UnitedHealth Group’s green business practices in its day-to-day work are reducing the company's impact on the environment in various ways across the enterprise. For example, our OptumRx business is the first major pharmacy care services company to introduce fully sustainable medication packaging that replaces polystyrene, or foam. Safeguarding medications during home delivery is vital. Many medications, including specialty prescriptions, must be kept within strict temperature ranges to arrive safely and undamaged at their destinations. The new OptumRx packaging is made from 100 percent renewable cotton and is biodegradable, compostable, reusable and recyclable, while also ensuring the safety and quality of medications remain intact.
