Many college campuses compost fruits and vegetables that would otherwise be thrown in the trash. Composting converts leftover fruits, vegetables, cardstock, paper and dead plants to fertilizer for growing plants. Toss all of organic matter into a composting bin. Turn the bin as often as possible. When organic matter decomposes, spread the compost in the soil at the base of plants. If there is not a can for compost located in the dining hall, speak with the administration about setting one up.
Colleges use a lot of paper. Because many campuses offer free printing, it is common to print material without second thought. If there are not recycle bins in the computer lab, speak with the Information Technology Department. It is also common to reuse paper that has already been printed on as scrap paper, using it for notes or reminders.
College campuses offer scenic and safe landscapes that are great for bicycling. There are many campuses that offer bike shops, recycling bike parts by building bikes out of scrap pieces. These programs offer mechanical experience to students as well as useful transportation devices.
Many colleges have converted to sustainable landscaping, especially utilizing succulents to decorate the campus. Recycle succulents by clipping pieces, and replanting them in the soil. They are easily transplanted, and require much less water than many other flowers and grasses.
