Представлены результаты изучения вещественного состава проб шлаков двух объектов термической переработки твердых коммунальных отходов (ТКО) и золы-уноса комплексом минералого-аналитических методов. Установлены особенности фазового состава шлаков, определены возможные направления их утилизации. Показано присутствие фаз, потенциально активных для ускоренной карбонизации в технологии связывания диоксида углерода. Представлены результаты расчета величины изобарно-изотермического потенциала реакций гидратации и карбонизации шлаковых фаз. Для предварительной количественной оценки поглощения CO₂ остатками от сжигания ТКО выполнен расчет по формуле Стенуара, позволяющий установить максимально возможную улавливающую способность. Установлена теоретическая возможность связывания газообразного диоксида углерода изученными шлаками и золой с переводом их из химически активной в термодинамически стабильную карбонатную форму.
