Okay, the user wants me to translate "litter bin" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it as is. The third rule is to provide only the translation without any explanations.
So, "litter bin" is in English. I need to translate it. The direct translation for "litter bin" in Thai is "ถังขยะ" which is the standard term for a trash can. I should make sure there's no alternative term that's more commonly used. Let me confirm that "ถังขยะ" is correct. Yes, that's right. No need to add anything else. Just output the translation without any explanations.
