Solid waste represents a worldwide concern when regarding its correct destination and its generation. In the industrial sphere, in addition to demanding greater attention due to the possible hazardousness of these wastes, their correct allocation represents high costs for the responsible companies. As an alternative to soften the problem of solid waste disposal is the application of these in building materials and also in agriculture as fertilizers. Such alternatives are related with the concept of Circular Economy, since the use of these in the civil construction or agriculture sectors would reduce the consumption of raw materials in these sectors. Among the solid industrial wastes with notable research attention is the residual sludge from Wastewater Treatment Plants, where it is often sought to find more sustainable alternatives for their correct disposal. In this sense, the present study had as the main objective to analyze the residual sludge from the Wastewater Treatment Plant of a chemical industry and, using its toxicological classification and the characteristics of the Wastewater Treatment Plant and also the industry, and to propose the best alternatives for the sludge destination. This feasibility study was carried out for the application in ceramic, cement and soil culture materials and used many researches already developed in this area, taking into account the treatment required for the sludge in each of the three methods studied and the results presented after disposal of the waste as well as the quality of the material or fertilizer produced. Finally, the sequence of attractiveness found for the application of the sludge in the studied methods was first the application in ceramic materials, then the application in cultivable soils and finally as cementitious materials, however, a more accurate evaluation on the ...( Complete abstract click electronic access below)
