FIELD: waste disposal.
SUBSTANCE: invention is related to disposal of polymer composite materials, which makes it possible to obtain a solvolysis liquid and a reinforcing filler, which can subsequently be used to create new polymer composite materials. Utilization is carried out by thermal treatment of polymer composite materials in methyldiethanolamine in presence of caustic soda at a temperature of 180°C.
EFFECT: invention makes it possible to reduce energy consumption for implementation of the process, as well as to reduce the solvolysis temperature, which makes it possible to preserve the strength properties of glass fibre to a greater extent.
