• i) receiving a tobacco material comprising at least one of a stalk material and a root material of a harvested plant of the Nicotiana species;
• ii) pyrolyzing the tobacco material to remove volatiles and to form a tobacco-derived carbon material;
• iii) activating the tobacco-derived carbon material;
• and
• iv) incorporating the activated tobacco-derived carbon material into a tobacco product, wherein the tobacco product is a smoking article, wherein the smoking article comprises a filter element, and wherein the activated tobacco-derived carbon material is located within the filter element;
• wherein the tobacco material comprises at least about 90 percent by dry weight of the root material of a harvested plant of the Nicotiana species;
• and
• wherein the tobacco-derived carbon material comprises an ash content of about 5% or less by dry weight.
