Abstract: The article is devoted to the use of chemical dispersion technology during the underwater oil pipelines accidents in the Arctic. Dependences of dispersion efficiency on salinity, viscosity, temperature and limitations of the use of dispersion depending on environmental conditions are given. The actuality of the use of underwater dispersion in the Arctic conditions is considered

Abstract: The work considers reagent encapsulation as one of the most promising technologies of sludge, drill cuttings and other waste disposal. The recommendations of foreign and Russian researchers to implement this method of waste processing are presented. The results of experimental work on the selection of recipes of neutralizing reagent encapsulation method are presented: the existing recommendations were tested; an additional agent – the fly ash of thermal power plants  was used in the treatment. The recommendations for the disposal of various wastes are formulated more implicitly.
