As the first company to earn certification to NSF P391, Marstel-Day is able to differentiate its services and pursue preferred vendor status with organizations seeking more sustainable operating solutions.

This includes local, state and federal government agencies and others attempting to comply with U.S. Executive Order 13514, which helps ensure that 95 percent of government contracts include products and services with sustainable attributes (e.g. energy and water efficiency, recycled content). Many of these sustainable attributes are included in criteria for NSF P391.
