HOW IT WORKS The process – from pine to product 01 Tall oil RENEWABLE RAW MATERIAL Black liquor soap - a sidestream Pulpwood is delivered to pulp mills and is chipped from the kraft pulp process - is and boiled in white liquor; the fibres are filtered out converted to crude tall oil. We to become paper pulp. capture the valuable substances contained in tall oil and turn them into specialty chemicals in our
biorefineries. FROM BLACK LIQUOR SOAP TO TALL OIL The digester liquid left once the fibers have been filtered out is called black liquor. Soap is recovered from the black liquor. Crude tall oil is extracted from the soap in a separate process and later sold to the pine chemical industry.
TIME FOR SEPARATION 02 The tall oil is pumped into our bio-refinery. Here it is slowly heated under vacuum and then separated into four different parts – tall Processing oil fatty acid, tall oil rosin, distilled tall oil and THE LAB tall oil pitch. In the lab, frequent We distill tall oil to extract measurements and tests check the quality of our products.

We call these fractions. 03 Product development The fractions are refined and upgraded into a wide range of biobased specialty chemicals. These are sold to customers that seek superior product performance.
