Experimental Study of Cigarette Butt Brick

Several trillion cigarettes are produced worldwide annually, resulting in tonnes of cigarette butt waste. Billions of cigarette butts (CBs) were discarded by smokers directly into the environment. It is known that CBs are one of the environmental pollution. Cigarette butts accumulate in the environment due to the poor biodegradability of the cellulose acetate filters that could cause contamination on the street, sidewalks, waterways, beaches and public areas. Due to its small size but large in volume, CBs cannot be collected easily and most of it will be disposed directly to the landfill. Moreover, there is no easy mechanism to ensure the separation of the chemicals trap inside the CBs which is toxic to the environment Results from a study on recycling cigarette butts into fired clay bricks are presented. In this study, different percentages of CBs (0%, 2.5% and 5.0%) were incorporated into fired clay brick.
