GREEN CLEANING AT UNH 
"THE Green Sweep"
"Through the use of greener products, more effective cleaners, and precise dispenser systems, UNH Housekeeping has decreased the amount of cleaning product used by approximately 50% in the past 15 years."
Judy Koski, Gene Gargano and Jean Mitchell, Managers of UNH Facilities Housekeeping

Why green cleaning?
Cleaning products can have very negative impacts on human health and the environment. They frequently contain chemicals associated with cancer, reproductive disorders, respiratory ailments, eye or skin irritation, and other health conditions. They can also include toxins that adversely affect drinking water quality, lakes and streams, as well as plant and animal life. Furthermore, many cleaning products in concentrated form are considered hazardous waste, which presents handling, storage, and disposal concerns. Housekeepers who keep UNH buildings clean, as well as faculty, staff and students who enter and use the buildings, could be at risk for health conditions associated with some toxic chemicals found in cleaning products.
What makes a cleaning product green?
According to Green Seal®, a green cleaner is one that lessens its environmental impact at every stage of its life cycle, including packaging, and the ways in which it can be disposed after use (Green Seal, 1998). Product evaluations are conducted using a life-cycle approach to ensure that all significant environmental impacts of a product are considered, from raw materials extraction through manufacturing to use and disposal. Wherever possible, Green Seal® standards cite international test methods for evaluating product performance or environmental attributes such as toxicity, and its procedures conform to international standards for ecolabelling. For further information, please refer to the Green Seal® website.
What green cleaning does UNH do?
UNH Facilities Housekeeping is responsible for the internal cleaning of 75 out of the approximately 112 buildings on and off the UNH Durham campus, including academic and administrative buildings, residence halls, Health Services, the Field House and the Whittemore Center. They have continued to move toward less toxic cleaning solutions, where applicable, in order to ensure a healthy learning and working environment for students, faculty, staff, and building service workers. New greener products and practices are constantly being tested to see whether they meet expected standards. New product and green cleaning training happens at various times of the year when a new product is introduced by the vendor, or when new information needs to be disseminated to keep everyone updated. Judy Koski, Gene Gargano and Jean Mitchell, managers of Facilities Housekeeping, estimate that “through the use of greener products, more effective cleaners, and precise dispenser systems, UNH Housekeeping has decreased the amount of cleaning product used by approximately 50% in the past 15 years.” This constitutes a significant reduction in chemical use, and a cleaner, safer environment for anyone who enters and uses the buildings. The remaining 37 buildings of UNH are serviced by UNICCO. UNICCO has a similar green cleaning program which uses similar and different green products than used by UNH Housekeeping.
Green products and initiatives that are presently used by UNH Housekeeping
Green Cleaning Products:
- Green Seal® certified neutral /all-purpose cleaners are used for all floor and wall scrubbing.
- Green Seal® certified disinfectants, glass cleaners, carpet cleaners, and pre-spray and extraction shampoos are used throughout campus.
- RTD® Dispensing Systems are proportioning systems that are used for better control and measurement of cleaning solutions and products. This reduces human and aquatic toxicity and smog production potential. High efficiency filtration vacuum cleaners are used which improve air quality, provide employee productivity, and improve the working environment.
- Automatic Floor Scrubbers are used which pick up old water and do away with dirty water bucket mopping.
- Flat mopping systems using microfiber cloths are used where effective. This reduces the amount of water and cleaning product used.
- Linpol® Organic Floor Cleaner and Protectant is used in multiple buildings including the Whittemore Center.
Paper Products:
- The SCA toilet pape and roll towels used in restrooms on campus are 100% recycled paper and EcoLogo certified.
Mechanical Prevention and Practices:
- Effective mat systems are in place in all buildings, which dramatically reduces the amount of soil and moisture that gets tracked into a building.
- Discretionary use of disinfectants (considered toxic) are used only where necessary. Stripping of floors is only done on an “as needed” basis.
- Marmoleum® flooring which does not require stripping and floor finishes is encouraged in new buildings. (Marmoleum is made with natural raw materials and installed with solvent free adhesives.)
- Presently, Housekeeping is testing a cleaner that is “low foam,” which eliminates the need of a foamer therefore using less chemicals and leaving the machine to use the “green” product exclusively.
- Carpet cleaning accomplished with shampoo sprayed carpet (instead of soaking carpet with chemical cleaners) and then extracted with water cleaner.
- Carpet care systems use a special "green" formulation that uses no hazardous chemicals, which means no residues or special handling. It also uses 30 times less water than some wet cleaning methods to exceed water conservation standards outlined by the US Green Building Council.
Energy Savings
- UNH Facilities maintains an inventory of XLERATOR® hand dryers, which are hygienic, use 80% less energy than standard hand dryers, and result in a 95% cost savings over paper towels. Even taking the energy used into consideration they are usually more economical than paper towels and more sanitary.
- Electric hand dryers in restrooms are campus standard for new construction and renovation. UNH Housekeeping managers play an important role in reviewing Housekeeping finishes and standards in the design phase of new construction projects on campus.
- Unfortunately, to retrofit restrooms whose buildings are not undergoing renovation is an expensive undertaking and cannot be accomplished all at one time. However, UNH is working to escalate retrofits from paper towels to hand dryers where feasible. New installation locations in existing buildings are determined by UNH Housekeeping managers. They take into consideration the volume of towels being used, the type of location, and the need for electrical work needed to retrofit the location so it can use the dryers.
