Coram CVS Specialty Infusion Services (Coram) has started using a new paper-based packaging format for temperature-sensitive medicines, replacing expanded polystyrene (EPS) or styrofoam.

The company said patients are already receiving medicines in recyclable packaging made primarily from paper.

The change is part of broader sustainability goals and is also intended to support patient care.

According to Coram, the updated packaging had been tested against existing materials and showed stronger results in temperature control and durability.

The company expects the switch to improve efficiency in operations, logistics and workflow while also making better use of storage space and cutting plastic use and waste.

Coram supplies speciality infusion and nutrition therapies for patients with chronic and complex conditions.

Previously, these medicines were commonly delivered in EPS coolers and other packaging that could be difficult for patients to handle, store, discard or recycle.

Coram said the older materials may take years to decompose in landfill.

The company added that the new format is smaller, easier to flatten, and can be recycled or composted.

Much of the new system uses a "nested box" approach, allowing shipments to be combined into a single box.

The company has introduced the packaging first at pharmacies in Mendota Heights, Minnesota, Malvern, Pennsylvania and San Diego.

CVS Health chief sustainability officer and community impact vice-president Jenny McColloch said: “By replacing difficult-to-recycle materials with compostable and recyclable alternatives, we’re reducing waste, improving the patient experience, and removing thousands of pounds of plastic each year — a win for both patients and the planet.

“This packaging innovation reflects our commitment to embedding sustainability across our business and advancing our Healthy 2030 impact strategy.”
