A trash dump, also known as a rubbish dump, is a designated area where waste materials are tipped, dumped or disposed of. Other synonyms for trash dump include landfill, garbage heap, trash heap, rubbish tip, waste disposal site, dumping ground, junkyard, and scrapyard. The term landfill is commonly used for a large-scale disposal site that follows ecological guidelines, while garbage heap, junkyard, and scrapyard are often used to describe smaller, unregulated sites where waste materials are haphazardly piled up. Regardless of the terminology used to describe them, these sites are responsible for managing waste materials that would otherwise become environmental hazards and pose serious health risks to the public.
