All washers and dryers in SU's traditional residence halls are Energy Star rated units. The washers use 12.2 gallons per wash - a savings of three gallons from previous machines. In addition, washers feature an auto-injection system for high efficiency detergent to eliminate the need for large, plastic detergent and fabric softener bottles. The manufacturer of the machines - Mac-Gray Intelligent Laundry Systems - has included SU as one of the first three institutions in its new carbon neutral footprint program.
Most cleaning supplies are GS-37 certified, meaning they are biodegradable.
Cleaning equipment, such as mops and pads, is laundered to reduce the frequency of replacement.
Housekeeping hours are 4 p.m.-12:30 a.m. to reduce the amount of energy needed to heat and light the buildings for cleaning.
All residence halls and most academic buildings use coreless toilet tissue that has 70 percent post-consumer recycled waste.
Paper towels have been replaced in residence hall restrooms with hand dryers.
