| description | Several trillion cigarettes are produced worldwide annually, resulting in tonnes of cigarette butt waste. Cigarette butts
accumulate in the environment due to the poor biodegradability of the cellulose acetate filters. Results from a study on
recycling cigarette butts into fired clay bricks are presented. Five different soil–cigarette butts mixes with different
percentages of cigarette butts were used. The physico-mechanical properties of manufactured bricks including
compressive strength, flexural strength, density, water absorption and thermal conductivity are discussed. The results
show that the density of fired bricks was reduced significantly, by up to 30%, depending on the percentage of cigarette
butts incorporated into the raw materials. Similarly, the compressive strength of bricks decreased according to the
percentage of cigarette butts included in the mix, and the estimated values of thermal conductivity were also reduced
significantly. The results also show that the mixing time has a considerable effect on the properties of the fired clay
bricks tested. Furthermore, the leachate test results revealed only trace amounts of heavy metals. It was concluded that
cigarette butts can be regarded as a potential addition to the raw materials used in the manufacture of lightweight fired
bricks and, furthermore, that recycling cigarette butts in bricks is a very practical and potentially significant contribution
in terms of a sustainable solution to one of the serious environmental pollution problems in the world. |
