Food packaging is a major source of trash in most households, so the kitchen is a good place to start. Singer shops for grains, nuts, spices and tea at a grocery store that offers a bulk organic section, and brings her own jars and cloth bags.
Singer said she builds her meals around the products she can find, but hasn't had a hard time finding package-free alternatives to important staples. "Ketchup is hard to find package-free," she said. "But most things like that, I can make my own."
