Abstract
Waste glass from damaged photovoltaic modules (PV modules) presents a substantial opportunity for recycling into foam glass, offering a valuable product while addressing environmental concerns associated with solar panel disposal. This study aims to evaluate the foaming process of foam glass produced from waste glass and foaming agents by observing the appearance of the samples. The results indicate that excess foaming agent can hinder the interaction between glass particles, limit foaming expansion, and leave residues in the sintered samples. Additionally, the maximum expansion temperature is found to shift to a level higher than the decomposition temperature of CaCO3, attributed to the insufficient viscosity of the glass. This approach paves the way for determining the optimal sintering temperature and provides valuable insights into the foaming process of porous materials.
