Many of the items Penn students and faculty use on campus end up in the wrong place.

Though these items leave students' sight as soon as they are thrown into the trash, they end up either polluting the environment surrounding the local landfill or in piles that eventually become part of the everyday backdrop in developing nations.

Materials such as light bulbs, batteries, and electronics contain toxic metals that leach into the soil and ground water underneath a landfill. Prescription drugs that end up in the regular trash or flushed down a toilet contaminate drinking water supplies, according to the United States Food and Drug Administration. The improper disposal of these items leads companies to spend more time and money making new products, rather than reusing the original materials.

By disposing of hazardous waste properly, it's possible to avoid negative environmental, social, and political consequences. Here's what to know about recycling on Penn's campus:

There is another disposal area for light bulbs and batteries in the lobby of Rodin College House. Batteries can be disposed of in many other buildings on campus. When batteries are placed in any of these bins, tape should be placed on the positive and negative charges.
