If you’ve never been to a Mardi Gras parade in New Orleans, the volume is hard to picture. A medium-sized parade — say a krewe like Endymion or Bacchus — distributes around three to five million plastic beads in a single night. Multiply across the dozens of parades that run from Twelfth Night through Fat Tuesday, and the city’s annual bead total lands around 25 million pounds. That’s pounds. Of plastic. Thrown from floats, caught by crowds, dropped in gutters, stomped into the asphalt, or left in attics for the next thirty years.

For most of the modern history of Mardi Gras throws, this was treated as an unavoidable cost of the celebration. The beads were cheap, the tradition was beloved, and nobody at the krewe-organizing or city-services level had a real alternative to suggest. That’s changed. Compostable bead alternatives have existed in pilot form for several years and in commercial volumes for a few. A small but growing slice of the New Orleans Mardi Gras community is using them.
This is the actual state of the alternatives — what works, what doesn’t, and what’s stopping the change from happening faster.
The Plastic Bead Problem in Concrete Numbers
The standard Mardi Gras bead is a polystyrene or PVC string, typically manufactured in Wuhan, China, and shipped through Houston or New Orleans ports in massive container loads. Per-bead cost to a krewe is in the range of $0.05 to $0.30 depending on size, complexity, and design. Annual import volume into Louisiana for parade throws sits around 25 to 50 million pounds.
Three problems compound:
Heavy metals. A 2018 study by Louisiana State University’s Department of Environmental Sciences tested hundreds of bead samples and found high concentrations of lead and bromine in a substantial fraction. The lead came from contaminated recycled plastic feedstock; the bromine from flame retardants. Both leach into soil and waterways when the beads degrade in the environment.
Storm drain clogging. New Orleans’s Department of Public Works has run aggressive drain-clearing operations after Mardi Gras for years. In 2018, a single 5-block stretch of St. Charles Avenue yielded 93,000 pounds of beads pulled from drains. Citywide totals run into the millions of pounds annually. Clogged drains contribute to the flooding the city is already vulnerable to.
End-of-life. The beads catch in gutters, trees, fences, and landscaping for years after the parade. They don’t biodegrade. They fragment into microplastics. They show up in soil samples, in waterway sediment, and eventually in the Gulf of Mexico. Recycling rates for Mardi Gras beads are essentially zero — the mixed materials, contamination, and low per-pound resin value make them economically unrecyclable.
This is the problem the compostable alternatives have to solve.
The Algae Bead Project
The most-publicized compostable alternative came out of LSU. In 2018, biology professor Naohiro Kato published research on bead alternatives made from microalgae. The chemistry uses biopolymers extracted from microalgae cultivation as the bead material. The result is a bead that biodegrades fully in soil within months under composting conditions.
The project has received steady press coverage but has scaled slowly. Production cost remains higher than plastic. Throughput from algae-cultivation systems doesn’t yet match the millions-of-beads volume that a single major krewe distributes per parade. The beads are also lighter than traditional plastic, which changes how they throw and how they feel when caught — small but meaningful differences for parade-goers who are used to specific bead behavior.
As of recent reporting, algae beads are available in pilot quantities, used selectively by smaller krewes and sustainability-minded throw organizers. They aren’t yet a wholesale replacement for the plastic supply chain, but they’re real, they work, and they prove the concept that bead production can be biological rather than petrochemical.
Paper Beads
The simplest compostable alternative is paper. Paper beads are made by rolling triangular strips of recycled paper around a thin spindle, gluing the end, and sealing with a non-toxic varnish. They’ve been a folk-craft staple in East Africa, Uganda specifically, for decades — sold to international fair-trade markets as jewelry.
