Landfilling is a practice of disposing of waste by burying it in the ground. However, the term "landfilling" is a bit technical, and many people may be more familiar with its synonyms. For instance, "dumping" is an informal synonym that is commonly used in everyday language. Other synonyms include "burying," "entombing," "disposing," "interment," and "sepulture." Each of these conveys the same idea of disposing of waste by burying it in a designated area. However, the term "landfilling" is still widely used, particularly in official documents and regulations related to waste management.
