WASTE MANAGEMENT AND RECYCLING Across all our operations in 2021, we recycled 184,000 metric tons of materials, bringing us to more than 1 million metric tons recycled companywide since 2014. That total includes more than 220,000 pounds of recycled electronic waste, refinery process catalyst captured for metals reclamation, oils and solids captured for reuse, and recyclable materials such as metal, glass and paper. We also achieved a 20% reduction in power usage at company-operated data centers. We track every raw material used in the manufacturing process at our lubricants plants. In 2021, we recycled 950 tons of scrap material across our portfolio, including cardboard, bottles, cans, pallets and shrink wrap. Tanks at our refineries and terminals require periodic cleanouts, and we must dispose of the residual product in compliance with strict environmental laws. Phillips 66 has a systematic hazardous waste program with processes and practices executed by trained personnel. Each of our operating sites has environmental professionals whose expertise is supplemented by corporate staff. In 2021, our tank cleanout methods led to the generation of 1.7 million gallons of waste-derived fuel for manufacturing processes and conserved more than 170,000 gallons of water. Obsolete electronic equipment is sustainably processed through a third-party provider. When possible, the equipment is refurbished and used for other purposes. Other times, it's broken down into useable component materials. We recycled or refurbished 223,724 pounds of Information Technology (IT) equipment across our U.S. facilities in 2021. Arrows of Impact Our Arrows of Impact program is designed to reduce waste at our Houston Headquarters by 20% by the fourth quarter of 2022. Launched on America Recycles Day in 2021, the program makes recycling more convenient and educates employees on what and how to recycle. In 2021, we generated about 200 pounds of waste per person at our Houston Headquarters, and through our program, we recycled 26 metric tons and composted 0.55 metric tons of café waste, coffee grounds and napkins. Our recycling efforts: • Conserved 172,848 gallons of water and 36,632 kilowatt-hours of electricity • Saved 468 mature trees • Prevented 7 metric tons of CO 2 e GHG emissions But we can still do better. That's why we implemented the following initiatives to achieve our Arrows of Impact goal: • Adding reusable containers in the cafeteria: Each reusable container can be used 1,000 times. Using 500 reusable containers will replace 50 months’ worth of disposable containers • Increasing composting from the café • Reducing the use of disposable cups • Installing hand dryers in our restrooms 20% reduction in power use at company-operated data centers 184,000 metric tons of materials recycled in 2021 34 PHILLIPS 66 2022 SUSTAINABILITY REPORT OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT
