After doing some research, I was surprised at how many different waste items in your home can be used for compost. In order to have your compost "cook" so it is adequately decomposed, it is important to add both "browns" and "greens" to the pile, according to http://www.wikihow.com/Compost. "Browns" are high in carbon and include ashes, bark, corn stalks, fruit waste, leaves, shredded newspaper, pine needles, sawdust and vegetable stalks. As the website states, the "brown" items act as the "fiber" of your composted material. "Greens" are high in nitrogen, which activates the heating process and can include coffee grounds, food waste, garden waste, grass clippings, vegetable scraps and weeds, according to the website. You want to avoid weeds that have gone to seed because they can multiply in your pile. Meat products are not good for composting because they attract animals. It is also important not to add plants that have been treated with pesticides into your compost bin because they could contaminate the rest of the contents.
