cities looking for more sustainable systems.
As Tove Andersen, TOMRA CEO, said in a press release, "Aarhus shows the way to one more sustainable future, and we hope that many more cities will be inspired to do the same.”

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
