Mardi Gras provides about $5.1 billion to the economic system of the state of Louisiana — but additionally produces large quantities of trash, together with virtually 1,300 tons within the metropolis of New Orleans alone, with tens of 1000’s of kilos consisting of plastic Mardi Gras beads.
Now, researchers at Louisiana State College (LSU) have developed biodegradable Mardi Gras beads, produced from algae, that they are saying might assist cut back pageant waste at Mardi Gras and festivals around the globe.
Purple, Gold, and Algae Inexperienced
LSU Division of Organic Sciences professor Naohiro Kato had already been contemplating methods to make Mardi Gras extra environmentally pleasant when a tube of algae uncared for by a lab scholar started producing oils utilized in bioplastic manufacturing.
From that place to begin, Kato developed a course of by which a microscopic species of algae may very well be grown, harvested, and floor right into a high quality powered able to forming throw beads and plastic doubloons.

To be truthful, the method continues to be prohibitively costly.
By Kato’s estimations, the primary batch of biodegradable beads might value as a lot as $40,000 for three,000 necklaces, about $13 per necklace. Kato hopes that optimizing the method might cut back the associated fee to as little as $1 or much less per necklace — although producing at scale would require algae ponds the scale of soccer fields.
One potential answer: Kato believes there could also be a collaborative tie-in with Lousiana’s crawfish and aquaculture industries.
Festivals and celebrations produce massive quantities of extra waste. A 2017 research discovered that main music festivals, like Coachella, produce virtually 107 tons of waste, a lot of which fits unrecycled or sits in landfills for tons of of years.
Against this, biodegradable pageant tchotchkes comprised of Kato’s course of degrade within the soil in about one to 2 years. The brand new utility of expertise to pageant tradition might allow us all to have a bit extra enjoyable with rather less guilt.
“I consider we will change and do higher,” Kato mentioned. “We’ve got nice assets to make our Mardi Gras celebrations extra sustainable and to guard the environment and well being.”
