The properties and main characteristics of the large-tonnage waste of industry - hydrolytic lignin, as well as the direction of its rational use are considered. The results of an experiment on the effect of the lignin of the Kosivinsk hydrolysis plant on the main properties of the cement-sand composition are presented. It is shown that the addition of hydrolytic lignin in an amount of 15-20% by mass in exchange for the binder will yield a building material with a mark of average density D1900-D2000 and a class of compressive strength B5-B7.5.

Keywords: hydrolytic lignin, waste, low-rise construction, wall material, secondary raw materials, utilization
