The present invention relates to a rubber composition comprising a rubber component comprising at least one halogenated butyl rubber in an amount of from 60 phr to 100 phr and a filler component comprising a filler F1 having a 14C content in the range of from 0.20 Bq/g carbon to 0.45 Bq/g carbon, a carbon content in the range of from 60% by weight to 85% by weight and having acidic hydroxyl groups on the surface; wherein the weighted arithmetic mean of the STSA surface area of the filler F1 is in the range of 40 m2/g to 80 m2/g; the filler F1 has a volume-based median particle size distribution Dv (50) in the range of 0.5 [mu] m to 5 [mu] m and a volume-based Dv (97) value in the range of 3 [mu] m to 23 [mu] m; and (i) the filler component comprises more than 45 phr of a filler F1; or (ii) the filler component comprises more than 25 phr of a filler F1 and additionally comprises one or more industrial carbon black F2 wherein the weighted arithmetic mean of the STSA surface area of the industrial carbon black F2 is in the range of 55 m2/g to 95 m2/g. The invention also relates to vulcanizable and vulcanizable rubber compositions based on the aforementioned rubber composition, to a kit for preparing a vulcanizable rubber composition, and to a method for preparing a rubber composition and vulcanizable rubber composition. In addition, the present invention relates to a method of further processing a vulcanizable rubber composition. The invention also relates to application of the lignin subjected to hydro-thermal treatment in preparation of a rubber composition for a lining.
