Brickmakers, in general, use low quality fuels such as sawdust, scrap wood, used motor oil, waste plastics, and scrap tires to fire their bricks. Pollutants produced during the firing process include particulate, organic compounds, carbon monoxide and nitrogen oxides. A new technology was designed to address air pollution from brick kilns. The MK system involves covering the kilns with a dome and channeling the output of an active kiln through a second, identical loaded kiln for its additional filtration of the effluents. Kilns of a pair are connected via clay brick channels. The roles are reversed after the initial kiln is refilled. The objectives presented in this work summarize the efforts placed on the deployment and development of the MK Kiln system in Ciudad Juarez. An environmental impact study was developed using multicriteria, risk cartography, and on site air and soil pollutant analyses. The results of these studies were submitted to local and state officer in order to help with the selection of the best site for the brick kiln relocation. The emissions are reduced with the use of the MK kilns with simultaneous benefits to the brickmakers. However, this project still in process because of political and economical issues and represents a challenging to reduce the pollution derived from 297 traditional brick kilns that exist in Ciudad Juarez.
