Owner Vetropack, Trezzano sul Naviglio
Restorarion Drytech Italia, Como
WATER TOWER, TREZZANO S/N / Drytech carried out the restoration work on the Vetropack plant water tower in Corsico with injections of waterproofing resin from the outside, without having to empty the water tank.
The fire-fighting water reserve was thus guaranteed for the continuous-cycle industrial systems even during the renovation work and the company didn’t have to hire a tanker truck for the fire brigade. Unlike traditional restoration work carried out from inside the tank, the Drytech system not only avoids emptying the tanks, but it is also no longer necessary to descend into the tanks, with all the related logistical and safety implications.
In order to carry out the work at the Milan plant, Drytech technicians used scaffolding already set up by another company to restore the external surface of the tower, on which the wear of time and the elements had produced the first surfacing of the metal reinforcement.
Normally, however, the Drytech Restoration System allows and includes the use of practical aerial platforms, with a consequent saving on costs and the time required for setting up scaffolding. Being able to carry out restoration work and avoid reductions or stops in production is an important issue for a group which produces 4.5 billion glass containers a year, with 3,000 employees in 7 countries, and plants working 24 hours a day.
Vetropack, one of the main European producers, had already started to recycle used glass in Switzerland in the 1970s and had adopted responsible management of raw materials and environmental sustainability of the key elements of its activities. So much so, that today the share of recycled glass to produce new containers in some of the Group's plants reaches 85%. Production of glass using recycled material requires less energy and natural resources than production using primary raw materials such as sand, lime and soda ash.
Moreover, there are specific processes which make the glass lighter, with the same quality.
The lightweight version of a 0.75-litre wine bottle weighs only 350 grams instead of 400, while a small beer bottle weighs only 160 grams, compared to 190 grams for the traditional one. A weight reduction means fewer raw materials, lower energy and material consumption, lower transport costs and reduced CO2 emissions.
