Sanitary Landfilling
- Sanitary landfilling, also known as controlled tipping, is a method of waste disposal where refuse is systematically deposited in a landfill area designed to minimize environmental impact.
- This method involves placing waste in a controlled manner, compacting it, and covering it with soil to prevent exposure to the environment and reduce odors and pests.
- Sanitary landfilling is divided into smaller portions called cells, each of which is filled, compacted, and covered daily or regularly.
Evaluating the Statements
Statement 1: Another name of sanitary landfilling is controlled tipping.
- This statement is correct. Sanitary landfilling is often referred to as controlled tipping.
Statement 2: Waste is stabilized by the aerobic process alone.
- This statement is incorrect. While initial waste decomposition may involve aerobic processes, the majority of waste stabilization in sanitary landfills occurs through anaerobic processes due to the lack of oxygen in deeper layers of the landfill.
Statement 3: Refuse is dumped into a low-lying area.
- This statement is correct. Sanitary landfills are often located in low-lying areas to contain and manage waste more effectively.
Statement 4: In the sanitary landfilling, filling of refuse is actually carried out by dividing the entire landfill area into smaller portions called cells.
- This statement is correct. The landfill area is divided into smaller cells for better management and operational efficiency.
