Abstract
The invention relates to a method of solubilizing expanded polystyrene (EPS), in which the EPS is brought into contact with at least one initial solvent, enabling the transition of the EPS from an expanded solid state to the gel state. The aforementioned gel is subsequently treated with at least one complementary solvent that is different from the initial solvent, enabling the solubilization thereof such as to produce a true solution. The invention also relates to the product thus obtained and to the use of said product.
