Environmental Health 66 2021 Sustainability Report A Modern, High-Performing Health System Introduction Our People and Culture Responsible Business Practices Performance Data We are dedicated to finding innovative ways to manage waste through prevention, reuse, recycling and disposal. Diverting waste from landfills Our multidimensional approach to minimizing our environmental impact includes ongoing management of our various waste streams, including municipal, construction, electronic, hazardous and regulated medical and pharmaceutical waste. With our scope 3 enterprisewide waste-associated carbon emissions inventory underway in 2022, our focus on waste reduction remains an important part of our sustainability strategy. Additionally, we are considering an enterprise diversion rate goal for 2023, to be informed by our ongoing comprehensive inventory assessment and several pilots. • In the Asia-P acific region, we removed all single-use plastic and paper products in 2021, preventing over 68,000 pounds of waste in a landfill annually. • Our Optum T echnology team manages a successful electronic waste recycle/reuse program that avoided 600,000 kilograms of waste in 2021 by repurposing or recycling electronics, including over 100,000 notebooks and PCs. In 2022, we plan to implement new solutions to improve efficiency and reduce waste, including: • Incr easing the medication pack sizes carried by Optum Rx home delivery pharmacies, which could lead to the disposal of 546,000 fewer plastic bottles and caps per year. • Piloting the use of insulated mailer s to ship medications that require refrigeration, which could eliminate an estimated 1 million gel packs per year. • Piloting a r eusable, closed-loop medication cooler for pharmacy deliveries that measures the temperature and location of the package, allowing for retrieval and reuse of coolers multiple times per month and reducing the number of reshipments.
