Development of Bricks and Concrete by Utilizing Waste from Toothpaste Industry

Abstract

Due to the rising amount of sludge produced by industrial plants, there is a strong demand for environmentally friendly reuse and efficient disposal methods for sludge. The aim of this study was to investigate the effects of using Toothpaste Industry Waste (TPIS) on the compressive strength of concrete and bricks in order to determine the best substitution percentage for waste utilisation. Due to high treatment costs and risks to the environment and human health, sludge is a serious concern. It is also becoming a more difficult issue due to the lack of suitable disposal sites. The waste management issue at TPIS will be solved as a result of this study. Rapid industrialization has resulted in the production of vast amounts of waste, and there is still slackness in the process of efficiently using it. It is causing environmental and ecological problems in addition to occupying vast swaths of productive cultivable land, which is in short supply in India. Some of these wastes have been found to have a lot of potential and can be used as a raw material or a blending component. The reuse of industrial wastes will not only help to solve the environmental pollution issues associated with their disposal, but it will also aid in the preservation and restoration of natural resources that are rapidly depleting. Because of its chemical composition, sludge produced by industries such as toothpaste manufacturing units (TPIS) contains a significant amount of calcium carbonate (CaCO3), which is prohibited from being discharged openly. The created sludge is stored in gunny bags in open or closed basins. Currently, toothpaste waste is disposed of by spreading it on soil, covering it with dirt, or transporting it to a cement plant for incineration. Because of land constraints and long distance transportation, both methods of disposal may not be suitable.
