Non-returnable glass (the bottles that are packed in boxes):before throwing the bottles away in the correct bin, remember to remove the cap and empty completely the contents. You can leave the label or other accessories that are difficult to remove.
Returnable glass (the bottles that are packed in plastic crates):just replace the bottles in the plastic delivery crates. The glass once sanitized and controlled will be ready for re-use.
Remember NOT to use returnable glass bottles to hold other liquids (oil, alcohol, etc.) especially non food (detergents, petrol, etc.). They may no longer be fit to contain water.
