Industrial ferrous wastes found their application in construction. However, they are mostly stored polluting the environment. In the current work, possibility of value added products synthesis from steel slag with their further use as catalysts was investigated. Slag-based catalysts were obtained by alkaline treatment with sodium hydroxide by variation of synthesis parameters. The physico-chemical properties of the synthesized materials were determined by N

. Alkaline treatment of the raw material promoted creation of mesoporosity and an increase of the surface area. Catalytic fast pyrolysis of pine sawdust displayed variations in the yields of the reaction products in the presence of catalysts as compared to thermal fast pyrolysis.
