Abstract
Las colillas de cigarrillo son uno de los residuos mas comunes a nivel mundial. Sus componentes toxicos y no biodegradables hacen de este un residuo peligroso y una de las causas de contaminacion ambiental. Este articulo presenta los resultados de una investigacion en la que se estudio la alternativa de incorporar colillas de cigarrillo en la fabricacion de ladrillos de arcilla. Se elaboraron cuatro mezclas dentro de las que se incluye una mezcla patron con contenido de 100% arcilla (LADRICOL 0%) y tres adicionales con colillas de cigarrillo en diferentes porcentajes en peso (LADRICOL 2,5%, LADRICOL 5% y LADRICOL 7,5%). Estas mezclas fueron cocidas a diferentes temperaturas y se sometieron a los ensayos respectivos para determinar propiedades fisicas y mecanicas del producto terminado. Los resultados obtenidos, demostraron que, con la adicion de colillas de cigarrillo en un 2,5% y una temperatura optima de coccion de 850°C, se pueden fabricar ladrillos no estructurales tipo M, cumpliendo con los estandares establecidos en la NTC 4205-2, generando impactos positivos en el medio ambiente y reduciendo el consumo energetico durante la coccion del ladrillo, en un 19,75% .

Cigarette butts are undoubtedly the most common type of waste dumped on the streets
The materials used to make cigarette filters include cellulose acetate, a non-biodegradable material that can take between eighteen months and ten years to decompose depending on the environmental conditions to which it is exposed
This article presents the results of an investigation where cigarette butts were recycled by including them in the manufacture of clay bricks, evaluating the effect of the firing temperature on the physical and mechanical properties of the bricks, as well as its effect on the possible reduction of energy costs associated with their manufacture
Summary
Cigarette butts are undoubtedly the most common type of waste dumped on the streets. The high rates of waste dumped into the soil and water sources without control have become one of the causes of pollution, by the high volume of cigarette butts dumped and by the toxic substances present in these products. The materials used to make cigarette filters include cellulose acetate, a non-biodegradable material that can take between eighteen months and ten years to decompose depending on the environmental conditions to which it is exposed. The sun rays can break the filter down into small pieces, this material never disappears; instead, it passes into the soil and water sources, causing environmental pollution (Novotny and Slaughter, 2014) and (Mohajerani et al, 2016). One cigarette can contaminate up to 50 liters of water (Guevara, 2010) and (Lozano et al, 2015)
