The paper is devoted to the study of the use of organic-mineral waste from the pulp and paper industry for the land and dumps restoration disturbed by the mining and processing industry. The examination of the chemical, agrochemical and toxicological properties of the dumps of the Verninsky GOK were carried out. It showed their toxicity to the environment and the need for restoration. It is proposed to use soil moisture obtained from frozen colloidal sediments of sludge-lignin of the Baikal PPM OJSC (BPPM) to intensify the restoration succession. It reduces the toxic effect of dumps on higher plants and introduces the necessary nutrients. At the same time, the use of the obtained soil moistures will make it possible not only to restore lands disturbed by the mining and processing industry, but also to utilize the accumulated waste of JSC BPPM, which creates a huge socio-ecological threat for Lake Baikal and the entire Southern Baikal region.
