This article discusses issues related to correcting the adhesive properties of composite materials based on organic waste and expanded polystyrene. The theoretical prerequisites for the formation of the structure of materials based on organic raw materials are determined. An average series of binders has been established as the adhesive strength with vegetable filler increases. The results of determining the adhesive strength of polystyrene foam in the structure of the composite material are presented. In order to increase the hydrophilicity of polystyrene foam, such binders as polyvinyl acetate emulsion, liquid glass, and acrylic latex were used in research. Analysis of the results obtained allows us to evaluate the effectiveness of the binder and determine the optimal type of filler in the composition of the composite material, based on the values of the shear strength. As a result, it was found that the introduction of expanded polystyrene into the composition of a composite material based on organic raw materials makes it possible to reduce the consumption of the binder by 82–87% due to its treatment with an aqueous solution of dimethyl ketone and providing it with adhesive ability. Thus, it is possible to significantly increase the share of organic waste used in the production of building materials, increasing the efficiency of their processing and disposal.
