Visakhapatnam – In a significant stride toward sustainable packaging and circular dairy economy, Dr Rasheeda Khanam, a researcher at Gitam Deemed to be University, has secured a patent for a novel biodegradable bioplastic derived from dairy waste, specifically ghee residue.
♻️ Bioplastic from Dairy Byproduct: A Game-Changer
The patented innovation repurposes ghee residue—a byproduct typically discarded during clarified butter production—into an eco-friendly, flexible, and compostable packaging material.
Through chemical characterisation and formulation trials, she developed a process combining:
- Ghee residue extract – primary matrix
- Glycerol – for elasticity
- Beeswax, chitin, and zein protein – for strength, hydrophobicity, and durability
The result? A biodegradable bioplastic with remarkable environmental properties:
| Feature | Details |
|---|---|
| Decomposition in Water | Within 24 hours |
| Decomposition in Soil | 20–30 days |
| Applications | Dry food packaging, agricultural products |
| Toxicity | Non-toxic, phenolic compounds preserve food |
| Compostability | Converts into usable fertilizer |
| Chemicals Used | None; 100% natural formulation |
| Patent Status | Granted |
🌍 A Timely Innovation Amid India’s Dairy Waste Challenge
India is the largest producer of milk globally, generating enormous quantities of ghee and subsequently tons of ghee residue, most of which is wasted or dumped in fields. This poses both environmental and logistical challenges for dairy cooperatives, private dairies, and food processors.
The project aligns with global sustainability goals and government-led initiatives, such as the Swachh Bharat Abhiyan and the Plastic Waste Management Rules (Amended) 2022, reinforcing India’s commitment to eco-friendly dairy practices.
🚀 Current Applications and Future Directions
Dr Rasheeda’s team is currently piloting the bioplastic for grain and agricultural packaging. Early trials have demonstrated high tensile strength and moisture resistance, making it a viable option for various food products.
Planned subsequent phases of research include:
- Seafood packaging trials
- Application for non-agro industrial goods
- Collaboration with dairy cooperatives for raw material sourcing
- Scaling up for commercial manufacturing
🌱 Why This Matters to the Indian Dairy Industry
This innovation is more than just a green breakthrough—it touches several critical dimensions of the Indian dairy value chain:
- Dairy waste upcycling
- Eco-friendly dairy packaging
- New revenue streams for ghee manufacturers
- Support for India’s ban on single-use plastic
- Boost to rural circular economy
