Industrial Waste

Industrial activities boost the economy but generate significant solid waste, which can be biodegradable or non-biodegradable. Biodegradable waste includes materials from food-processing units and can decompose naturally. Non-biodegradable waste, such as fly ash and slag, requires careful disposal due to its potential environmental impact. Hazardous wastes from industries pose additional risks due to their reactive nature. Proper disposal methods, including controlled incineration, are crucial to mitigate environmental threats. Some waste by-products are repurposed, like using fly ash in cement production.
