A method for processing of glass containers includes: simultaneously subjecting the glass containers to a first processing step; and simultaneously subjecting the glass containers to a second processing step after the first processing step. At least one of before or during at least one of the first processing step or the second processing step an outer container surface of each glass container is contact-free or in contact with a material having a lower hardness than that of the glass container or only in contact with such materials.

There is described a washing machine configured to wash empty containers adapted to be filled with a pourable product, the washing machine includes: a conveyor device configured to convey a plurality of containers along a washing path in an advancement direction; at least one tank for holding a cleaning medium, the washing path extending within and along the tank; and a hollow passage which extends through the tank and which is fluidly isolated from the tank. The washing machine further includes a pair of extraction devices arranged in fluid communication with the tank, fluidly isolated from the hollow passage, and configured for detaching/removing labels from the containers advanced in the tank and for receiving the detached/removed labels, thereby extracting such labels from the tank.
