What is a fancy name for garbage?

There are many fancy, professional, and euphemistic names for garbage that are used in waste management, environmental science, and polite conversation to make the term sound more respectable or technical. The most common professional term is solid waste, which is the official term used by the Environmental Protection Agency and municipalities. Other fancy and technical terms include municipal solid waste or MSW for household trash, refuse, which is the classic formal term used in Britain and in US sanitation departments, discards, residuals, and post-consumer materials. In environmental and sustainability circles, you will hear resource recovery materials, recyclable feedstock, or diverted materials to emphasize that garbage can be reused. For household contexts, people use euphemisms like household waste, domestic refuse, or unwanted materials. In commercial settings, terms like commercial waste, industrial byproducts, and debris are used. British English often uses rubbish as a slightly more polite term, while in formal writing you might see detritus, effluvia, or offal for specific types of waste. Waste management companies have popularized terms like sanitation materials and environmental waste to professionalize the industry. If you want to sound particularly fancy at a dinner party, you could refer to garbage as superfluous household artifacts or obsolete material possessions.
