Researchers from the Indian Institute of Technology (IIT) Roorkee have made a significant breakthrough in sustainable packaging by developing Kodo millet-based edible cups. This innovation utilizes guar gum and hibiscus powder to improve the structural integrity and functionality of the cups, offering a promising eco-friendly alternative to conventional plastic packaging.

This research, led by Bhushan P. Meshram and Prof. Kirtiraj K. Gaikwad, was recently published in the prestigious journal ACS Food Science & Technology. The study emphasizes using Paspalum scrobiculatum (Kodo millet), a drought-resistant and underutilized grain, to create durable, biodegradable cups that reduce plastic waste and promote environmental sustainability.

Key Highlights of the Research:
Eco-Friendly Materials: The edible cups incorporate natural polymers like guar gum and hibiscus extract to enhance mechanical strength and biodegradability.
Sustainable Innovation: This project supports the circular economy by reducing plastic consumption and offering a compostable solution for food packaging.
Enhanced Functionality: The combination of natural additives increases the cups' resistance to moisture and improves their overall durability.

“Our goal is to provide a practical, sustainable alternative to single-use plastic packaging while utilizing underutilized crops like Kodo millet,” said Bhushan P. Meshram, the lead researcher. “These edible cups are not just environmentally friendly—they are also safe for consumption and biodegradable, minimizing long-term environmental harm.”

The research has already received significant attention. Since its publication, the article has garnered 257 views and achieved an Altmetric score of 3, reflecting the growing interest in sustainable packaging solutions.

Real-World Impact:

The Kodo millet-based cups align with global sustainability initiatives and provide industries with a viable option to transition away from plastic. These cups are particularly valuable in the food and beverage sector, where single-use plastics are a major environmental concern.

In addition to its scientific significance, the research was recently highlighted in The Times of India, further underscoring its potential impact on the industry and the environment.
