Move-out topics like packing, cleaning, and textbooks are covered in The Green Register's "The Green Minute." For instance, you can collect recycled boxes from local companies instead of buying brand-new boxes. Be sure to sell back your old textbooks, too, or donate them to local schools. And have leftover furniture? Sell it online or host a garage sale. For more tips, learn about Arizona State University's Ditch the Dumpster program.
