Renewable. 56% of electricity powered by wind turbines in ST's Bouskoura site

Energy saving. 4,500 MWh/year saving at ST's Rousset site.

Recycling. 98% of waste reused or recycled at ST's Calamba site.

We mitigate the environmental impact of our manufacturing operations.

Environmental initiatives in our manufacturing sites

We strive to reduce the impact of our manufacturing activities on natural resources by managing our greenhouse gas (GHG) emissions, reducing our energy, water and chemical consumption, and recycling waste.

Fans

Wind farm

Bouskoura (Morocco)

As part of the move towards more renewable energy sourcing, our Bouskoura site benefits from the electricity produced by 12 wind turbines installed in the framework of a power purchase agreement. In 2022, these turbines supplied 56% of the power used by the site, contributing to a reduction in CO2 emissions of about 31,500 metric tons. The site also extended its 4,000 m2 photovoltaic carport. An additional 3,100 m2 of solar panels, installed in 2023, supply approximately 0.9 GWh of electricity.

Zero Waste

Zero waste to landfill

Calamba (Philippines)

ST's waste management strategy is based on reduction, reuse, recycling, elimination, and treatment. Our Calamba site implemented various programs such as 'no disposable Wednesdays', color-coded bins, waste electrical and electronic equipment recycling, and a solid material waste recovery shed. Thanks to these efforts the site successfully passed the zero waste to landfill (ZWTL) certification and achieved a waste reuse and recycling rate for 98% in 2022.

Cooling Systems

Free cooling systems

Rousset (France)

In 2022, ST inaugurated an innovative energy efficiency system with Dalkia at its production site in Rousset. This system uses the outside air to cool the production equipment, thereby reducing the use of refrigeration units during colder weather. The new aero free cooling system and chillers should reduce energy consumption by 20% - up to 4,500 MWh per year - contributing to ST’s commitment to achieve carbon neutrality by 2027. 

Depuration

Phytodepuration program

Kirkop (Malta)

Our Kirkop site launched an original and innovative project to address heavy metals. The site initiated a program with the University of Alessandria (Italy) to study the effectiveness and efficiency of using phytoremediation to treat a drain containing heavy metals from plating. In this process, plants clean the wastewater by absorbing the metals through their roots. If successful, this method can potentially be used at other ST sites.
