The article presents theoretical background and experimental data on the use of thermally modified waste of the sugar industry – sugar defecate as a black pigment filler in rubber compounds instead of carbon black and chalk. In previous studies, a method for processing calcium carbonate-containing raw material by thermal modification of its surface was suggested. As a result of heat treatment at a temperature of 600°C, a thermolysis sugar defecate TD 600 - a fine black powder - was obtained. It was established that on the surface a layer of carbon (soot) coating CaCO 3 particles is formed. The purpose of this article is to study the possibility of using the thermolysis defecate TD 600 as a pigment-filler in rubber compounds. To establish the possibil-ity of using the TD 600 thermolysis defecate as a pigment-filler and an amplifier of polymer compositions, its physicochemical parameters were studied and compared with traditional pig-ments. A comparative analysis of physicochemical properties of fillers used in rubber com-pounds and thermolysis defecate TD 600 was carried out. Properties of the pigment filler corre-spond to the parameters of materials used in rubber compounds; its oil absorption (80 ml/100g) is similar to that of classic carbon P514. The use of TD 600 a black pigment-filler will solve two problems: saving raw materials and energy and improving the ecological situation.
