Waste products are materials that are no longer useful and are discarded. They can come from various sources, including households, industries, and agriculture. Common examples include food scraps, packaging materials, and chemicals. Proper management of waste products is essential to prevent pollution and protect the environment. There are different types of waste products, such as solid waste, liquid waste, and hazardous waste. Solid waste includes items like plastic bottles and paper, while liquid waste can be wastewater from homes or factories. Hazardous waste, which may contain toxic substances, requires special handling to ensure safety and minimize environmental impact.
