Biodegradable Mardi Gras beads help make Carnival season more sustainable

NEW ORLEANS (AP) — It is Carnival season in New Orleans. That means gazillions of green, gold and purple Mardi Gras beads.

Once made of glass and cherished by parade spectators who were lucky enough to catch them, today cheap plastic beadnecklaces from overseas are tossed from floats by the handful. Spectators sometimes pile dozens around their necks, but many are trashed or left on the ground. A few years ago after heavy flooding, the city found more than 46 tons of them clogging its storm drains.

The beads are increasingly viewed as a problem, but a Mardi Gras without beads also seems unfathomable. That is why it was a radical step when the Krewe of Freret made the decision last year to ban plastic beads from their parade.

“Our riders loved it because the spectators don’t value this anymore,” Freret co-founder Greg Rhoades said. “It’s become so prolific that they dodge out of the way when they see cheap plastic beads coming at them."

This year, beads are back, but not the cheap plastic ones. Freret is one of three krewes throwing biodegradable beads developed at Louisiana State University.

The “PlantMe Beads” are 3-D printed from a starch-based, commercially available material called polylactic acid, or PLA, graduate student Alexis Strain said. The individual beads are large hollow spheres containing okra seeds. That is because the necklaces can actually be planted, and the okra attracts bacteria that help them decompose.

Kristi Trail, executive director of the Pontchartrain Conservancy, said plastic beads are a twofold problem. First, they clog the storm drains, leading to flooding. Then those that aren’t caught in the drains are washed directly into Lake Pontchartrain, where they can harm marine life. The group is currently preparing to study microplastics in the lake.

The trend toward a more sustainable Mardi Gras has been growing for years and includes a small but growing variety of more thoughtful throws like food, soaps and sunglasses. Trail said there is no good data right now to say if those efforts are having an impact, but the group recently got a grant that should help them answer the question in the future.

“Beads are obviously a problem, but we generate about 2.5 million pounds of trash from Mardi Gras,” Trail said.

Strain works in the lab of Professor Naohiro Kato, an associate professor of biology at LSU. He first got the idea to develop biodegradable beads in 2013 after talking to people concerned about the celebration's environmental impact. As a plant biologist, Kato knew that bioplastics could be made from plants and got curious about the possibilities.

The first iteration of the lab's biodegradable beads came in 2018, when they produced beads made from a bioplastic derived from microalgae. However, production costs were too high for the algae-based beads to offer a practical alternative to petroleum-based beads. Then Strain started experimenting with 3-D printing, and the PlantMe Bead was born.

For the 2026 Carnival season, LSU students have produced 3,000 PlantMe Bead necklaces that they are giving to three krewes in exchange for feedback on the design and on how well they are received by spectators.

One funny thing, Kato said, is that people have told him they love how unique the PlantMe Beads are and want to keep them.

“So wait a minute, if you want to keep it, the petroleum-plastic Mardi Gras bead is the best, because this won’t last,” he said.

The lab is still working on ideas for a more sustainable Mardi Gras. Strain is experimenting with a different 3-D printer material that biodegrades quickly without needing to be planted. Kato is talking with local schools about turning Mardi Gras bead-making into a community project. He envisions students 3-D printing necklaces while learning about bioplastics and plant biology. And he is still exploring ways to make algae-based bioplastic commercially viable.

Ultimately, however, Kato said, the goal should not be to replace one plastic bead with a less harmful one. He hopes Mardi Gras embraces the idea of less waste.

Rhoades said Freret is moving in the same direction.

“In 2025, we were the first krewe — major parading organization — to say, ‘No more. No more cheap beads. Let’s throw things that people value, that people appreciate, that can be used year-round,’ " Rhoades said.

One of the most coveted items they throw is baseball hats with the Freret logo. He sees people wearing the hats around the city, and he says other krewes have noticed.

“I really believe that we, and other krewes, are able to inspire your larger krewes,” he said. “They want people to like their stuff. They want people take their stuff home, and use it, and talk about it, and post it on social media, and say, ‘Look what I just caught!’ ”

MILWAUKEE (AP) — Giannis Antetokounmpo says he’s healthy and wants to play even as the Milwaukee Bucks continue to say the two-time MVP is too injured to take the floor.

Antetokounmpo missed a 10th straight game on Friday night against the Boston Celtics due to what the team has described as a left knee hyperextension and bone bruise. Antetokounmpo hasn’t played since landing awkwardly during a March 15 victory over the Indiana Pacers.

“I’m healthy,” Antetokounmpo told the Milwaukee Journal Sentinel and The Athletic before Friday’s game. “I hate it when people force me to do things against my nature. I’m a player. I get paid to play.”

For the last couple of weeks, Antetokounmpo has participated in pregame warmups without showing any apparent signs of injury.

Antetokounmpo also noted that the Bucks should have known this about him since the 31-year-old has spent his entire 13-year career in Milwaukee.

Throughout that time, Antetokounmpo has had a reputation for rapid returns from injury, most notably when he hyperextended his knee during Milwaukee’s 2021 playoff run but missed two games before returning to lead the Bucks to their first title in half a century.

“You know who you’re dealing with,” Antetokounmpo told reporters. “So, for somebody to come and tell me to not play or to not compete, it’s like a slap in my face.”

The Bucks still had a remote chance of earning a 10th straight playoff berth at the time of that Indiana game, but they were officially eliminated from contention last week. There’s also the possibility of Antetokounmpo getting hurt again if he returns to action — he has missed a career-high 41 games this season and had two extended absences due to calf strains.

“I understand the circumstances — yes, we’re not going to be in the playoffs,” Antetokounmpo said. “For some people’s eyes, it’s not worth it for me to be out there. But for me, it’s something that goes against my nature.”

Antetokounmpo also wanted the opportunity to play alongside his younger brother, Alex, who made his NBA debut Sunday. There was a possibility of three Antetokounmpo brothers playing alongside each other in the same game, since Giannis’ older brother, Thanasis, also is on the Bucks.

“When my dad passed away, I pretty much raised (Alex),” Antetokounmpo said. “He’s able to be on the team and suit up and chase an opportunity to be great. You really think I don’t want to suit up and play with my brother? Anybody who thinks that is an idiot.”

Antetokounmpo’s desire to play — and the Bucks’ wishes to rest him — drew the attention of the National Basketball Players Association last month.

“The Player Participation Policy was designed by the league to hold teams accountable and ensure that when an All-Star like Giannis Antetokounmpo is healthy and ready to play, he is on the court,” the union said in a statement. “Unfortunately, anti-tanking policies are only as effective as their enforcement; fans, broadcast partners, and the integrity of the game itself will continue to suffer as long as ownership goes unchecked. We look forward to collaborating with the NBA on meaningful new proposals that will directly address and discourage tanking.”

This dispute between Antetokounmpo and the Bucks comes at a time when his future in Milwaukee is uncertain. Antetokounmpo’s name dominated league-wide discussions leading up to the trade deadline, though the Bucks ultimately kept him.

Antetokounmpo becomes eligible to sign a four-year contract extension worth up to $275 million in October. If he doesn’t sign the extension, Antetokounmpo could become a free agent after the 2026-27 season, or the Bucks could decide to trade him beforehand.

Now they find themselves at odds over how to handle the rest of this season.

“I don’t know where the relationship goes from there,” Antetokounmpo said. “We’ve got to go to couples therapy.”
