Sustainable nanocellulose coating for EPS geofoam extracted from agricultural waste.

Expanded polystyrene (EPS) geofoam blocks are gaining acceptance across industries due to their low density, insulation properties, strength, compressibility, and shock absorption under dynamic loads. The effective application of EPS is impeded by restrictions imposed by using conventional polymer-based synthetic geomembrane insulation ought for protection. Meanwhile, the production process of the geomembrane has detrimental environmental impacts, incurs high costs, and limits the utilization of EPS blocks in various applications.
