Reducing water consumption

TECHNOLOGICAL INNOVATION TO REDUCE WATER CONSUMPTION IN CARMIGNANO

Gurit’s Carmignano Site is working to reduce its water consumption and water pollution. One of the initiatives involves the PET recycling process as detailed below.

To extrude the molten plastic into fine strands, the vacuum pumps of the extruder use water. At the end of the process, the water, which has interacted with contaminated air, needs to be treated as hazardous waste. These vacuum pumps are being replaced by new ones which won’t require water consumption to work and therefore won’t produce polluted water.

The new vacuum pumps will save 208 000 litres of water per year (4 000 litres per week) and reduce hazardous waste by the same amount.
