Controlling the release of wood extractives into water bodies by selecting suitable eucalyptus species

► Water usage and environment pollution by pulping mills depend on wood materials. ► The amount of extractives in eucalyptus woods vary with tree species and sites. ► Eucalyptus grandis is attractive for pulping for minimal water and environment pollution. ► Ixopo site produce trees with higher amount of extractives, hence not suitable site. ► Fatty acids were responsible for the differences in the tree species studied.
