Experimental Studies on Disposal of Various Industrial Solid Wastes

Abstract

In the present study, solid waste from various industries has been collected and characterized. Based on the nature and composition of solid waste, the possible chemical composition is evaluated and value added products are prepared. Methods for conversion of solid wastes into building materials such as bricks and concrete blocks have been described. Mixing of solid waste in various proportions with red soil also carried out as pot experiment. From the results of various tests on final product, it is concluded that solid waste can be used suitably to produce bricks with 25-30% of sludge, for concrete blocks with 45-50% of sludge. By applying this type of alternative, solid waste could be disposed off in a better way without affecting the existing environment.

Utilization of sludge in manufacturing Energy Efficient Bricks

“…Waste lime sludge [7], Petroleum plant sludge [8] also can be used as building material. Solid waste from textile mill has the potential for use as additive in building material [1,9]. Balasubramanian [10] used up to 30% textile mill sludge in brick making with satisfactory compressive strength.…”

Adsorption of Chromium Ions from Aqueous Solutions by Synthesized Nanoparticles

“…Heavy metals may defined as metal with a density greater than 4 gm/cm 3 or metals with a high atomic weight or metals commonly used in industry and toxic to man and other organisms. These include arsenic (As), silver (Ag), chromium (Cr), mercury (Hg), and platinum group of metal [1].…”

“…These include arsenic (As), silver (Ag), chromium (Cr), mercury (Hg), and platinum group of metal [1]. The various anthropogenic activities that introduce the heavy metals in the environment are mining of ores, municipal waste, burning, and agricultural activities [2,3]. The released toxic metals are having more dangerous to concentrate in ecosystems and habitats.…”
