Garbage bags are a household essential, but sometimes we may need to swap out the word "garbage" for something else. In terms of synonyms, one option is "trash bags," which is a more common American usage. "Refuse sacks" is another term used in the UK, while "rubbish bags" is commonly used in Australia and New Zealand. "Waste bags" is a more generic term that can include recycling or composting materials. For more eco-friendly options, "compost bags" or "biodegradable bags" may fit the bill. Whatever term you use, make sure to use it responsibly - reducing the amount of waste in the first place is always the best option.
