In Russia, Mondi has commissioned a crude tall oil plant (CTO-plant) at its Syktyvkar pulp and paper mill. The new equipment allows processing of all sulphate soap generated as a by-product of the pulp production process in the mill. As a result of this investment, the mill will be able to produce up to around 40,000 metric tons of crude tall oil annually.

The new CTO-plant produces softwood and hardwood tall oil obtained through sulphuric acid treatment of sulphate soap which is a by-product of the pulp cooking process. Softwood tall oil is used at Mondi Syktyvkar to mitigate pitch deposits at the digesters, while hardwood tall oil is sold to external companies dealing in petrochemical, road construction, paint and coating. In recent years, tall oil has been intensively used for biodiesel fuel production primarily in Scandinavian countries.
