Question
What are the common processes of waste disposal?
Answer
The common processes of waste disposal include:
- Landfilling: It involves burying the waste in the ground, usually in a specially engineered site, to prevent the contamination of soil and groundwater.
- Incineration: It involves burning the waste in high-temperature furnaces, which can generate heat and electricity. However, incineration produces air pollution and can also release toxic byproducts.
- Recycling: It involves collecting, sorting, and processing waste materials to make new products, reducing the need for virgin materials and conserving natural resources.
- Composting: It involves the natural decomposition of organic waste, such as food and yard waste, into nutrient-rich soil that can be used for gardening and farming.
