Cigarette butt bricks

  1. 1. Seminar On Cigarette Butt Bricks
  2. 2.  Over a million tonnes of cigarette butts (CBs) are produced worldwide annually.  CBs accumulate in the environment mainly due to the poor biodegradability of the cellulose acetate filters.  CB filters release a range of toxic chemicals as they deteriorate.
  3. 3.  CBs are carried by stormwater into watercourses and ultimately the ocean where the chemicals they contain pose a risk to the organisms of both freshwater and marine environments.  Recycling CBs is problematic because there are no easy mechanisms or procedures to assure efficient and economical separation and recycling of the entrapped chemicals.  An alternative could be to incorporate CBs in a sustainable composite building material such as fired bricks.
  4. 4. Mixture Identification % of CBs by wt. of Bricks CB(0.0) 0 CB(2.5) 2.5 CB(5.0) 5.0 CB(10.0) 10.0
  5. 5.  Firstly clay is prepared and the amount of CBs are added to it by the total weight of Bricks in %  Then this clay is placed into a brick mould and is well compacted.
  6. 6.  Then it is removed from the mould and is allowed to dry for 2-3 days.  After that the bricks are burned in a kiln until it gets reddish brown at a temperature 900 to 1200 degree celsius.  The Brick is then allowed to cool down for two to three days.
  7. 7.  Compressive Strength Test  Water Absorption Test  Flexural Strength Test
  8. 8. Mixture Identification Compressive Strength (Mpa) Flexural Strength (Mpa) Water Absorption (%) CB(0.0) 25.65 2.79 5 CB(2.5) 12.57 2.48 9 CB(5.0) 5.22 2.40 15 CB(10.0) 3.00 1.24 18
  9. 9.  Reduces Pollution upto certain extent.  Water Absorption & Compressive Strength of Bricks is not much affected if % of CBs is upto certain limit.  Alternative for Conventional Clay Brick.  It controls the effect of CBs on Marine life.  It solves the problem of disposal of CBs.
