Innovation in Cleaning for Custodians and Students
December 11 @ 3:00 pm - 4:00 pm ESTFree
Stanford University’s Residential and Dining Enterprises has adopted a green cleaning standard that has reduced chemical usage in residences by over 90%. The system engineers water by infusing it with ozone to create a solution as effective as traditional chemicals with no environmental or human health consequences, other than the use of electricity to generate the solution. Twenty percent of residences – or 32 buildings, 808,000sqft, with 29 full-time custodians and 2,509 students benefiting – are now using the system. In 2017 the new standard reduced over 350 gallons of chemicals from being purchased, stored and disposed of in sewer drains or as hazardous waste compared to previous years. The initiative took the chemical inventory list from over 30 to 2-3. In 2018 access to the green cleaning system was expanded to students to clean their own apartments and use as laundry detergent.
