    Abstract: The present invention relates to a method for producing lignin in particle form from a liquid containing lignin-containing raw material, the method comprising at least: reacting the liquid with a cross-linking agent (step a)), precipitating the lignin, thereby forming lignin particles in the liquid (step b)), and separating the liquid from the lignin particles formed in step b) (step c)), and wherein, in step b), the liquid is heat-treated, after precipitation, at a temperature in the range of 60 to 200° C. for a period of 1 minute to 6 hours, and/or, in an additional step d) after step c), the lignin particles separated from the liquid are heat-treated at a temperature in the range of 60 to 600° C. The invention also relates to lignin particles which can be obtained according to the method, lignin particles per se, a use of the lignin particles as filler, and a rubber composition comprising, inter alia, a filler component, the latter containing lignin particles as a filler.
