Microstructural Evaluation of Clayey Ceramic Incorporated with Sludge from Paper Manufacturing

“…One of these alternatives is the incorporation of the sludge into conventional clay ceramics. For the ceramic industries, the incorporation of this sludge as a waste, in addition to saving raw material and benefiting the environment, could lead to the elaboration of new products with compatible quality with the existing ones in the traditional market [1] In the paper manufacturing industry, after the initial treatment, the decanted solids go through a dewatering process, followed by a drying stage, in which a solid matter, denominated primary sludge, is generated. This sludge resembles a paper paste of dark gray color when humid, and clear gray color when dried and is basically composed of kaolin, pulp, traces of chemical substances and water.…”

Life Cycle Assessment of Renewable Energy Alternatives for Replacement of Natural Gas in Building Material Industry

“…Various studies have been conducted to optimize kilns and plants [5][6][7], to study the effects of additives on fuel consumption and on mechanical-physical properties of bricks [8][9][10], to develop sustainable construction materials via waste recycling [11,12], and to assess life cycle of buildings or building construction systems [13,14]. Notwithstanding, less attention seems to be paid to the evaluation of environmental impact caused by the production of certain types of construction materials, or to rate changes of environmental impact caused by the substitution of fuel.…”
