Montgomery County Public Schools, Rockville, Md.

2009 Green Cleaning Award winner of the School Districts Grand Award

Montgomery County Public Schools' (MCPS) Division of School Plant Operations (DSPO) began its transition to green cleaning in 1997 when it changed from oil-based wood floor finish to a water-based product. However, high standards for evaluation and approval of cleaning chemicals to be used in the school system long have been evaluated by a certified industrial hygienist, certified hazardous-materials managers, and occupational safety and health experts in the Department of Systemwide Safety and Environmental Services/Indoor Air Quality (IAQ) team. Factors that are considered are low volatile organic compounds (VOCs), non-carcinogen chemicals, low concentrate, flammability and exposure control. Any cleaning chemical to be used in the school system is evaluated by staff prior to its use. The product evaluation team in the DSPO also conducts effectiveness testing on products prior to use in schools.

The DSPO began using concentrated, Green Seal-certified (GSC) products in recyclable packaging in 2006. DSPO was able to replace five other products with the introduction of one GSC product.

Changes in the type of custodial equipment began in 2002. The DSPO purchased energy-efficient battery-operated scrubbers that dry floors faster, uses only clean water to capture dust particles from hard floor surfaces to prevent dust from being released into the air and changed from using mops and buckets. As a result, productivity doubled. In 2005, DSPO purchased high-speed burnishers to replace buffers. These burnishers are safer; are equipped with skirts and vacuums so they operate more cleanly, eliminating dust; are energy-efficient; eliminate the need to use a spray buffing chemical; and reduce the frequency of floor polishing. Consequently, productivity increased while the impact on the environment was reduced. To replace less efficient upright vacuums, brooms and dust mops, DSPO purchased backpack vacuums, which are certified by the Carpet and Rug Institute. Indoor air quality and the longevity of air filters was improved through the use of these vacuums, as they capture and retain more dust particles through a four-stage filtration system.
