Industrial waste. Industrial waste consists of various types of waste depending on which industry the waste is being generated like power and chemical waste, tubes and tires, chemicals, dyes, paints, etc. Different types of batteries, equipment, food waste, etc.

With the increase in population and industrialization, water resources get polluted by domestic waste and industrial waste. Industrial waste contains organic pollutants, which pollute the environment and are a major cause of concern. Photocatalytic degradation of organic pollutant is the best way to solve this problem because of its simple operation and relatively low cost. Water is a basic necessity of human beings to fulfill a daily requirement, so to purify the water, many attempts have been made, such as porous clay composite, and it is useful in filtration of synthetic pollutants at the lab scale but not at the commercial scale due to its small permeability [96–98]. Aji et al. synthesized C-dots from discarded used oil via the hydrothermal method at the temperature of 120°C, and C-dots can be used as a co-catalyst/photocatalyst for a water purification system. The density of C-dots is a bit lower compared to water, so they float on the water surface and directly receive solar energy, which enhances their potential to be used as a photocatalyst for the purification of water [96]. Prasannan et al. synthesized the composites of ZnO- and N2-doped C-dots using the hydrothermal route with orange peel and used them as a photocatalyst for the degradation of organic dyes [99]. Yang et al. reported the synthesis of nitrogen-doped C-dots via hydrothermal protocol using yeast, which was used as a photocatalyst for the evolution of hydrogen from water under UV irradiation. Thus, nitrogen-doped C-dots as a photocatalyst should be used on a large scale in the area of energy and water cleaning [25].

Industrial waste, consisting of discarded materials during a manufacturing process of factories, industries, and mills, is the waste produced by industrial activity. Pollutants from unmanaged industrial wastes can damage the environment, and methane, which is released from rubbish dumps, also contributes to global climate change. It is estimated that the BOD5 (5-day biochemical oxygen demand) of raw wastes from all industries is more than three times that of all urban sewers (Ghosh et al. 1985).

The generation and landfilling of industrial by-products represent several environmental issues, which has become a worldwide concern in the recent decades. The accumulation of very large amounts of industrial waste in nature often has a negative impact on the environment. They can, pollute the groundwater, air, soil, and vegetation (flora and fauna). Wastes from the industrial and urban activities, constitutes a serious problem and a major challenge for society due to their continued accumulation. Among these waste-producing activities, the thermal power plants are globally criticized for generating large quantities of solid wastes often with a potential environmental impact. As a matter of fact, when the coal is combusted, about 10% of the ash is generated, and the efficient use of large quantities of the coal ash becomes a problem (Sheng et al., 2000). The foremost ecological issues of coal/fly/bottom ash impoundments are the physical and aesthetic alterations on the surrounding environment, as well as the enormous footprints of the mining sites left behind. Furthermore, those wastes have a contentious enduring resilience and might require pricey management procedures.
Strength and durability studies on sustainable eco-friendly green solid blocks
Published in International Journal of Coal Preparation and Utilization, 2022
Industrial waste disposal has become a worldwide issue due to landfill space constraints, dangers to ecological systems, and related risks to human health. An attempt was made to develop eco-friendly, sustainably assembled Solid Blocks by varying the proportions of ingredients with a composition of fly ash, coal ash, lime, granite powder, and olivine sand. The primary objective of this study is to use waste materials in the production of building blocks while maintaining the strength and durability parameters. One of the main ingredients in ordinary Conventional Fly Ash Blocks is cement. However, cement was not used in this study. We could significantly reduce CO2 emissions by reducing the consumption of cement in Solid Block production.

Every day, industries produce tons of waste containing compounds that have negative effects on land, water bodies, besides atmosphere. Dirt, gravel, scrap metal, oil, solvents, chemicals, and even restaurant waste are examples of industrial waste. Factories and power plants are generally located near water bodies, and fresh water is used for manufacturing and cooling purposes. Many industries lack the resources to properly dispose of or recycle waste. Sewage discharged into water bodies has an impact on marine ecosystem as well as on life that depends on it. The toxic effects of waste water can destroy marine life and has a variety of effects on species.[1] Different coloring substances with various chemical properties are dumped into water bodies. Dye removal has been a significant issue in recent decades.[2] Dying and printing processes are common sources of wastewater containing dyes in it. These dyes are used to color the final products of industry, such as fabric, paper etc. Majority of dyes used in textile industry are of synthetic nature.[3,4] Dyes are accountable for allergic reactions, dermatitis, skin irritation, and even cancer.[5,6]