For Mardi Gras, paper beads have several advantages:
- Genuinely compostable in any composting condition
- Lightweight and safe to throw
- Low manufacturing cost, especially when produced at scale
- Visually distinctive — patterned paper produces beads with character
- Made from waste paper (recycled magazines, newspaper, packaging)
Disadvantages:
- Less durable than plastic; rain or humidity damages them
- Fewer reuse cycles before degradation
- Smaller production capacity globally — no manufacturer is set up for 25 million pounds annually
- Visual aesthetics differ from the metallic-shine of plastic beads
A handful of New Orleans makers have started producing paper Mardi Gras beads at small scale. Etsy listings, local craft fairs, and some krewe partnerships have begun. The supply is artisanal rather than industrial, which limits how widely they can be deployed.
Seed and Plant-Material Beads
Several start-ups and individual makers have produced beads from acai seeds, jacaranda pods, dried legume seeds, or natural wooden cylinders. These are fully compostable, often visually striking, and culturally interesting (some draw on Brazilian, West African, or Caribbean bead-making traditions).
The challenges:
- Production capacity is small
- Cost per bead runs significantly higher than plastic
- Sourcing the raw material at New-Orleans-parade scale is a logistical bottleneck
- Some seed materials require treatment to prevent germination or pest issues
Where they fit: premium throws for VIPs, riders’ personal beads to gift to family, smaller krewes willing to pay more for distinctive throws. Not a primary-volume replacement for the bulk plastic stream.
PHA and Bioplastic Beads
A newer category uses PHA (polyhydroxyalkanoate) or PLA (polylactic acid) as the bead material. These are bioplastics — petroleum-replacement polymers derived from sugar, corn starch, or microbial fermentation.
PHA-based beads have the most interesting profile: they biodegrade in marine environments, in industrial composting, and even in home composting given enough time. PLA beads biodegrade only in industrial composting conditions.
Both can be molded to look and feel similar to traditional plastic beads. Manufacturing setup is more familiar to existing bead production lines than algae or paper alternatives. The cost is higher than petroleum plastic but coming down with scale.
Several startups have prototyped PHA Mardi Gras beads. Mass commercial deployment hasn’t happened yet at the scale of the major krewes, but the technical feasibility is established.
What Krewes Are Actually Doing
The honest assessment of New Orleans krewe behavior:
Most major krewes still throw primarily plastic beads. The volume requirements, the pricing pressure, and the inertia of decades of established supply chains make full transitions slow.
A growing minority of krewes have introduced sustainable throws as a portion of their distribution. Some include compostable beads, biodegradable cups, or wooden doubloons alongside traditional plastic. Krewe of Freret has been notable for sustainable-throw initiatives. Several parade clubs have introduced “krewe of throw me something compostable” branding as a small marketing-and-mission combination.
A few small krewes have committed to all-sustainable throws. Walking groups, neighborhood marching clubs, and smaller parading organizations have shifted entirely to compostable, paper, plant-based, or refillable throws. The Krewe of Tucks, the Krewe of Red Beans, and several others have made meaningful progress.
Riders increasingly buy their own sustainable throws. Individual float riders who want to do the right thing buy compostable beads or alternative throws (decorated bandanas, paper masks, painted wooden tokens) for their personal distribution. This is bottom-up adoption rather than krewe-mandated.
The change is happening. It’s incremental. It’s not yet at the volume scale where the city’s bead-waste problem is materially reduced. But it’s real and measurable.
The Throw Categories That Aren’t Beads
Worth noting that not all Mardi Gras throws are beads. The traditional throw mix includes:
- Beads (the dominant category)
- Doubloons (aluminum or wooden coins)
- Plush toys (small stuffed animals — increasingly seen as wasteful)
- Plastic cups (often compostable now in many krewes)
- MoonPies (Endymion’s signature throw, edible)
- Specialty hand-crafted items (the Muses’ shoes are famous)
- Toilet paper rolls (Krewe of Tucks)
- Decorated coconuts (Zulu Coconuts, hand-decorated)
Compostable alternatives are easier in some categories than others. Plush toys, for instance, are difficult to produce in compostable form without losing the toy quality kids expect. Specialty hand-crafted items often already use natural materials.
