Driving Sustainability in Semiconductor Manufacturing
STMicroelectronics (STM), a global leader in semiconductor technology, is committed to achieving carbon neutrality by 2027. With over 60,000 m² of cleanroom space across its Agrate, Castelletto, and Catania facilities in Italy, STM has enlisted Deerns for several production extension and decarbonisation projects that support this ambitious goal.
Deerns’ work includes extensions to cleanrooms and new process critical systems (high purity specialty gases and chemicals), including on-site environmental, health, and safety (EHS) construction management. Key upgrades include modernising chiller systems to maintain precise production temperatures and integrating energy recovery solutions to optimise HVAC efficiency in cleanrooms.

From initial design to project execution, validation, quality control and commissioning, the entire process is overseen by Deerns to ensure optimal results. This includes developing a comprehensive risk inventory including mitigation strategies, ensuring compliance, integrating new initiatives with current systems, and monitoring the project post-handover to verify that targets are consistently met.
