Wiggins said the following items are difficult to recycle, but for those who are determined to find a way, it can be done: • Plastic food containers. When possible, Wiggins suggests you buy items in cardboard. Some containers — including those for yogurt and cottage cheese — can be recycled at Whole Foods. Or you can keep the containers to store leftovers or other items. • Chip bags. Many are a blend of paper and plastic. They can be mailed to TerraCycle, a company that makes items such as fashionable bags out of them.
