Industrial residues, e.g. from mineral processing, metallurgy, ceramics, energy production and waste treatment, contain synthetic analogues of natural mineral phases, whose physical and chemical properties determine their application as secondary raw material as anthropogenic ore or construction material and also their behaviour in landfills.
The dominant compositions were SiO2, Al2O3, CaO, Fe2O3, Na2O, and ZnO. The results indicated that all the industrial wastes RM, FS, and RC could be used for floor tile production. The new products, composed in wt of 70RM, 15FS, and 15RC and fired at 1050 o C, fulfilled the requirements of the Thailand industrial standard 2398-2551.
Nov 26, 2011 The investigation of suitable alternative sources of energy is currently an important challenge for Brazilian researchers. In this study, the use of biomass residues in ceramic furnaces was investigated with the aim of obtaining a total or partial replacement of existing non-legalized biofuels, mainly from deforestation sources. For that purpose, the agricultural production of the region and ...

Jan 02, 2018 Agricultural residues are rich in bioactive compounds. These residues can be used as an alternate source for the production of different products like biogas, biofuel, mushroom, and tempeh as the raw material in various researches and industries. The use of agro-industrial wastes as raw materials can help to reduce the production cost and also reduce the pollution load from the environment.
May 01, 2016 Electrolytic manganese residues EMR are one of industrial byproducts generated during the production of electrolytic manganese metal. To reduce the EMR hazard to environment and invent valueadded materials, porous ceramics were prepared by the poreforming method with EMR and various additives. The influences of the incorporation of different additives, sintering temperature,
The reuse of production residues generated in ceramic production facilities and in external processes may occur according to various organisational schemes depending on the equipment present at the sites and the nature of the material. At a sectoral level, the average waste reuse factor stands at a value of 129, well above the value of 50 ...
11.7 Ceramic Products Manufacturing 11.7.1 General1-3 Ceramics are defined as a class of inorganic, nonmetallic solids that are subjected to high temperature in manufacture andor use. The most common ceramics are composed of oxides, carbides, and nitrides. Silicides, borides, phosphides, tellurides, and selenides also are used to produce ceramics.
