Biodegradable Beads Are Helping Mardi Gras Go Green.

This article focuses on efforts to make Mardi Gras celebrations in New Orleans more environmentally sustainable by replacing traditional plastic beads with biodegradable alternatives. Researchers at Louisiana State University developed 3D-printed PlantMe beads made from polylactic acid (PLA) containing okra seeds, which decompose faster in soil and were distributed in limited quantities during the recent Carnival. The open-access design files aim to enable community production through schools and libraries with 3D printers. Additionally, local organizations and Carnival krewes are implementing recycling initiatives and promoting sustainable parade throws to reduce waste. The article highlights the importance of shifting community attitudes toward sustainability as a key factor in reducing environmental impact during Mardi Gras.