For the broader category of party and event disposables that surround Mardi Gras parties at home — hosting watch parties, neighborhood gatherings — replacing plastic cups, plates, and utensils with compostable plates, compostable cups and straws, and compostable utensils is much easier than replacing the parade throws themselves. The party-supply category has mature compostable alternatives at scale; the parade-throw category is still building.
What’s Stopping the Change
Three real obstacles to faster transition:
Cost. Compostable beads run 3-10x the per-bead cost of plastic beads. For a krewe distributing millions of beads, the math is uncomfortable. A million-bead parade at $0.10 plastic vs $0.40 compostable means a budget delta of $300,000 per parade.
Volume. No single compostable manufacturer can supply a major krewe’s annual throw volume. Plastic supply chains have been built up over fifty years. Compostable alternatives are at startup or small-mid-scale capacity.
Tradition. Mardi Gras beads have a specific look, feel, and weight that parade-goers are used to. Catching a “weird-feeling” bead can disappoint. Krewes that have built their identity on specific throw styles are reluctant to change for fear of fan reaction.
Information asymmetry. Many krewe captains and ride-leaders simply don’t know that compostable alternatives exist. The information gap between sustainable-bead makers and large-scale throw buyers is substantial.
The first three obstacles are solvable with scale. The fourth requires sustained outreach from the alternative-bead community to krewe leadership.
How to Buy Compostable Beads
For individual riders or small groups looking to buy compostable Mardi Gras throws:
Local New Orleans makers: several artisans now produce paper, wooden, or seed-based beads in small batches. Etsy, local craft fairs, and pop-up markets during the Mardi Gras season are good sourcing channels. Quality varies but is generally good.
Algae beads: when available, typically through LSU-related research distribution or specialty sustainability outlets. Quantities are limited.
PHA / PLA beads: through emerging bioplastic specialty suppliers. Typically requires a wholesale order rather than retail purchase.
International paper bead artisans: Ugandan paper bead cooperatives ship internationally and can supply moderate quantities. Quality is high; lead times are long.
Recycle Your Beads programs: an alternative is to rely on recycling. ARC of Greater New Orleans runs a program where they collect and re-sell used beads. Buying from ARC supports their disability-employment mission and reduces demand for new plastic. Not strictly compostable, but extends the lifecycle of existing material.
For most riders, a mix of recycled-bead reuse (cheap, supports a cause) plus a smaller premium throw of compostable or hand-made beads (distinctive, sustainable) is the working balance.
The Quiet Direction
Mardi Gras itself isn’t going to stop. Nor should it — the parades are one of the country’s most distinctive cultural traditions, and the bead-throwing is central to the experience. The change that’s happening is in the materials, the supply chain, and the assumptions about what a throw has to be made of.
A decade from now, the mix is likely to include:
- A reduced plastic-bead majority (cheap volume, used by traditionalist krewes)
- A growing compostable-bead minority (algae, PHA, paper)
- A continued specialty-throw tradition (wooden doubloons, decorated items, hand-crafted gifts)
- More aggressive recycling and reuse programs
- Better post-parade collection infrastructure
- Tighter regulation on heavy-metal contamination in imported beads
Whether the compostable alternatives ever become the volume majority depends on price competition, manufacturer scale, and krewe willingness to lead. The trajectory is positive but slow.
For now, what’s worth knowing is that the alternatives are real. If you ride in a krewe and want to throw something that doesn’t outlast your great-grandchildren, you can. If you watch a parade and want to choose what you bring home, you can pick up compostable beads from a maker who’s selling them. The plastic bead is the default, not the only option.
That distinction — default versus only — is where most sustainability transitions actually happen. Mardi Gras is no exception. The compostable bead is real. The supply is small but growing. The rest follows when enough riders, krewes, and parade-goers start asking for it.
Verifying claims at the SKU level: ask suppliers for a current Biodegradable Products Institute (BPI) certificate or an OK Compost mark from TÜV Austria, and check that retail-facing copy meets the FTC Green Guides qualifier requirement on environmental claims.
