<p>The method involves separating lignin and/or lignin derivative from a lignin waste product. A mixture of the lignin and/or lignin derivative is prepared under a mixture of fabric, where the mixtures are extruded at a plate that is deep-drawn at a molded part. The mixture of the lignin and/or lignin derivative is introduced in a granulated form part, where thickness of the plate is provided is of 2-10mm. Lignin sulfonic acid, alkali-lignin or organic lignin are reacted on the lignin derivative.</p> |
