• A cascade water recycling system could be installed to reduce the water and energy consumption in bottling. The system in place did not re-use any water. For each of the four separate washing steps, freshwater had to be taken from the tap, heated up by steam or electric energy, and discharged to wastewater treatment. A cascade system would use freshwater only for the final washing step and re-use the lightly polluted wastewater of this step as water input to the second-last washing step, the wastewater from that step as input for the third- last step, and so on, thereby enabling freshwater, wastewater, and the steam demand to heat water to be reduced
