IISc Researchers Developed Revolutionary Eco-Friendly Biodegradable Foam

Researchers at the Indian Institute of Science (IISc) have made important strides in sustainable packaging. They have developed a biodegradable foam that offers a promising alternative to traditional plastic materials. This innovation comes at a critical time as environmental concerns intensify. The Indian foam market is projected to grow, denoting the need for sustainable solutions.

Background of the Research

The research team, led by Professors Suryasarathi Bose and Subodh Kumar, aimed to address pressing environmental issues. The current plastic foam production rate is alarming, with less than 1% of the 2.3 million tonnes recycled annually. This new foam could change that narrative.

Unique Chemical Structure

The biodegradable foam features a unique chemical structure. It contains dynamic covalent bonds that can break and reform. This property allows the foam to be mechanically reprocessed or dissolved in eco-friendly solvents. Remarkably, it maintains its strength throughout these processes.

Rapid Disintegration

One of the standout features of this foam is its rapid disintegration. When exposed to eco-friendly solvents at 80°C, it can break down within three hours. This is a stark contrast to traditional materials that can linger in landfills for centuries.

Eco-Friendly Materials Used

The bio-derived foam is made from US FDA-approved non-edible oils and natural hardeners. It combines epoxidized fatty acids with polyphenol-based hardeners sourced from tea leaves. This makes the foam entirely eco-friendly and safe for various applications.
