Waste

Waste refers to materials that are undesired or cannot be utilized. It encompasses any substance that is discarded following its initial use, being deemed as either worthless, defective, or lacking in utility. In contrast, a by-product is a co-produced item with relatively limited economic value. Through innovation, a waste product has the potential to transform into a by-product, joint product, or even a resource by increasing its value beyond zero.

Types of Waste

• Solid Waste: Solid waste encompasses a wide range of materials, such as household garbage, industrial waste, and construction debris. Proper disposal and recycling of solid waste are essential to prevent environmental pollution and conserve resources.
• Liquid Waste: Liquid waste includes wastewater from households, industries, and agricultural activities. Improper disposal of liquid waste can contaminate water sources, leading to serious environmental and health issues. Wastewater treatment is a critical process to remove pollutants and ensure safe water discharge.
• Gaseous Waste: Gaseous waste involves the release of harmful gases into the atmosphere, often as a result of industrial processes or combustion. Air pollution from gaseous waste can have detrimental effects on air quality and contribute to climate change.
