The problem of the influence of the contents of the sedimentation maps of the Baikal Pulp and Paper Mill on the ecological situation in the Baikal region is considered. Data on the com-position and properties of the contents of the drives are given. The factors threatening Lake Baikal are highlighted. Geographical and seismic characteristics of the locality of the dislocation of objects of environmental danger are given

Variants of modification of technical lignins for the production of drilling reagents in demand in various technological operations during the construction of wells are considered

The variants of using the contents of the sedimentation maps of the Baikal pulp and paper mill in order to improve the ecological situation in the Baikal region are considered. It is shown that sludge-lignin can be used as a raw material to produce a variety of products

The reasons for the accumulation of man-made waste during the years of operation of the Baikal Pulp and Paper Mill, as well as the history of construction and filling of storage facilities with waste, in particular sludge-lignin, are considered

The urgency of creating thermo- and salt-resistant reagents for drilling wells is shown. Some methods of obtaining such additives from modified technical lignins are considered
