Recycling

Caltech's commitment to waste reduction and recycling spans over 40 years. In the early 1960s a small recycling program was run by a number of volunteer graduate students. In 1979, one of the student volunteers, Professor Judith Cohen, returned to campus as a faculty member and petitioned the administration to establish a recycling center. The recycling center was run by Professor Cohen and a number of student volunteers.

Eventually, in 1989, a group of students created the Caltech Environmental Task Force (CETF). However, school and workload demands created challenges, and in order to continue with a consistent program, the Campus Recycling Program operations became the responsibility of the Buildings and Grounds Department. A recycling facility was built in 1993 and the recycling program has continued to divert waste resources from the landfill and serve as a model for other organizations.

Program Goals

• Minimize the overall quantity of waste generated.
• Minimize the negative environmental impacts of solid-waste management.
• Maximize campus community involvement.
• Educate the campus community to reduce, repair, reuse, and recycle.
• Improve measurements and standardize reporting practices.
• Integrate source-reduction, reuse, repair, and recycling programs into all phases of
  campus activities.

Resources Collected

Items are collected in categories: white paper, mix paper, newspaper, corrugated cardboard, newsprint, telephone books, magazines, aluminum, tin, glass, lab glass, platic and chipboard.

Program administration

Recycling on campus is provided by the Buildings and Grounds department. Two recycling specialists, one lift-truck, and a forklift are utilized to collect recyclables from campus buildings and consolidate the items in the recycling center. The recyclables are processed by Allan Company.

Buildings on campus have recycling bins. These bins are found in hallways, offices, laboratories, lunchrooms, mailbox, and photocopy areas. All bins are emptied by recycling personnel weekly. Cardboard recycling containers are located next to garbage dumpsters throughout the campus.

Office staff is also provided with small wastebasket size containers to store recyclable material, and are responsible for taking their material to the nearest recycling bin.

Requests for recycling bins should be directed to the Building and Grounds Department at (626) 395-4738. Please specify the type of bin needed.

Computer Equipment Recycling

Computer equipment recycling is provided to campus personnel only. Campus personnel who have items for recycling should contact transportation at (626) 395-4703, between the hours of 7:30 am and 4:00 pm, to make arrangements for pick up of the items. Computer equipment is not to be left on loading docks or dumpster areas as computer monitors need to be handled through the hazardous waste program.

How are students, faculty, and staff educated?

A variety of outreach programs are used to educate the campus community about reducing, reusing, and recycling; such as new student and employee orientation, the student's newspaper, and a number of campus sustainability events.
