The works devoted to the processing of the pulp and paper industry wastes via environmentally
benign supercritical water conversion are analyzed. The high efficiency of production
of combustible gases above 873 K is demonstrated. Mechanisms of the conjugate
conversion of organic and mineral components of wastes are considered. The main obstacles
to the industrial implementation of the processes under consideration, such as plugging
of pi pelines, salt deposition and corrosion of structural materials, are discussed.
