If you accidentally take the soy milk glass bottle away, you can try to return it to the restaurant or merchant. You can explain the situation to them and apologize. If the merchant doesn't need the bottle, you can throw it away or recycle it to the appropriate trash can or recycling bin.

Please note that some regions may have specific regulations on garbage sorting and recycling. Please ensure that you handle glass bottles according to local regulations. If you are not sure how to deal with it, you can consult the local environmental protection organization, garbage collection station or local government.
