Due to the nature of clinical studies, many of the ancillary supply materials that go unused during studies are simply discarded. When a study ends, materials are re-purposed to another study whenever possible; however, if the materials cannot be repurposed, they are shipped back to the client’s warehouse for donation or disposal. PRA Health Sciences embedded resources recently collaborated with a client on a sustainability initiative which has proved to be not only environmentally beneficial but also to be cost-effective.
