Technical and economic evaluation of sawdust of different tree species as sorbents for oil products purification

Abstract

The paper analyzes the environmental state of the environment in connection with its pollution by fuels and lubricants (through spills and leaks), as well as the consequences caused by their accumulation in soil and water. It is shown that petroleum products entering the soil and water environment can significantly pollute them. The means, methods, and technologies for cleaning the soil and water environment from oil products and their decomposition products are evaluated. The expediency of cleaning pollution by sorption is substantiated as an effective, simple, affordable method, when sawdust of various tree species is used as a sorbent material at low cost. The article presents the physicochemical, structural, absorption and sorption characteristics of sawdust of different tree species, their advantages and efficiency, in comparison with other sorbents of plant origin, when used for the purification of soil and water environment. The environmental and economic advantages of cleaning the soil and water environment from oil products with sawdust of different tree species in comparison with other cleaning methods are revealed.
