Waste Minimization

Home Waste Management Waste Minimization

Waste Minimization is reduction in the quantity of hazardous wastes achieved through a conscientious application of innovative or alternative procedures. Simple adjustments to a process producing wastes (e.g. a teaching lab experiment, a vehicle cleaning operation, etc.) may be the only requirement to achieve some results. However, looking at the broader picture in the University environment, it is often difficult to recognize waste reductions due to the complex and changing growth patterns within the campus community. Reductions are often offset by increased staff and student growth and/or building construction.

Waste minimization often results in cost minimization. However, it is not uncommon to devise techniques to minimize costs without a corresponding reduction in waste quantities. For example, proper segregation of wastes will reduce disposal fees but only because these quantities are reassigned to more appropriate waste streams for cost effective disposal/treatment off site. While this is not technically waste minimization, it is still a beneficial process.

• Substitute less hazardous chemicals or ingredients for ones you are using now.
  Green Alternatives Wizard - This database provides information on alternatives to hazardous chemicals or processes. This is an MIT-developed tool made possible by an EPA People, Planet, and Prosperity grant. Information is subject to change.
• Order only the chemicals needed for the short term. You will spend more to dispose of larger amounts of unused chemicals than you will save by purchasing large orders to get quantity discounts.
• If you're dealing with common household chemicals, call the County Hotline for the latest updates on recommended and available substitutes.
• Test your ideas on the smallest scale practical to minimize disposal costs.
• Keep your wastes segregated by compatibility and type; avoid cross contamination as much as possible.

Start your waste minimization thought process by following the proper campus hazardous waste procedures.

• Review your inventory periodically to remove unwanted or unusable chemical stocks.
• Ensure proper identification is on all chemical containers.
• Attach a properly completed hazardous waste tag to each chemical waste container.
• Submit the container for pickup through the Online Tag system.
• Contact the Hazardous Waste Manager (9-3086) if you have any specific questions or need help with your project.
