This work aimed to propose alternatives to minimize environmental impacts caused by the generation of solid and liquid waste from the truck wash in a concrete industry in the municipality of Santa Maria - RS. For the analysis of wastewater samples were collected from June to October 2009, in five pre-defined points. The values obtained by the analysis were compared with the results of the control sample and the values determined by NBR 13.696 (ABNT, 1997). The evaluation of theses parameters showed the actual efficiency of decanters already installer in the Company. With this, was found the need to design a new system. The residue (sludge) from the decanters already deployed in the enterprise was removed with a shovel, and air dried in a moist chamber incorporated in the mortar and sieved by replacing the sand by percentages of 10%, 25% and 50%. The bodies of the specimens were broken at 7, 14 and 28 days of healing. The effluent showed a large disparity between the control sample (borehole) and the end of the sample treatment system. Regarding solid waste, incorporate the sludge generated in the industry can mean the reduction of environmental impact, thereby contributing to sustainable development, where there will be no wasted material generated.
