Researchers at Louisiana State University have developed biodegradable Mardi Gras beads as a sustainable alternative to traditional plastic beads. Mardi Gras, a popular holiday celebrated in New Orleans and other cities in the U.S., is known for its festive parades and parties leading up to the Christian Lenten season. The holiday, which originated as a religious observance, has evolved into a weeks-long celebration with traditions like king cake and colorful bead necklaces.
Mardi Gras in 2025 falls on March 4, with festivities including parades and celebrations occurring throughout New Orleans. The holiday, also known as Fat Tuesday, is rooted in pagan spring and fertility rites and is celebrated in countries with large Roman Catholic populations. Louisiana, with its French and Cajun influences, has a strong tradition of Mardi Gras celebrations.
In New Orleans, Mardi Gras parades will take place on March 4, March 9, and March 15, with a variety of events and activities scheduled throughout the city. The research team at LSU hopes that their biodegradable beads will help reduce waste and environmental impact associated with traditional plastic beads, providing a more sustainable option for future Mardi Gras celebrations.
