Facilities Management Housekeeping Services promotes and supports sustainable cleaning standards and practices that provide for clean, healthy buildings and protect our environment. To the extent possible, Housekeeping Services purchases chemicals and supplies which have been Green Seal Certified and approved for low environmental impact. For example, our use of Green Seal Certified chemicals with low VOCs (Volatile Organic Compounds) and the use of high efficiency vacuum cleaners contribute to a healthier indoor air quality. Housekeeping Services uses restroom paper products made from 100% recycled paper. Check this website for updates on the state of Green Cleaning at the University of Maryland!
