The die casting process has important interactions with the environment. The considerable amount of heat energy necessary for melting the metal, are formed by the combustion of methane.
The aluminium die-casting process involves important interactions with the environment. The considerable amounts of thermal energy needed to melt the metal are obtained by methane combustion. The motive energy, indispensable for moving the presses that give the metal its shape, is released by powerful electrically-operated hydraulic motors. All the machinery for the subsequent aluminium machining processes also work through electrical energy. The company's objective is to achieve by 2016 a 300 kWp photovoltaic plant.
Water, too, is an indispensable part of the process as, running in the cooling ducts, it prevents overheating of the machine.
The natural element mostly in contact with production is without doubt the air.

Fully aware of these impacts on the environment, PRESSO FONDERIE has always endeavoured to adopt the best technologies available on the market to reduce these impacts. Regard to interactions with the air, PRESSO FONDERIE from 2015 can boast 2 moderns and efficients purification plants for the vapours leading from the  urnaces and presses. These vapours are drawn into sealed ducts and conveyed through a vertical filter in two  filters. After this process the purified air is released through two chimneys at a height of 15 metres from the ground, which are continuously monitored by appropriately adjusted electronic sensors in the final section that are controlled on a routine basis. Other impacts on the air could be caused by the water recovery system that works through vacuum evaporation at low temperature.


In the event of leaks, the CFC or HCFC gases used in the cooling circuit could cause damage to the ozone layer in the atmosphere. In this case, too, PRESSO FONDERIE behaves in an ethical manner, because every year specialised personnel check the tightness of the cooling circuit using an electronic meter calibrated especially.


From September 2016 the photofoltaic system startup will lead to a reduction of emission of substances polluting effect and those that have a contribute to the greenhouse effect

We estimate that we will reduce our emission of:

CO2 carbon dioxide 188.591,84 kg in one year - 3.466.112.03 in twenty years

SO2 sulfu dioxide 353,61 kg in one year - 6.498,95 in twenty years

NOX nitrogen oxiden 220,53 kg in one year - 4.053,11 in twenty years
