Estimating the term…
A degradable smoking article comprises a tobacco rod and a filter component made of a gathered web of moisture disintegrative sheet material wrapped with a moisture disintegrative plug wrap bonded along a longitudinal seam with a water soluble adhesive. A moisture disintegrative tipping paper coated on one side with a water soluble adhesive secures the tobacco, rod and filter component together. The combination of moisture and other natural elements such as sunlight, mechanical abrasion, etc., dissociates the components of the smoking article over a relatively short period of time. Other embodiments of the filter component include a hollow degradable tube and a monolithic extruded starch filter rod.
