Abstract Majority of wood processing technologies prescribe preliminary peeling of raw materials – in this way woodchip for cellulose production are made. The chemical composition of bark is different for each tree species. Mainly polymeric components in barks are lignin and cellulose. Bark, in comparison with wood, contains more lignin, less cellulose. High lignin content, submicroscopic structure of bark and properties of new amino product guarantee good properties of physical and chemical sorption. A new effective lignin based material – bark, chemically modified with amino groups could be used in agriculture and gardening as fertilizer and mulch and to solve pollution problems of industrial waste water.
