Culture of Safety While we have collected water data from our manufacturing facilities since 2012, increased water data accuracy allows us to better understand our water sources, withdrawal rates, and discharges. In line with our commitment to conserve biodiversity, Avient has developed a biodiversity risk assessment framework that draws upon data from the World Wildlife Fund (WWF) Biodiversity Risk Filter.

Materials and their impact on patient safety Increased use of Quality by Design (QbD) processes means that more consideration needs to be given to materials used and their impact on patient safety. Documentation supporting relevant product safety and compliance data is available to all customers.
