The document describes a student project to coat asbestos roofing with polystyrene to reduce heat absorption and promote recycling of polystyrene. The student dissolved polystyrene in benzaldehyde to create a paint and coated an asbestos roof. Temperature measurements found a 6 degree Fahrenheit reduction under the coated roof, demonstrating reduced heat penetration. The student concluded that coating asbestos with polystyrene helped create a more eco-friendly environment by recycling polystyrene and reducing heat absorption by the roof.
