Environmental Sustainability

CONSERVATION: Each of ON Semiconductor’s factories is engaged in multiple sustainability projects aimed at conserving water, electricity and fuel. Our worldwide manufacturing operations have well-established recycling and waste minimization programs in place. Ongoing programs include reusing rinse water in our fabs, reducing water flow during equipment idle periods, reducing electricity use, reducing chemical use via process optimization, recovering heat from boilers, balancing our air streams.

RECLAIM / RECYCLE: During 2011, more than 1,600 metric tons of scrap materials and 1,400 pounds of precious metals from the company’s worldwide manufacturing facilities were processed, sorted, and sold for reuse. The reclamation of these materials recouped more than $36 million in 2011 alone.

NETWORK OPTIMIZATION: The company’s logistics team - responsible for shipment and delivery of the 42 billion products we annually manufacture and ship - has reduced the in-transit mileage logged by our parts by more than 50 million miles per year – thus reducing the company’s carbon footprint. The company’s right-size packaging program has significantly reduced the amount of corrugated carton materials and polyethylene-base materials being used – a reduction of more than 23 tons annually.

STANDARDS: The vast majority of ON Semiconductor’s product portfolio – consisting of more than 42,000 different devices – have been converted to meet industry RoHS standards. Many products are available in lead-free (Pb-free) packaging. DFN/QFN package families are available in Halogen-free mold compounds and we are qualifying and converting other packages.

PARTNERSHIPS: ON Semiconductor belongs to a number of organizations and initiatives focused on technological advances in sustainable energy, power conservation and corporate responsibility. These include membership in the Electronic Industry Citizenship Coalition's (EICC) including their Environmental Sustainability and Conflict Minerals groups; the Semiconductor Research Corp’s (SRC) global Energy Research Initiative (ERI); Europe’s Energy for a Green Society ENIAC JU project, and membership in Power Sources Manufacturers Association (PSMA) and the China Power Supply Society.

ON Semiconductor is dedicated to annually reducing our energy consumption by 5 percent, our water consumption by 5 percent and our overall carbon footprint by 5 percent.
