Regenerated cellulose xerogel from plant biomass waste for sustainable frozen food packaging

Overview

This solution offers a sustainable, biodegradable packaging material made from regenerated cellulose xerogel derived from plant biomass waste, including kenaf core and oil palm empty fruit bunch fibers. The material is designed for frozen food packaging applications, providing enhanced mechanical strength, reduced weight, and effective thermal insulation compared to conventional packaging materials.

By converting agricultural waste into a high-performance packaging material, this innovation addresses two challenges simultaneously: reducing the environmental burden of plastic packaging and adding value to biomass waste streams. The approach aligns with Sustainable Development Goals (SDGs) by promoting a green, biodegradable, and biocompatible alternative for the frozen food industry. Potential benefits include improved frozen food preservation, reduced environmental impact, more efficient transportation due to lighter packaging, and positive economic implications for both packaging manufacturers and food producers.
