A sustainable smoking article element

Abstract

An element for use in a smoking article, the element comprising a longitudinally extending core; wherein the longitudinally extending core comprises a filtering material; wherein the filtering material comprises a paper and/or other biodegradable material; and wherein the filtering material further comprising a hydrophobic material.

1 . An element for use in a smoking article,
 the element comprising a longitudinally extending core;   wherein the longitudinally extending core comprises a filtering material;   wherein the filtering material comprises a paper and/or other biodegradable material; and   wherein the filtering material further comprising a hydrophobic material.   
     
     
         2 . The element according to  claim 1 , wherein the element is a cooling element. 
     
     
         3 . The element according to  claim 1 , wherein the paper and/or other biodegradable material is readily biodegradable. 
     
     
         4 . The element according to  claim 1 , wherein the hydrophobic material is distributed throughout the longitudinally extending core of the element. 
     
     
         5 . The element according to  claim 1 , wherein the filtering material is a paper and/or other biodegradable material with a hydrophobic material coated thereon. 
     
     
         6 . The element according to  claim 5 , wherein the coated paper and/or other biodegradable material is arranged within the longitudinally extending core such that the hydrophobic material is distributed throughout the longitudinally extending core of the element. 
     
     
         7 . The element according to  claim 1 , wherein the longitudinally extending core has one, or a plurality of, longitudinally extending bore(s). 
     
     
         8 . The element according to  claim 1 , wherein the length of the element is from 5 to 50 mm, e.g., 10 to 30 mm, e.g., 8 to 24 mm, e.g., 15 to 20 mm, e.g., 18 mm. 
     
     
         9 . The element according to  claim 1 , wherein the circumference of the element is from 12 mm to 30 mm, e.g., 15 mm to 28 mm, e.g., 17 mm to 25 mm. 
     
     
         10 . The element according to  claim 1 , wherein the longitudinally extending core has a profiled outer surface including a plurality of grooves or channels. 
     
     
         11 . The element according to  claim 1 , wherein the longitudinally extending core has a profiled outer surface including a plurality of grooves or channels and has one, or a plurality of, longitudinally extending bore(s). 
     
     
         12 . A smoking article (e.g., tobacco heating product, HNB product) comprising an element according to  claim 1  and optionally one or more discrete further segments. 
     
     
         13 . A tobacco heating product and/or HNB product comprising an element according to  claim 1  and optionally one or more discrete further segments. 
     
     
         14 . The use, in a tobacco heated product and/or HNB product, of an element according to  claim 1 .
