CTO – Crude tall oil


Crude tall oil (CTO) by Stora Enso is a special source of bio-based products. It is extracted from Nordic Softwood – a natural, renewable resource from our sustainably managed North European forests – during the kraft pulping process.

This valuable ingredient of the wood is a mixture of fatty acids, rosin and other neutral compounds. The crude tall oil can be further refined to different fractions like fatty acids, rosins and sterols. These intermediates can be used in a wide variety of applications and products across various industrial and consumer markets. In addition, CTO can be refined and turned into biofuels replacing fossil-based fuels. 


Crude tall oil is a versatile material that maximizes the life cycle of wood-based raw materials. It is a non-land based, non-food competing feedstock. CTO offers an alternative to petroleum- and vegetable-based oils, adding value in products such as detergents and soaps, adhesives, lubricants, paints and coatings, biofuels and much more.

Key benefits:

  • Derived from renewable, sustainable sources.
  • Unique properties with wide variety of industrial and consumer applications.
