This cross-sectional study investigated the innovative use of recycled Styropor as a thermal insulation material, a viable alternative to conventional building materials like concrete blocks and plywood. By addressing concerns regarding Styropor waste, the research intends to enhance energy efficiency and sustainable construction. Comparing the thermal insulation properties of Styropor to those of concrete blocks and plywood, the study investigates effective recycling methods and environmental benefits. Moreover, a laboratory investigation evaluates the thermal conductivity and compressive strength of alternative thermal insulation sheets. The feasibility of Styropor is evaluated based on structural factors, including load-bearing capacity, durability, and long-term stability. The results of this study shed light on the viability of recycled Styropor as a thermal insulation material in construction. The study found that the addition of graphene to three samples had a substantial effect on compressive strength and thermal conductivity. The researchers came to the conclusion that styropor+ graphene oxide could be a new material for shear wall insulation if the appropriate molding procedures, molder types, and ductility tolerance are observed. By reusing Styropor, the construction industry can reduce its environmental impact, conserve natural resources, and improve building energy efficiency. It is suggested that flimsy disintegrating materials provide strength; alternative decorative materials may be manufactured.
