Macalester College has taken a number of steps to reduce hazardous waste on campus. These include:
• Centralized chemical ordering system
• Laboratory exercises scaled down from grams to milligrams
• Many laboratory experiments redesigned to reduce the chemical hazards associated with them
• Yearly inventory of chemicals
• Chemical tracking system
Use of hazardous chemicals is subject to specific protocol outlined in the college’s Chemical-Hygiene Plan. It delineates specific procedures for chemical usage as well as detailed protocol to be used in the case of over exposure to hazardous chemicals. The disposal of this chemical waste is taken care of by a licensed recycling company contracted by Macalester. Macalester chooses which company to use based on methods for waste transport and disposal, company reputation, and cost. Macalester prefers to dispose of its hazardous wastes using combustion or fuel blending.
In its waste disposal practices, the college aims to be economical as well as environmentally responsible as possible.
Some additional steps include:
• Use of water miscible paints to allow safe disposal down the drain
• Recycling of used car batteries, oil, fluorescent bulbs, and other waste from the Facilities Services Department
• Remediation of select wastes in-house to reduce shipping (e.g. acid neutralization)
Macalester College has implemented a campus-wide inventory system to facilitate the reuse of laboratory chemicals. Each chemical bottle has a unique barcode. The computerized inventory system uses this barcode to store the bottle's information – including chemical information, container size and room location. Faculty can then always be aware of what chemicals are available for use. Faculty also do an evaluation on the use of chemicals once a year to better inform which kinds of chemicals should be purchased in lower quantity to reduce any unnecessary waste.
We use Dynamic Recycling, a certified R2 and NAID facility, for processing the College's electronic waste. Dynamic Recycling re-sells functioning systems and pays Macalester a portion of profit sharing.
