Waste disposal refers to the process of collecting, transporting, and disposing of waste materials in a safe and environmentally friendly manner. This includes various types of waste, such as household waste, industrial waste, and hazardous materials. Proper waste disposal helps prevent pollution and protects public health. There are several methods of waste disposal, including landfilling, incineration, and recycling. Landfilling involves burying waste in designated areas, while incineration burns waste to reduce its volume. Recycling reprocesses materials to create new products, conserving resources and reducing the amount of waste sent to landfills.
