Water discharges

with the pre-existing shuttle bus to and from Lomazzo station.
Carpooling has also been organised by employees who share similar journeys to and from work.
A shuttle bus has been made available for the Creomoda and Textrom sites.
Water consumption
With regard to water consumption, the Ratti Group is launching a process which reduces water consumption during the phases of the production process. This will start with the Guanzate plant, which uses 97.78% of the Group’s water resources. In total, 99.08% of the water consumed
by the Ratti Group is drawn from a dedicated
well (with only 0.92% of water consumption coming from the aqueduct) exclusively for the use of the Guanzate plant.
For a number of years the Group has regularly verified water consumption by using a range
of meters. This measurement network currently consists of meters that must be read manually. With regard to the Guanzate premises, monitoring the parameters for water consumption follows the procedure “Surveillance, Monitoring and Measurement”.
In 2018 water consumption saw an increase of 11.90% in light of the 11.70% increase in metres of fabric produced. As a result, the consumption of water per metre of fabric produced remained essentially unchanged (+0.18%).
Compared with 2013, the year in which major investments in washing machinery began, in 2018 consumption per metre was down by 27%.
Water discharges into the sewage network increased by 15.03% in 2018, although in relation to metres of fabric produced the increase recorded was 2.98%.

*For the Tunisia premises water consumption and discharges are not accounted for. Water is drawn from a well.
In order to reduce future water consumption, in 2018 Ratti SpA carried out the following interventions:
• it took an obsolete fume reduction system out of service, which will guarantee a future saving in water consumption estimated at 8,000 m3;
• it replaced a machine used to wash screens and doctor (squeegee) blades in traditional printing. The new machines will guarantee a water saving of 40% thanks to the use of a water recycling methodology.
Careful management of discharges
As far as water discharges are concerned,
at the Guanzate plant the water resulting from production carried out at the plant, including
that from the bathroom facilities, is channelled through the internal collection network
to the primary lifting station, where it is filtered
in a number phases (through bar screens) and pumped into the accumulation basin of the system. In the homogenisation tank there is a redox sensor which, on the basis of pre-set thresholds, actions
a sodium hypochlorite dosing pump which releases the required amount of reagent into the tank. Water collected in this manner is sent to Lura Ambiente SpA of Caronno Pertusella
for purification, as authorised by Autorizzazione Unica Ambientale (single environmental authorisation).
For managing wastewater, in 2018 Ratti SpA created an intermediate storage system for water coming from the scouring bath (with a high
In Tunisia,
Ratti opened a drinking water source outside the Creomoda plant, for the use of the whole of the surrounding community.
