Definition
waste management
Landfilling is the process of burying waste materials in large depressions in the ground, known as landfills. This method is commonly used for the disposal of municipal solid waste. The process involves the careful layering and compacting of waste, which is then covered with soil to minimize odors and pests. Environmental regulations govern how landfilling should be conducted to prevent contamination of soil and groundwater. Over time, landfills can become sites for energy recovery and can be monitored for environmental impact.
Synonyms
dumping, refuse burying, waste disposal.
Examples of usage
- The city is considering new landfilling regulations.
- Landfilling is often the cheapest waste disposal method.
- Proper landfilling techniques reduce environmental risks.

Interesting Facts
Environmental Impact
- Landfilling can produce methane gas, a potent greenhouse gas that contributes to climate change.
- Properly managed landfills can capture gases and turn them into energy, reducing waste and pollution.
- If not monitored, toxic substances from landfills can seep into the ground and water, harming the environment.
History
- In ancient times, cities disposed of waste in pits; modern landfilling began in the 20th century.
- The first engineered landfill was established in California in 1937, focusing on environmental safety.
- Landfilling was preferred over open dumping due to increased urbanization and stricter waste regulations.
Science
- Landfills are typically layered with clay and plastic to minimize leakage of harmful substances.
- As waste decomposes in a landfill, it can take years or decades to break down, depending on the materials.
- Microorganisms play a crucial role in breaking down organic waste, highlighting the complex ecosystem within landfills.
Social Considerations
- Communities often oppose new landfills due to fears of pollution and decreased property values.
- Public perception of landfilling can vary widely, with some seeing it as a necessary disposal method and others advocating for alternatives like recycling.
- Landfills sometimes become sites for community initiatives, such as solar farms, once they are closed.
Regulations
- Many countries have established strict laws governing the design and operation of landfills to protect public health.
- The Resource Conservation and Recovery Act in the U.S. regulates waste management practices, including landfilling.
- In some regions, landfilling is seen as a last resort, with a focus on reducing waste through composting and recycling before disposal.
Origin of 'landfilling'
The term 'landfilling' is derived from the combination of the words 'land' and 'fill,' indicating the act of filling land with waste material. Its usage became prevalent in the mid-20th century as cities grew and industrial waste increased significantly. The concept of landfilling as a waste management practice was established due to the limitations of open dumping, which posed serious environmental hazards. Landfills were initially dug in areas deemed less valuable, but as urban development expanded, the need for more regulated landfills became apparent. Modern landfilling methods have evolved to include liner systems and leachate collection to mitigate environmental impact, reflecting ongoing advancements in waste management practices.
