Reduction: Environmental Sustainability 

• Custodial Services uses accurate chemical dilution systems to eliminate unnecessary waste by measuring out the exact amount of cleaning product needed for a given task. With this dilution system, Iowa State mixes the chemical solutions on site which saves transportations costs and reduces associated carbon emissions.
• Due to increasing awareness of sustainability issues at Iowa State, Transportation Services uses bulk delivery and storage of all fluids, including fuel, oil, antifreeze and washer fluid, to eliminate the unnecessary waste of plastic and metal containers, as well as to reduce the number of deliveries, fuel usage and emissions.
