What is the most common method of solid waste disposal?

Landfilling is the most common method of solid waste disposal primarily due to its capacity to handle large volumes of waste efficiently. Landfills are designed to contain waste safely while minimizing environmental impacts, often equipped with liners and leachate collection systems to prevent contamination of groundwater. This method allows for the disposal of various types of solid waste, including household, industrial, and construction debris.

In many regions, landfilling is favored because it is relatively cost-effective and provides a straightforward solution for managing waste. While incineration can reduce waste volume and release energy, it may involve higher operational costs and concerns regarding air pollution. Recycling and composting play important roles in waste management by reducing the overall amount of waste sent to landfills, but these methods typically account for a smaller proportion of total waste disposal compared to landfilling. Thus, while incineration, recycling, and composting are valuable strategies in a holistic waste management plan, landfilling remains the predominant method due to its widespread accessibility and practicality for waste disposal.
