The use of sewage sludge and marble residues in the manufacture of ceramic tile bodies

Valorization of pellets from municipal WWTP sludge in lightweight clay ceramics

“…It can be used in agriculture as a fertilizer or for soil remediation (Kruse and Barrett, 1985), in the cement industry (Tay et al, 2000), as a combustible material (Lee and Bae, 2009) and, to a lesser extent, as a raw material for clay bricks manufacturing (Alleman and Berman, 1984;Weng et al, 2003;Liew et al, 2004;Kaosol, 2010;Latosiń ska and _ Zygadło, 2009;Montero et al, 2009). These alternatives are at the higher level of the pollution-prevention hierarchy, from prevention and reduction (the most preferable option), to recycling and reuse, treatment, and disposal (the least preferable option).…”

Preparation of ultra-lightweight sludge ceramics (ULSC) and application for pharmaceutical advanced wastewater treatment in a biological aerobic filter (BAF)

“…Sludge was used as a kind of addition in ceramics production, which meant that the usage of clay was reduced and sludge was treated, meanwhile wastes can be turned into valuable substances (Montero et al, 2009).…”

Introduction of reversible crosslinker into artificial marbles toward chemical recyclability

“…In addition, a great amount of industrial wastes are normally generated during the processing and manufacturing the artificial marbles such as cutting, grinding and polishing. Therefore, recycling these marble waste has been of particular interest in recent year [12,13]. The artificial marbles such as PMMA resin are basically thermoset polymer composite, and thus their recycling pathway is generally depended on pyrolysis to obtain several organic molecules which is inefficient and time consuming [14][15][16][17].…”
