A flue-curing apparatus and a related method are provided. The flue-curing apparatus includes a circulation chamber and a curing chamber that are separated by a divider wall. An air circulation system includes a blower positioned in the circulation chamber that directs air to a heater device and a lower passage into the curing chamber. The air may be received from one or both of an inlet and an upper passage extending from the curing chamber to the circulation chamber. A humidity control system humidifies the air directed into the curing chamber. A controller may receive signals from wet and dry bulb thermometers to determine the conditions in the curing chamber and the condition of tobacco leaves being cured therein. The controller may adjust various operational parameters to cause the tobacco leaves in the curing chamber to cure at a desired rate.

A biodegradable bi-component fiber may include a polyhydroxyalkanoate and/or polylactic acid with cellulose acetate and/or plasticized cellulose acetate for use in a filter material configured for use in a filter of a smoking article. The bi-component fiber may have a sheath-core construction where one component of the bi-component forms the core, and the other component forms the sheath of each fiber. A filter made in accordance with this design may also include non-biodegradable material.
